Can I FIX this 3D Printed Airliner after BIG CRASH

[@andygibson6196]

I did not realize how *recent* this was (as of today under 2 months); you are way more diligent and patient with this stuff than I could be. As Torboli noted, you could easily (LOL) add a torsion mechanism to the nose wheel to let it pivot up a little when it hits and reduce the chance of losing control on taxi. This is some GREAT work, Troy.

[@jimhansen5395]

Rubber wheels would be much better for that rough surface. Also, I think you had some cold solder joints around the six minute mark. Otherwise, that's a really cool project, and it looked GREAT in the air.

use flux when you solder at 6.08 ish the joints don't look like they flow very well. neat stuff otherwise.

just don't use lead free solder... lead free is brittle and requires good technique and a good soldering station.

Honestly, you need to find a smoother airfield, seeing you subjecting your finely-printed models to this rough terrain gives me the creeps. I guess it also doesn't help much that you're printing your tires with the same hard filament as the rest of the plane. Maybe you could use flexible filament for that, or (even better), use real rubber tires.

[@aymenallan8832]

Nic

[@BladeScraper]

Nice job! I would recommend creating a receiver battery harness with two or even three servo connectors/cables instead of just one. Servo connectors are only rated to around 3 amps, and those tiny wires aren't rated to much more. As many servos as you have you will likely see quite a bit of voltage drop through those small wires and single connector. While it would probably be fine, redundancy is a very good thing to have. I use receiver batteries on my RC helicopters and always use at least 2 wires from the receiver pack if not three.

[@qazatqazah]

Truly amazing build. Just two thoughts I have: 1) The runway is very rough. I would love to see a smoother takeoff and landing of this plane on a better runway. 2) How awesome would it be to have a camera (or even better: multiple cameras) in that plane, and then fly it with the pilot's view using VR-goggles, and make nice drone footage with it? I understand that would add a bunch of electronics, which means extra work and would add to the budget needed; but the plane is easily large enough to hold such wonderful extra's.

[@SpinStar1956]

Very happy to see you rebuild it. I'm pleased you are now using a totally separate system for the RX and servos. It is usually the high-power stuff that will fail before the low-power stuff! And, I see so many ESC's either have a main MOSFET failure or the darn regulator for the RX--sometimes frying the RX because the regulator shorted! One way or another the RX loses power and you lose the ship! Also, there is an old 'Scratch-Builders' saying: "Any part you can salvage, is a part you do not have to rebuild!" I have made some miraculous repairs with about the only penalty being a bit more weight from the glue or additional supports--but I've never had it be detrimental to the flight characteristics. BRAVO--You're a good man Charlie-Brown!

[@charlesbeshaw9843]

Great video, One suggestion about wire, are you using wire with high temperature insulation such as Silicon or Teflon? Then even if the wire overheats as long as the insulation doesn't melt the wires can't short together, it's a better safety factor. There are high temp woven sleeves that go over the wires also.

[@MarcStollmeyer]

At a 1.6m wingspan this is 1:21.25 scale, and at 3.6kg this is equivalent to a real A321 taking off at 34.5 metric tons, about 10 tons lighter than the empty takeoff configuration.

[@fsniper1939]

I remember watching your titanic videos when i was like i think 6 or 5

[@Vaeloron]

Glad to see you rebuilt it. The long ESC power leads are still a concern but I have only known it to cause an issue on one of my builds when I did it on a large drone. On that drone I resolved it by extending the leads from the ESC to the motor instead of the battery lead. Grats on the successful maiden.

[@Pastorkarlman]

Wow, I'm still amazed that you designed this beautiful plane from scratch in Fusion360. That is a feat in itself. Great video of the build, crash, and successful 2nd maiden. Would love to see you do some more full designs of other iconic aircraft. I'm sure you've learned a ton about what makes a good build and design from Eclipson, to Planeprint, to 3Dlabprint designs. Keep up the great work. I've learned a ton from your videos. Currently building the PP Eagle and Snowy Owl, as well as the Eclipson Pitts.

[@ianholt5527]

Great video I've ordered my 1st 3D printer after watching lots of your channel a Anycubic Vyper.Been into rc flying for many years and I would recommend a watt meter for your tool box,it saved one of my models when I put an over sized prop on pulling over 100 amps on a 80 amp esc.

