1/10 EP Touring Car

Guys,

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 :)
