fully 3d printed 50mm speed jet! she had a good maiden flight. very positive flight characteristics. I need to make some minor adjustments to the design and print a new one.

"omg it flys" yk your an engineer when your own work surprises you
Happens to me all the time. Now I need help to get my drone off that Verizon tower....
A name from the 70's comes to mind, "Lawn Dart."
😄
Jart was the brand name and a great name for this plane.
@@christiansmith2730 You are exactly right. I just used the generic name my kids used.
That is a pretty great name. I was going to suggest something but yours is better than what I was going to say. Lawn Dart or Jart would be great. Jart in particular would be a portmanteau of "Jet" and "Dart."

Aeronautic Engineer : "Anything will fly with enough trust".
One of my sons at around age 2 decided he could fly like a bird, and “trusting” his beliefs he did a belly flop off the coffee table and made about half a flap of his arms/wings before going splat on the floor. Maybe he needed more trust.
Fun fact: on average that amount of thrust is twice the weight of the mass. So if your kid weighs 60lbs, he needs to generate 120lbs of thrust.
Yes even a brick, from my catapult.
@@Technicallyaddicted Launch a child protocol, ?
Trust? Or thrust?
Great work. There's nothing not to like about this. Your son's getting some great memories.
Thanks he absolutely loves seeing the new projects fly
Not sure if anyone has mentioned it but it reminds me of the Quest jet from the old Johnny Quest cartoon from the late 60's (?). Impressive.
I’ll need to look that up!
Spot on.
Quality time with the young fellow makes this video a big win alone. Congratulations on an excellent build.
Sceptical Kid: " ... It's actually flying! " From what I've seen it's actually brilliant design.
"Who knew the skinny nose would affect the balance so much?" Archimedes did ...
I wonder if the lift under that long nose once it was flying offset the forward CG somewhat. Beautiful, stunning look, very aggressive. I love it! Flies very nicely, too. Congrats!
This model is beautiful and so quiet. I like the current speed because it makes good visuals for the camera. :D
Make the intake into more of a U shape so it can conform to the fues more. This would eliminate the areas of dead air where the intake is blending into the fues
The reason the intake might be separate from the fuselage is to reduce the amount of disturbed air entering the intake. Look at US military jets such as the F-4, F-15, F-16, XB-70. Is this what you were talking about?
@@thedoctor4637 I know. Keep the intake seperated and make it U shaped to eliminate the dead spaces where it blends into the fues. Imagine an F4 phantom with round intakes off to the sides. See what I mean?
Kewl, used fly RC’s years ago, my only problem was I had to keep making them bigger so I could se them.
Kewl?
Try first person view, it's really fun.
@@aidenkahn4338 Back in the day that's how we talked, son
@@ChoChan776 Please don't refer to someone that you don't know as "son" It's a bit disrespectful. I thought he was trying to talk about "Kyle" I understand he mean like cool.
That was awesome. You should stick an FPV system in it and go flat out!
Anything will fly as long as the CG IS PERFECT 😂 and it looks perfect to me
Hello, Greetings from Germany! I looked at your flight with high interest, after I was flying many Deltas. On your 2. flight the air flow broke off at the outer wing. This Problem (I often had) can only be solved with less pitch at the wing tips. Looking forward to your next test- flights!
Winglets at the wingtips and fences like the mig 15 can help.
double delta wings, tiny canards and thrust vectoring "vertical rudder" should make it easier to handle yet faster as the drag is significantly lower then. Love the hull shape and intake setup!
You need a catapult launch system and if you want to easily correct the CG issue try a cranked delta configuration similar to the F16XL, make it for speed and slow landings at the same time
Wow! Amazing airplane! Great job.
Incredible, keep up the good work and thanks for posting.
That was an awesome flight.. Bravo
hahaha "holy sh*t it's flying". ... love it. Great job!
Super amazing 1st flight.
I love the joy that can be heard from your voice, keep at it man!
Looks like a love child between an F-106 & F-107. Flies nice though.
AMAZING first flight!
Congrats on the first flight! Beautiful machine!
That dad's father & son time is incredible ❤❤
Looks like a blast ! Cool design!
Beautiful aircraft - great to see the delta with a top mounted s-duct flies so beautifully! We're building a slightly larger jet-powered aircraft with a similar configuration to yours, it would be great to have a chat some time!
Thank you!! Yes this was a tricky design to get right initially due to the intake. S-duct was totally necessary due to being a belly lander. V2 has a 10” shorter nose and finally balances👍🏻 V2 flight video coming soon. Love to chat
Woahh I just checked out your channel that’s so cool! If you haven’t flown that yet I can give you some pointers. You’ll need to reduce your roll rate down to 35% max. We have very similar air frame profiles. My CG calculation was not even close to the actual. Email me anytime you’d like. Builtfastkyle@gmail.com
@@hotlapkyle Really looking forward to seeing the v2 video! Thanks for your advice - the roll rate reduction is something we have recently learned the hard way on our foamies we've been flying - was way too responsive before and led to a few crashes! The CG tuning has also been a lot of work too, conventional methods for working out neutral point break down for delta wings. We've been able to refine this by taking measurements in the wind tunnel and using CFD to give an exact estimate (we also "flew" the aircraft in the wind tunnel recently - video coming soon). Interestingly the neutral point also changes at angles of attack above ~15 degrees which makes trimming the stability even harder. Thanks for sending your email - i'll keep in touch!
