This thing is a 1/10 scale electric 4wd touring car. Not fully, but the most parts are 3D printed. The not printed parts are from a cheap Tamiya TT-01, you can buy them from ebay for a few dollars. The suspension geometry is very similar to T.O.P Scythe, or HB Cyclone. The goal of design this stuff is making a better adjustable chassis than a TT01, but keeping the robust and cheap drive train.

It have a highly adjustable suspension. You can adjust:

  • Front and rear toe in-out (with one screw release/wheel)
  • Front and rear camber
  • Front and rear shock absorber position
  • Front and rear roll center
  • Front caster with different C hubs
  • Ackermann

If you want to build this RC car you will need the following parts:

  • Tamiya TT01 ball bearing set
  • Tamiya TT01 differental gears (2x)
  • Tamiya TT01 drive shaft
  • Tamiya TT01 spur gears (58/55T)
  • HPI Sprint 2 swing shaft (2 pairs)
  • Tamiya TRF shock absorbers (or something similar)
  • Universal connecting rods (3 pairs)
  • A handful of M3 screws, and ball studs :) (I will count)
  • Yokomo (#ZS-016P) Body Mount Post (F/R 2each)

Known bugs:

I have printed a prototype from PLA, and ran out some battery packs. The conclusion is the following:

  • Little bit flexible chassis
  • Weak differential outs (a 13,5 motor can break easily on corner exit)
  • Sensitive suspension parts, easy to break.
  • Recommended to using a heat isolator between the motor and the motor mount.

I have lost my inspirations about this project. If you want to help to test or develop this stuff I will share the 3d files with pleasure. Let's carve a good 3D printed touring car :)

Really cool design. Impressive actually.
Have you tried or considered using Carbonfill instead of just normal PLA?

It may add up in resistance compared to normal PLA with no much extra weight.


It was planned, i have bougth an xtcf20 spool, but never tried :)

Good afternoon, I could tell the wheelbase of the car, because I have a body and I do not know if it would serve or not
Thank you


Same as TT-01. 257mm

Have you shared the files of the front and rear differentials that come out in the picture?
Thank you

They are not printed. Came out from a TT-01.

Can you release files other than stl? for modifications? This is awesome work, just want to tweak things and stl is rough for that. Thanks

could i use this to build a 1/10 drifter?

Of coure, but you should lock the rear diff.

nice! can you make the 3d files available?? I'm trying to turn my tt01 into a rally car.

Nice! Do you have a parts list for the reminder of the stuff I'll need to finish it?

I don't have a partlist yet. I'll make one soon.

hey! i need dat sweet sweet parts list! -Please :D
