Being a test pilot for Robinson Helicopter for 30 years and building Tesla powered Ford Mustangs I love the idea. The only issue is that flying for X number of minutes you don't get lighter with fuel being burned off so have have be careful of keeping enough hover battery power left to land safely as the weight does not change.
Yes, that's a burden that electric vehicles will probably have forever. But if some day we develop batteries with more energy density than liquid fuels, they might make up for the weight.
The Mosquito has great auto-rotation capability, so any engine loss can still be recovered safely.
@@aeroengguy448 That is great but that's not what I'm talking about. You have to be very conservative on your battery so you have enough power available when doing a normal landing. You need as much hover power in the beginning as in the end as the helicopter won't get any advantage from burning off fuel making the helicopter lighter. Just something that has to be learned. Pilot training is all.
its still a very good initial training device with ability to emulate different power trains
@@Roadstercycle that must of been a dream job, and you must of been an very successful pilot maybe even military..I'm not a pilot but I've always observed the pilot throttle back to come down then giving it the throttle and just before touchdown backing off the throttle..I look forward to seeing a hybrid version as well
I appreciate the specific information about the components and the power information (e.g. 40 kW in hover, and even the motor speed of 2750 RPM). I recognized the Emrax motor design, but wouldn't have been sure of the model without it being stated, and I recognized the LG Chem modules but the confirmation is good. Prototype electric aircraft are often hard to assess without real power and energy data.
But its easier for them to make up statistics if they don't provide any real world numbers ;) . How can you go and tell your customers you plan to give it a 3 hour flight time if at the same time you tell them there is 30kwh of energy on board and you require 40kw just to hover :P

Great to see people keep experimenting. Sooner or later a breakthrough in battery technology will come.

@@bitrage. Actually the Chinese came out with a battery in April that is supposedly able to power airplanes. The company name is CATL if you want to search it up
It IS coming..quick charges, light weight and range exceeding a gas equivalant....these are the Holy Grail of the EV industry, that have held it back in times past but are about to be resolved ... this will affect ALL EV's be it aviation ,automotive ect.
Sodium Cobalt batteries have been discovered today (24-04-2024) which will allow charges within seconds and doubling that found from Lithium batteries. Let's hope science beings this main stream!

This would get me back and forth from the island. If they can hover for 25 minutes right now, its already capable of making the trip.

I like how you didn't cut out the engine-off rotor slow down shot and left the entire thing, kind of like a mini meditation, nice.
I don't think I've ever commented on this channel before, but I would love for you to follow the development of this helicopter! As battery technology continues to improve, I think we're going to see more and more aircraft like this, with steadily improving performance.
Yes this is a great leap. Would definitely be interested in developing something like this although I'm concerned about battery times
I served in the Marine Corps in aviation during the Vietnam Era. Mostly helicopters where I was. Loved every minute of it being around those flying machines. No fixed-wing for me!!
Че сбежал со ветнама ?
This is insane. I really like it. It’s so instant power no waiting at all. It’s a way forward definitely
I'm really curious to see what fault tolerance you can work into the Sevcon Gen4, typically they just open the main contactor and drop all power when they fault out which could be sketchy if don't have enough elevation to autorotate. LG chem cells are a great choice for this, really looking forward to future development of electric craft like this!
Matt here. That is one of the concerns I had with using this controller. You are somewhat limited with how you want the controller to handle a fault situation. However we did already test it in an auto from about 4 ft and our pilot was able to successfully pull pitch quick enough and counter the tail to have a safe albeit quick landing without any damage. The problem I am actually looking at how to address is a temp fault (not requiring a key-switch reset) like an over-temp of the controller (primarily because we are spinning the motor to slow for the power we want, we are a bit too far over the controllers continuous amp rating to the motor), where it will cut back for about 0.5 second and then suddenly re-engage power. This is definitely a new experience for the pilot, where he would be making a tail correction in the auto to keep it from rotation and all of a sudden power is back and it rotates suddenly).