[@EricAero]

I'm so glad you came over the crash and rebuilt it. I'm also glad you used the auxiliairy battery for reception ! Great job !

[@SupernovaSpence]

I might suggest some split flaps for a lower landing speed as well as something to absorb the landing shock. I'd use a 3d printed trailing arm suspension with some rubber bands as spring force and a 3d printed rubber bumper for dampening.

This flew MUCH better than your DC3. Hate your field… that makes it very hard on the plane, all that rattling on those horrible old cracks in the dirt ….

Thanks for your generosity in sharing your experiences. Bravo.

[@jasonhurdlow6607]

Love how that thing flies! Great job, and also good job on getting it back in the air and utilizing feedback from your last video. Thinking you need to have that landing gear be articulating and have some form of suspension though. That, and maybe run a Zamboni over that desert floor! :D

[@liavhe]

Retractable gears will reduce a lot of drag during flight, and increase your potential flight time. Adding flaps will help you land much slower, but in the meantime try pull up a little bit more before touch down. So far looks amazing! Looking forward to your next video

[@MikkoRantalainen]

Does your radio setup support having separate power source and radio systems for the control surfaces and another set of radio and batteries for the engines? That way you could fly the plane controlled down even if the battery for the engines fails. And use fuses rated for your wiring and engines (whichever is lower). Another option is to have two sets of control surfaces and run redundant radio system for the control surfaces. Even if one radio system fails, you still have half the control surfaces available.

[@kilometer500]

I was wondering where are the fuses. Are none used? Very strange this method. Electronics basics say, always use a fuse. Like you say Mikko.👍

[@afterburnerrc6333]

Hey great job! Glad you stuck with it and printed another as it really has a presence in the air. I was curious in regards to your print farm. What’s your favorite printer? I have a Prusa and CR4 but looking for a good nylon capable printer.

[@generessler6282]

Hey man. Beautiful mechanical design and craftsmanship! But a tip... Don't hold connections with your hands while waiting for solder to cool. No matter now steady you are, you'll move a bit. That's enough for the solder crystalize as it solidifies. That's a future connection failure waiting to happen. Get or make yourself a "third hand" to hold what you're soldering perfectly still.

[@maxdragon91]

Another awesome video! Great to see the liner in the air and I'm sure I'll be purchasing the STL before long. The liner could use some flaps, in my opinion, to help slow the landings. Your 3D printing future is looking busy.

[@chairmankaga2821]

Maybe you need some flaps. That landing was pretty hot. Amazing build quality to hold together under the stress of that landing.

[@wdibert]

Excellent re-build. Amazing the work, you can perform. Being on a dry lake bed is very rough on your gear. If the wheels are to scale you may want to go a size or two bigger given the conditions of the road bed. Looks matter but so does function too. Stay well.

[@curtisfoster540]

It would probably be enough to be in awe of the engineering of this model from scratch, but to recover from such a crash so quickly speaks so much more! This is so, so motivating! Well done!!! I'd love to see an implementation of this with simple shocks and rubber tires if continued to fly on this dried lake though :)

Like his comment if you are here in 2024

[@dr_jaymz]

Great to see it back. That's the beauty of being able to print another. That surface is really rough, those ridges are a 2 feet deep to scale. Some shock absorbance is essential.. A sliding fit with foam blocks or something keeps it simple and light and may help.

[@davidtheswedishtechguy]

Soo cool, I've been flying edf for years and jets😊 always used 3D printing for it too and thought about 3D print a hole plane😊 Btw, have you thought about using carbon fibre rods in the fuselage instead to hold it all together ?🤔 then it would be easier to replace sections and it may be more rigid

[@hansdeutsch2602]

Next time, use a separate dual power supply for the receiver and servos.

[@cmtetaboaco]

That was not a landing, was a second crash similar to the first LOL

[@Kang884]

it’s pretty hard to land in a fast speed and a rough runway

[@ArrowProds]

From what I could see the landing gear was still plastic? Perhaps if you could get some rubber and some way of shock absorption, flaps etc... But for what you have, it's still a really impressive model aircraft which flies with perfection, and honestly it's still great either way. Keep up the good work!