@@TheMachInitiative I can’t wait to see your next video!!
Very cool design! Great work, let's see more!
Great innovation! Your helper seems to be very enthusiastic! LOL
Great job, thanks for sharing 👍
If that thing was built and sold like that ppl would not want it super fast. it would be fine the way it is. Really nice & stable for its appearances very nice control aspects too.
The young lad has super powers, he can hear a problem on a small super fast plane in full flight. He can even determine the location of the event . This is Kalel.
Haha yes
Great little design!
I'm amazed the X-Acto din't fall off.
Great job your son having a blast😂
holy shit at the end🙈, the maiden flight was absolut epic and top 💯.....thumbs up👍👍
''ohmygoditflies'' ''omahgod'' had to repeat that a few times, the sheer astonishment can be heard xD
Another name from the seventies comes to mind speedy racer this was like a cartoon car
That is a GORGEOUS airplane, sir! Looks like an early cold war X-plane, and they are by far my favorites. I haven't tried the XFly 50mm units, so I can't speak to those, but I have a couple RC Lander 10-blade 50mm alloy stator 4300kv units (~$50) and they really rip on 4s. The other 50mm class I've really liked are the QX units. One thing to remember about the 50mm class especially, though, is unfortunately, many otherwise decent fan units come with motors that aren't the greatest and don't really push the fans themselves to the max they're capable of.
Nice looking aeroplane . Good luck for the future with this aircraft ! :-)
Awesome nice , greetings from Remi, Belgium
It's absolutely stunning!! Love it! I would suggest you (being flying fan jet for pretty much time), to ensure the intake surface has to be at least same area as the fan and the exhaust s/be about 10% smaller.
Congrats!!! Make the rudder a little taller. The inlet is probably disrupting the airflow over it a good bit. That will fix some of the low speed rolling.
The ending depicts all my model aircraft experience as a youngster
I kept thinking, "that's mid power model rocket parts with glass over it." Then you said"print". Awesome!
Nice flight!
You’ve already hit Boeing beat! Nothing fell off
Excellent man
I thought It was a fake video because it never changed aspect and could barely see it, then realized I was following a smudge on my TV. Cool looking plane
Haha same when I re watched it. A speck of dirt on my phone lol. I’ve since upgraded my camera and learned the settings better 👍🏻
WELL DONE ! 😎 its going to be a rocket !
The Hyper Dart!
Im really pleased for you mate , it looked really good in flight . beautiful job.🙂👍 Shame about the end though.
Great job. I love what you built! And everybody crashes……
And I do. A lot 😂
Looks fast. 👍💙😎
Wow! Awesome
This is really cool, subbed 😃 👍
Send it !! 😮🎉
Impressive! You have a stable platform. Your brother is sponging up engineering flight 🛫 basics! Now Modify, Improve and leverage a payload delivery: 🇺🇸 🙏🏼🕊️
Excellent design and first flight. Reminds me of a miniature Shahed drone, you should send the schematics to the Ukrainian military they could really use this. So quiet 😎
Beautiful design and great job! If you glue a couple of carbon fiber rods in the fuse, it will greatly increase the strength. I’ll be happy to send some rods!
I haven’t used any spar or carbon rods in any of my designs yet! Thanks though 👍🏻👍🏻
😮I have been flying EDF and hand launching . 1. Being right handed person, I never use mode 2 on my transmitter. I use mode 1 , so that my left hand is always on the left stick , giving me elevator and rudder control ,during the hand launch. 2. The edf should be mounted slight upthrust and left thrust for sucessful hand launch...when view from the rear. 3. Always have ample space for the battery compartment for ease of getting the c.g. balance.
If the worst was to happen...you could name it " The Skewer!" Nice build and congrats!!!
😂
@@hotlapkyle Great to see that you take other people into consideration as well and you involve your son as well....traits of a good father!! Bless you!!
Flying as a father. We are a genre of our own
You can add canard wings to support the weight in the front effectively shifting the center of gravity by shifting the wing area. But of course it will add a little drag.
Mount a hollow tube on top of the tail. Aerodynamic but you can add of subtract weight as needed using neodymium magnets.
Sweet ‼️
Try a good powerful under-arm launch upwards at approx 30 degree angle without power until it has left you hand (use thumb to open the throttle as you release it)... Works for me with heavy wing load delta pushers....should also work in your application too methinks...
Ooh! I like it!
Nice Wooh! @2:58. Good recovery. I would add some expo so it doesn’t fly so squirrelly.