@@glory122 Glad to hear your auto tests have gone well. EV motor controls are still in their infancy and need projects like this to drive the requirements for aspects like fault handling. The Gen4 has a thermal cutback curve, (Figure 12) in the manual if you can dial in the thermal managment to stay under ~75-78C you'll be golden. If the high current draw is intermittent you increase the mass of the heatsink to try and get a little more thermal resistance for those flucutations. I'm sure you've looked at the options Curtis has for motor controls, they have better fault communication but I'm not sure if they are better at fault handling.
You bring up an excellent point about fault tolerance and the Sevcon Gen4. Ensuring a safe response in case of faults is indeed crucial, especially when elevation might be limited. It's encouraging to see your thoughtful consideration for the technical aspects of electric aircraft development.
I'd love to see a follow-up! If they can get it up to one-hour flight time that would be a great follow-up!
It crashed 2 days ago and burned
@@michaelvoorhees5978 I'm sorry to hear that :-( Was the pilot okay? Hopefully at some time a new version will be built (with longer-range etc.).

Yea I would like to see the advancements they make on this. That is awesome. Hybrid is the way to go until they come up with a better battery chemistry (or release one anyway). That is so cool! I have been watching the Mosquito helicopters for years on youtube. I don't think I could ever fly one. Ill stick with FAR103 fixed wings. LoL
You should configure your battery packs in parallel so to have redundancy. If one of your packs goes wrong then the whole thing goes down because you are wired in series. Hope you have a good BMS with plenty of heat regulating mosftes and something to regulate cell balancing etc...
That’s such an exciting prototype! Obviously the challenge is to extend that runtime and range.. as the battery technology catches up these kinds of aircraft will be such a cool and novel mode of transport for the people who are lucky enough to be involved!
The entire chopper chassis would probably have to be completely remade to encorporate all of the added weight and packaging :/ Maybe a fundraiser model with the size of a robinson or a little bird? But it is a vital step for their developement as a company!
modify a glider to an EV and design features to allow it to land vertically. helicopters are very inefficient and should be phased out IMO.
Solid state batteries are difficult to get right but a few companies have made some pretty good progress. Those batteries would really unlock the potential here. High capacity, light, and safe.
25 MINUTES OF FLIGHT TIME? YOU MAY AS WELL GO BACK TO GAS ENGINES. THIS ISNT PROGRESS THIS IS GOING BACKWARDS LOL
@@illuminatedperspectives2894 the first electric cars had a thousand pounds of lead acid batteries and had a range of 20 miles. Look how far we've come from that, and remember that nearly ALL the massive ev advancement has been in just the last 10 years. This is a first gen, essentially prototype electric helicopter. Imagine in just 5 years how much more advanced they will be! Now imagine 10 years!
0:35 The way he says Norbert and then realizes how silly it was once he hears it correctly made me lol
Yes, definitely do a follow up on this fascinating project!
Very cool, love the green color. Based on the rotor blade's shape (like an airplane wing) at 10:45, I'm guessing it rotates counter-clockwise?
This is really good to see - the best innovation seems to come from small companies. I realise you're using the existing airframe but the motor and inverter would sit beautifully just below the rotor (like most turbines), benefiting from a cooling downwash and freeing up space to fit the batteries in a more aerodynamic/inboard position.
While I would put the inverter and the rest of the support package (cooling, etc) below the boom, I agree that placing the motor up there on the shaft from the belt drive pulley to the tail rotor shaft gearbox would free up valuable room immediately behind the mast line, below the boom. For those not familiar with the Emrax motors, I'll note that they have a hollow shaft which would facilitate installation coaxially over a shaft, although the bore of the Emrax 228 model is only 17 mm in diameter.
yeah less red tape.
I would actually use two motors (one for main and the other for tail rotor) mounted directly to each axle to maximise efficiency.
@@julianroa9905 That would be problematic for autorotation if you had an electrical failure that killed power to both motors.
@@julianroa9905 separate motors are fine in a radio-controlled toy, but in an aircraft carrying a person they would be an unacceptable (to me) risk, because if high-voltage drive power fails yaw control is lost. It would be okay with sufficient redundancy and a high enough level of design and testing... but this aircraft is not constructed to anything like that level.
Besides what it takes to get the cobalt to build the batteries for things like this, I love it.
Very impressive the amount of sound out of the equation is excellent for stealth work or hunting whit out spooking everything. 👍
THEY ARE REALLY DOING SOME GOOD STUFF THERE!
