Thumbs up

It looks great! I've got a TB-03 that I'd like to do something similar with.
Do you have any sketches or pics of the custom chassis parts you made?

As original TB-03 is little too tail heavy, I used new chassis made of G10 with shorty lipo to bring some weight to front..Now it's 50:50 with around 50g more on front I also offset motor to the right for better ballance and narrower chassis. Another mods are:

-diff gears from TRF502X. Combined with 2,5mm screw and thrust bearing, it gives super smooth diff, compared to original
- steering - using XV01 arms, it allows better steering geometry with larger steering lock
-front axle from XV-01 - it works better with modified steering
-ofcourse, long CVA dampers and front CVDs

this is prototype, it still need some mods for future version:
-different motor mount to fit larger spur gear
- moving rear axle to the front for my new 251mm Porsche 911RSR body
-some better steering, but I stil can't think of something better than this
- new shock towers
- gear diff to the rear

What do you think?