This is the reason why I'm considering on getting back into RC Flying again. If you crash you can just reprint new parts for not much money. In the past you'd spend weeks building your plane then after 1 or 2 flights you crash. You then put out another $200-$500 for new parts and spend another couple weeks rebuilding your plane. Once its rebuilt you take it for a few flights and then you crash and then repeat the process all over again.

[@mybestcarcom]

Such a nice plane... After analysis of your prior crash. If you included added some NACA ducts in the body with some air flow tubes to the front to keep the heat out of the body and the air could exit from the APU exhaust port. Then if your flying and see a smoke trail you could land immediately. Also might cool the battery and wiring some. Some under wing stol flaps would be nice also to slow the landing speed and reduce gear stress.

[@EsAndreiAviacion]

[@olliec7609]

[@christopherleveck6835]

Isolating the receiver ELECTRICALLY is a good idea. But if the issue is a problem with the main flight battery, PHYSICALLY isolating the receiver out from under the potential fail point, like the main battery overheating and catching on fire, is going to take out the receiver anyway.... I have several large 3d printed aircraft. I have a wood tray that keeps the battery away from the walls of the fuse and I have a simple duct, using toilet paper rolls usually, that allows cool air to flow over the battery and out of the airplane. I also use a temp sensor on the motors and batteries so I can tell if there is a problem right away. I used to like using the toilet paper tubes for a battery tray. If there was a fire, there was one time, the paper from the tube starts to smoke right away, so you at least know something is going wrong but it also works as tinder to start a fire.... So I use temp sensors. Even if your radio won't support one, the sensors are SUPER cheap. Like 40 for 7 bucks... You can make a simple circuit to turn on a buzzer or flash some LEDs or something to let you know.

[@jasonhurdlow6607]

I agree having air ducting to cool the electronics would be a good idea. The question is how do you do that on a model like this and not ruin the scale appearance by having holes cut in it? Some sort of mesh panels perhaps?

[@christopherleveck6835]

@@jasonhurdlow6607 get creative...on this model I'd go a little buts maybe but to keep the lines I might use the nose landing gear bay to cool the electronics, the engine nacelles to cool the esc's assuming they are mounted above or near the motors or the main gear if they are close. You can use the windows by keeping any interior visible behind the openings black. If you are going to duct the area then just make sure to paint the inside of them. I made a flip down widescreen on a model with a light rubber band to pull it shut on the ground, but forward movement blew it down/open. I usually duct all the existing hot air into each other and out the back. In this case the scale aircraft have an EPU which is a small jet engine in the tail used for extra power and starting engines, etc. If you tie them all together the hot air will actually work together to pull cool air in as it exits out the back. But be careful, you can cause yourself some trouble over thinking and create a problem where there wasn't one. I made a hole in the front and the hole in the back was arranged exiting out the sides which created a weird venturi effect that slowed the airplane down and heated everything up. I've used a small EDF motor and the excuse to smoke the odd rare cigar to push and pull air through various parts of the airplane. It makes it super obvious if your plan is working or not.

[@scottconnors7901]

Winner never quit, quiters never win. Great comeback and flight. We all learn some kind of way. Keep up the great work.

[@MikkoRantalainen]

Very good video! It nicely underlines how you shouldn't assume that the first assumed cause for the crash may not be correct root cause. From the maiden flight video I assumed that the diagnosis that battery failed and caused the crash was the correct one. The explanation that wiring overheated and shorted actually makes more sense.

[@rp3618]

I am sure you thought of this? Is it possible you can place strategic elastomeres at critical joints, aerodynamic surface joints and shock for landing gear as well as larger wheels with lower air pressure to absorb the rough launches? I realize there will be a weight add yet there are near zero weight elastomere material to do this. Another person suggested mitigating battery temps via liquid - good idea. Try honeycomb as all mounting areas - distribute heat.

[@0utcast]

you would need some sort of shock absorbing feature or really small inflatable tires if they exist. or you need a smooth takeoff/landing runway. a dry lakebed isnt nearly smooth enough too much vibration etc. flaps would be good too then you could come in real slow and easy.