It is truly interesting... certainly! Thanks for watching!
15:08 Yes I would like to see a follow-up on this. Mainly I'd like to see what the hybrid solution will be. Because as it stands right now full electric is not the answer. But a hybrid would be. But we shall see what their research provides. My thoughts cheers Dion
8:50 I'm impressed that the cameraman isn't afraid of getting chopped up by those blades considering it's still a prototype, anything can happen
DEFINTELY want to see more follow up on this episode. Any guesses at public release estimates and pricing estimates would be great. Also, with the added weight of either all the batteries or a hybrid style, additional engine/generator, would this aircraft still qualify as an Ultralight according to FAA regulations? The weight was not addressed in this episode.
I suggest you and the video creator not wasting time on battery-powered heli: it is DOA just from the energy density alone. Don't wanna agree with me? The battery can improve with time? There is a limit from a chemical-thermodynamics alone- pretty much like the second law of thermodynamics ruled out any perpetual motion machine.
@@irvinewayne4086 Not the same thing but i've seen powertool batteries like the m18 Milwaukee go from 2ah 300-400 charge cycles with a 400watt output to 6ah with the same sized and weight and 3000 charge cycles and 1800watt output. There is also improvements to the inverter efficiency and weight too to be had. I remember going to job sites in the late 90s and it being a spaghetti mess of cords cause the battery powertools just weren't up to the task. Today only the air compressor and shop vac seem to be the only corded tools that are common anymore. That is only cause of increasing battery power/energy density. Idk if it will ever improve enough for a transatlantic flight but there is still much room for improvement
I had no idea it could get this small. That engine is practically sitting in air conditioning. Thank you for your build!
Motor
@@jamesbizs its the battery pack
@@jamesbizs an engine is a motor and vice versa. The basic definition of engine is a machine with moving parts that converts power into motion.
This is a great project, done very well. I look forward to how it develops. Personally I always prefer series hybrid, your battery would effectively become the reserve for if the engine quits, or if you have a sudden power draw for whatever reason. Then the engine can be at its most efficient. It works for trains lol
But what's the point if we charge the batteries with fossil fuels. What has been accomplished other than making more toxic waist from battery production? I'm just not seeing the benefits of going electric. We can never hope to produce enough electricity with sun or wind, so why bother?
@@okgroomer1966 I think Thalass just gave us the point, power train redundancy in the helicopter fixes an imminent danger to life and health...
Nice looking helicopter, but being all electric would have its drawbacks, range would be affected by head winds, temperature, the draw of instruments, an communication equipment lad well as unforseen weather. To me I don’t think I would want to fly one all electric, I feel the same way about electric cars an trucks, people that have these electric pickups an have tried to tow a trailer ( empty or loaded ) have found out that even being able to tow the range drops significantly an chargers are hard to find an takes a long time to charge them back up if you can find a working charger or one that produced enough wattage to charge the batteries. Electric may provide you with horsepower an instant torque but not the range as of a gas or diesel engine can. Plus their very expensive right now an some have a tendency to catch fire for some reason an the fire burns hotter an is harder to put out than gas or diesel fuel. Maybe in time they can overcome those problems though at my age I may not live to see it. I do wish them luck on their project an that they can get it working.
Thalass, gasoline engine plus generator plus fuel added to the already existing batteries and motors would make it so heavy it would get off the ground.
25 MINUTES OF FLIGHT TIME? YOU MAY AS WELL GO BACK TO GAS ENGINES. THIS ISNT PROGRESS THIS IS GOING BACKWARDS LOL
Maybe needs another 15 to 20 years of battery development to be a viable option
They just need to build a hybrid. Slap a small gasoline generator on there and you can use a tiny battery then.
Maybe two years
It's interesting how smart phone is progressing...
Fifty years development wouldn’t get me in it
@@LegendLength no hybrids bad for enviroment
Like the sound👍. Only the flight time is too far from the gas version. I like the mosquitoes design👍. Keep up the good work
Love this 10:00 - You should do a brief talk while hovering as often the mic "gains" down if the overall noise is high meaning it will sound quieter than it really is.