I forget what the exact original designation of the SR71 was but it did not start out as that. I followed the project since I was like 13 years old the design the whole thing just amazed me. Originally the skeptics really put the thing down when it was on the drawing boards. Just so folks know Clarence Kelly was the birds father and it was not just Lockheed that made it fly. North American was deeply involved in design concepts over Lockheed providing the power structural specs. Grumman gave it the weapons bay and Skunk works added the spyware to the stew. The SR71 can carry a nuclear payload too. There were so many misleading public articles about the thing. I got to see it in person at home in 1988. Just before I briefly left my enlisted military tenure it was on the tarmac at Groom Lake. That was where I talked to another A&P that was servicing the engines on it for a flight over Russia again. That was where I noticed it actually had a fair size weapons bay. For years the Navy kept kept a handful of highly modified F14's and A-6's.
Hey! That thing has an S duct like the L-1011!! Cool design.
I’ve done a lot of research into electric EDF trying to push speed boundaries, and it’s really a game of diminishing returns. Sure I can shove 2 90s and a 12s into a foamie, but that power system weighs more than 5kg, more than the weight of the original aircraft, and you don’t even get the proposed 12kg of thrust, it’s more like 10. In terms of power to weight ratio: 1.5:1 is required for a fast jet, 2:1 is awesome but difficult, 3:1 is probably impossible, and 4:1 is definitely impossible with today’s motor technology. If you’re chasing speed it means one thing: you MUST upgrade to a turbine jet. Be careful man. Chasing speed is a rabbit hole. It’s literally more expensive than drugs.
Very true
Nice. Good luck.
Great job! That looked super smooth. Out of curiosity, what is the cross-sectional area of the outlet compared to the fan-swept-area of the EDF unit? Either way, it looked really good. Maybe mod the design to allow you to get your ideal CG without the need to add weight and go from there. For what it's worth, it looked fast enough!
Looks like "Space Angels" Space ship.
Nice one! 2nd attempt was not nose heavy but a poor throw. I remember an old Starfighter plan and the CG was at the leading edge at the fuselage. Don't underrate the influence of your fuselage in front of the wing. Room for improvement I think is: Rounded intake to avoid flow separation inside, the back of the intake at the vertical stabilizer and you can reduce the diameter of the nozzle to increase the speed of outflow. Lots of testing is needed but fun! Good success!
Thanks. So I added the speed meter in front of the battery and it added 25g to the nose weight. The plane was already very nose heavy. I also think that battery was weak too. Lots of adjustments to be made! The current exhaust diameter is 43.6mm right in the middle of the static and speed thrust for a 50mm. I can adjust it once I get some measurements
I grew up building this, it's all I had from the hell of home
It's ready -- rerun the design for 1.5 kg payload, put a cluster submunition in the nose near the CG, with a centerline detonator rod to airframe nose to trigger the cluster munition (also serves as safety as its absence safes the submunition.), and call the drone printers in Ukraine. Excellent video. You may not approve of making rockets and bombs, but you can save lives. I subscribed.😊
CG too far forward is usually better than CG too far aft. Especially with a delta dart! :)
How about making the nose out of card / Manila cardboard. Also, would fenestrating the fuse for intakes be better than one large intake like that dragwise?
Remove the "counterweight " from the rear, suspend the plane on a pivot point, and use pennies on either side to find the "sweet spot". We use nickles to balance ceiling fans the same way.
REALLY excellent --- seems quite fast ...
Reminiscent of the Fairey Delta 2 - the first aircraft to reach 1000 mph
You might add a Bernoulli Duct on the exhaust nozzle for weight and balance, plus increased airflow.
I can't see it, but it flies!
Fantastic
Good name for it too
Flies nice! If I’m at the field let me check it out! I’m usually over there with Steve. Enjoy!
Thanks! Sounds great!
You should adapt it into an actual flying Battlestar Galactic Viper. Looked great!
That looked sketchy on the launch but once it was in the air it looked to be flying on rails! Cool content by the way and you’ve got my sub as I interested to see how this build goes. Nice job 👍
Thanks! We will definitely have more videos coming. v2 is already printed
@@hotlapkyle fantastic, looking forward to seeing the V2 in action👍👍
That thing looks deadly like a lawn dart, don’t think I’d take my son along on this first flight.
LW PLA is not dangerous. These planes weigh less than 1 kg and they crumple better than foam
You may want to try AX3 it is very helpful on toss
In every way ... its a win win,win. ...and yes...a first fligth will be a piece of café if you chek all the protocols of rc aviations
Nice delta wing!
Beautiful lines of this fighter-jet. But, help me, you fly it with a Spektrum-system? I would highly recommend ELRS and set it up for low latency and a decent range. I am sure you will thank me afterwards.
Not everything will fly with enough thrust. Enough thrust just means you have a fast car you also need that special little thing called lift.. that plane is super badass though.
Name it the Snail.. Good name for a fast plane :)
That glider looks like it's standing still next to the speed demon.
Looks awesome, but now you need to build it way bigger lol
STRAP A MOTOR ON TO A BRICK AND IT’LL FLY TOO!😂🤣🫡
