3D Printing RC Models

[PFarm]

Is anyone in here into printing RC models? Found the Heavy wrecker model though I'd give it a go. Assembly going to be like putting a puzzle together with little to no direction on how to assemble it. I like puzzles LOL.

This will be my go-to for assembly

 That thing is a monster! I look forward to updates.

I have built a couple of 3D Printed RC. My son and I built a pair of OpenRC F1 cars; I kind of want to go back and reprint to the newest spec. I also built a Tarmo4 truggy. I think I have a couple old threads around here somewhere on those.

I printed a few cars but found that anything that moves is not going to last.  I had decent results with body parts or the frame.

Drive shafts are a no-go

They need to be beefier. The Tarmo4 ones are probably 2-3x as thick as those; it also uses big TPU intermediate shafts from the gearbox to the diffs. IIRC, that model is intended to use metal ones. The main thing I keep killing--aside from crash damage--is indeed gears; both on the OpenRC F1 and the Tarmo. I have learned to print up a bunch to have spares handy.

More parts printed, when the Trident is complete it will assist in printing parts for this project (a lot of parts). Need to order more M3 nuts and M3X8 screws. Got some Esun Silk silver PLA for the chrome parts. It going to be a fun project putting it all together. Esun ASA black, Esun ABS Orange, Matter3D ABS Dark Grey.

Love the truck, nice job.  I am thinking of printing RC model airplanes with my Voron 2.4 350.  Looking forward to your progress.

Before moving to mainly 5”-10” I was printing and flying tons of Micro and Whoop frames. Anything bigger didn’t survive a single crash. FPV got me into printing.

@madmike46 I've got some Polymaker PLA LW to print a few model planes as well. @ArkansasFPV Nice collection!

Even on small Micro or whoop frames PLA had too much flex. 1” and smaller props were enough to flex the frames.
 

This is a few more of my collection. I have more in the car and attic. , I am a bit of an addict. The ones on the walls don’t get out a ton anymore. I have found about 12 frames for all different conditions that stay in the car so I am always ready to fly.

@ArkansasFPV Which filament do you use?

I really like HatchBox ABS. It sticks and  prints well. With smaller, lighter builds it holds up to crashes.

Started assembling some of the pieces.

Looking good - like the color

Assembling tires today as the rims come off the printer.

Did you print the tires?  What filament did you use?

[PFarm]

@madmike46 Yes printed with ABS no TPU. More progress today on the assembly of printed parts.

 

[madmike46]

That is looking great PFarm.  I showed this to my Buddy that owns the local towing company, I think he has downloaded the files.  Are you going to go full RC on it?

[PFarm]

@madmike46 No going to be a model sitting on a shelf.

No fun in that :).  I shouldn't talk I have a DC3 with 85 inch wingspan that has only had one flight and a Norseman with 85 inch wingspan that has 12 flights.  Norseman is 5 years old now and the DC-3 is 3 years old.

It's a cool hobby, but can be pretty nerve racking when you have a 1,000 hours in thebuild.

More progress on the assembly it is almost there just the rear tow bar and outriggers left.