Matthew here. It's pretty darn silent at flat pitch, dead silent up until about 1000rpm. However the moment you pull pitch it definitely gets louder. It's a lot quieter than our piston or turbine options, but not silent. One of the interesting things we found was how loud the tail rotor is, especially when rotating, you can hear it chopping through the air.
These guys will obviously manage to accomplish decent flying time using batteries very soon. I was wondering if it will be possible to create versions with turbo and other options that liquid fueled versions have? Do the military have battery testing going on at the moment? The military have silent mode on some liquid fueled copters, so with the advent of battery copters, stealth mode should be easier to create?
Would like to stay current of your progress. Very interested and an awesome job.
Yes ,any additional info on this build would be awesome . Type and brand of vcu or control unit ,type and brand of bms and details of batteries . Price point of items for conversion would be nice to for others pondering doing their own . Trying to share the info needed to keep the experimentals going! Thamks
They don't want to say (for legal reasons), but the battery modules appear to be LG Chem 16S 1P as built for the Chrysler Pacifica Hybrid van; they were available from many suppliers for a while. It shouldn't need a VCU.
@@brianb-p6586 Thanks
I would also think that when solid state batteries show up projects like this will really take off.
I see what you did there
Not really. Solid state will only double the flight time. So it goes from 20 to 40 minutes hover time. But then you have to factor in some margins and you are left with maybe 30 minutes or less depending on usage. That is still useless. A gas helicopter can fly for several hours. Hydrogen fuel cells will be somewhere in between.
Solid state is much safer and lighter. An Aeros ANT can fly under power for more than an hour. If it had solid state then it would be even more fun
@@jimj2683 30 minutes may be fine for many uses. That could move someone 30+ miles. Rarely do helicopters travel for hours on end from point to point.
Very interesting short.thanks 😊
Fantastic and I'm proud of you indeed 😀
Yes, EAC, would love to know more about the future APU (gas motor providing power for an electric motor) option works. Especially would love to know the trade-offs on this type of configuration vs just using battery power plant. In general, would love for you to explore why this type of configuration (APU) works for cars, but why it (seems) to not work in electric aircraft. Thanks for your channel.
Bryan, this is a big step for C-FX. Like he said, the batteries just aren't there yet. They definitely have an interesting concept for sure. Me personally, nothing beats a turbine chopper!

@@lancedooley7558 Ummmmmm yes… they definitely will … wtf are you talking about??Deal with it buddy
@@lp712 will never happen. Energy density of fuel is 33x of a junk battery. It will never supercede that and it will never beat law of thermodynamics. Just like this rhetoric of climate change delusion by leftist elitist.
❤ Geniuses🤝🏾 Fellous more of you are a need for our Future, well Done Cheps , well Played 🤜🏻🤛🏿
This is exactly how we fly our RC helicopters. Amazing that stuff can apply to a full-size keep going.
I’m currently trying to design a hovercraft system that uses a small gas generator to run two electric motors for flying. This should offer more range and less noise.
Why so complicated?
Electric motors are light enough to carry a spare as well gas generators. Until battery tech is capable of better power we can get farther on less gas.
Yes! Please do a follow up with these guys as they continue to develop. 25 mins in the hover is one thing but do they have numbers for actual point to point which is a bit more efficient. Even 25 mins isn't so bad as a point to point hopper if that suits your mission. Half hour charging is fine because you would never fully drain the battery anyway.
I doubt it gets 5 minutes with a pilot. they even had to edit the seconds long flight and then show a jet powered one. electric airplanes can barely get 20 minutes.
How do you auto rotate in an emergency with something that has an electric motor with no clutches to disengage the motor from the blades?
@@thecloneguyz it looks like the motor powers a belt from the motor to the rotor.
@@thecloneguyz The drive system is the same arrangement as they use with a piston engine. the belt drive. An electric motor has very low spinning mass and no compression so it may not even be needed to disengage the motor. Or the belt drive has an auto clutch that lets the rotor spin when the motor stops providing power.
@@frankyflowers The KW draw in the hover and battery capacity seems about right for 20-25 in hover. I assume that's ground effect hover though. They look like Nissan Leaf batteries. Other electric converted helicopters (there is/was a R22 testbed) also got around 20 minutes. They did mention that this is in very early flight test stage so I wouldn't expect them to go far just yet. The Pipistrel Electro 2 seat fixed wing trainer gets one hour flight time plus reserves.
Great channel, and great aircraft, too! Could you please break down/list the major components used in this mosquito helo, as some of the parts may be invaluable for people trying to create their own 'contraptions'?
I would love to see a follow-up. I am curious if a generator setup like the Chevy Volt or BMW i3's range extender would work well for something like this.
Nice to see it make it in the global market and see the feed back...
I love how many people are commenting that it has a short flight time or they have a long way to go. IT"S a prototype folks. Calm down
Yes, it's just a prototype. Unfortunately, since the fundamental endurance problem is the weight of the battery, there is not much improvement likely any time soon, even with unlimited development of the aircraft.
@@brianb-p6586 🤣🤣🤣 your the exact same person that said airplanes, cars and the internet were fads. Oh you probably thought cell phones weren't going to last either 😂🤣😅
@@antr7493 No, I just acknowledge reality. A battery-electric helicopter will work well, with higher battery energy density. Even this one will work well for very short flights, once they fix the drive ratio; it is just a prototype, so that sort of change should be expected. By the way, I'm one of the people who gave your post a "thumbs up", but I've taken that away now.
That fact that you wrote….. “Calm down “. You’re just as guilty.
It's Great to see companies going electric. I think that a lot of the direction should be put towards the charging as that's the problem with electric systems there should be more work pushed towards charging while running. I know it will take time and it will get there. With more and more companies going in that direction shouldn't be too far away. Much love ❤️ from Australia 🇦🇺 and fly safe.
charging while running? you want to fly with a extention cord? lol or you meant charging a different set of batteries while you fly. And the main problem is weight in aircrafts, 25min in hoover is pretty meh....and using up all the rare resources for batteries and all the pollution when making them is also pretty bad
It doesn't make sense to have a single seater electric helicopter, just buy a regolar petrol one.
@@faustinpippin9208 10 hours of charging for a 25 minutes flight. That's not on my bucket list. With all the vibration I would be concerned about those batteries short circuiting, we all know how LiPo behave when on fire.
Funny thing about EVs. The more powerful the battery, the heavier it weighs . Not what you want in an aircraft. EVs are not the answer. Very impractical, environmentally unfriendly.
@@europaeuropa3673 that is dependant on the charger, i guess they dont have the need to charge faster so they did not buy the faster charger(which is just a case of buying a larger/more powerful one), the biggest concern is the power lines running to the charger, if you try to refuel anything else thru a long straw it takes a long time also.
I'm from Indonesia, I'm very amazed to watch this video and I want to see the next video
Awesome. Battery density is just going to continue to improve so I _really hope you keep the all battery option. The hybrid in my engineering experience would introduce a lot of complexity...but hey, I am not the designer and you already have a fantastic all batt test vehicle.
Cool in concept. Maybe someday we'll overcome that whole energy density thing.
It doesn't make sense, just buy a Cabri or R22 and you got a better helicopter today, not in 10 years.

@@missingMBR agree, but I think if you "could" pump enough amps through at 12-24V it would have quite a bit of torque.. But agree 100% its not the safest, or best way.. Way too much resistance as well at lower volts...
@@TheRusschannel sorry I got confused there. Voltage is proportional to speed. Current is proportional to torque. So you're absolutely right. You could throw enormous gauge wires at the motor and achieve the same amount of torque. But is it practical, not very, haha.
@@missingMBR they "may" also find going to AC voltage like the bigger EV cars use, may have some weight benefits, and lower temperatures..Will be interesting to see how this pans out and what they end up using.
It sounds just like some of my radio control helicopters. All you hear is the rotor noise.
I live on the north fork of Long Island, (NY), work on the south fork, and driving takes 45-55mins, with one of these it’d take me less than 10 mins. Take my money!! 25 mins is more than enough to get me to work and normally work 24hr shifts so I could charge during the shift.
This is so great! Glad people are working on electrifying things. They should use battery regeneration as a rotor break.
I'd like to know whether they think a separate motor for the tail rotor would be a good idea, particularly if they were clean-sheet designing an electric-only model. How much room for optimization do they think electric motors could allow, if they completely drop provisioning for a traditional drive-train?
Matt here. It's an idea we have discussed. We would be able to cut out some of the losses associated with the splitter gearbox for the tail/main rotor, the driveshaft, and tail gearbox. Main thing holding us back is that this would need it's own motor controller, some sort of redundant battery, and rotary encoders for the pedals. You really really don't want to lose tail rotor authority in a helicopter, so it would need a lot of testing. Currently we are testing the electric power-plant before we start thinking about any changes to our drive-line, which is well proven.
Those tiny model helicopters always have a large gear covering the whole underside of the cabin. I figured that this is the lowest friction solution to get some torque onto the shaft. Hidden from the downwash. Does not obstruct the view. Redundant motors: one in the front, one in the back.
Are you planning to add any redundancies for the motor and the controller (in case of failure)?
I think it’s a fine job well done !
Wow amazing
I would take this helicopter any time over all those 4 and tons of motors electric manned drones that are tend to crash one day sooner or later if one motor goes down. this helicopter with conventional system (but electric power) will still do auto gyro landing if motor goes out. the safest and best, most efficient way to fly is helicopter and now we have electric wow. Wish I had money or wish you were hiring, i would love to come and work with you guys :)
Perhaps the quadcopters are cheaper to make?
Hopefully they let you test one out 🤓
@@jimj2683 cheaper and easier, thats why everyone goes that way. its just scaled up drones with seats. not safe at all. one rotor has issues and you crash. imagine having a life on board. With this helicopter, it will do auto gyro landing, and if they provide a parachute for whole system that would be even double safe. I would take helicopters any time with eyes closed over those new drones coming out with so much promises but no safety features at all.
@@dronepilot260rc i would love to, if they allow me to test it. i would even work for them in development team and test pilot :)
My exact thoughts. I don't trust anything that can't land unpowered.
These things are perfect for pilot training ☺️
Yeah, if the school charges by the quarter hour...
No it’s not good practice… they have simulator cockpits for a reason… a lot of people won’t die this way.
Great work ..congratulations from Sri Lanka
very genius and extraordinary, I really salute
With a SEVCON Gen4 and an LG battery, this is clearly a flying Twizy … even the lacking doors are there ^_^
Cool. (Long way to go for flying over a couple of hours)
Yes. Agreed 100%. But you must first START before you can ever get to the finish line. Good to see companies investing in new tech if nothing else just to "play" with ideas. Thanks for watching today!
Man i bet this thing could be glorious with the new CATL batteries that were revealed!
amazing work.
Very cool folks. Small company’s thinking out of the box. I look forward to seeing what’s next..
What do you think (when using custom shaped batteries) would be your company's dream energy density per kilo? Or should I say, what would be a minimum viable energy density for your battery packs to make the heli an attractive option to buyers? Very interesting video guys, very impressive.
10x more dense than today... for small helicopter that now uses internal combustion engine. for gas turbine ones... 15-20x more energy dense.
Very cool! I'd love to be able to play with this. What's the torque percentage indication at hover out of ground effect on a Mosquito and what is max? 40 kW and 2750 rpm gives 138,9 Nm of motor torque. Sounds like you need lower kv motor to keep running it if you're maxing out the current limit of the controller now.
OK sure, thank you father. 🙄
It's a good idea to put two belts for redundancy but I would put a raised ridge on both pulleys to separate them in case one breaks it won't take the other one.
I built my own batteri\y packs and they worked just fine. I am not an "engineer" but making battery packs and wiring them correctly with the BMS and other requirements is not difficult nor does it require an engineer.
"nor does it require an engineer" but it helps if you know what you are doing.
This is a terrible attitude. Battery powered aircraft are no joke. A fiery death like the Siemens tragedy is the worst way to go. Please don't trivialize the risks.
You can make your own packs, but they won't be any more energy-dense than the properly designed modules that they are using, so there's no point.
Be sure and tell that to John Denver when you see him.
for a full size flying helicopter ? show us a video
Very cool, hopefully they can get more than 20 to 25 minutes flight time out of it in the future
Not until batteries become lighter and more powerful!!!
@@toddsterling4949 as they said there is still a lot of tuning to do, but I have a feeling you're correct for the most part.
