  • why dont you use this in your trial trucks?

  • @pnelego Because it can't handle that much torque.

  • Would it still work with a XL motor or not?

  • @Eddo1998 It works with any motor.

  • Is it possible to replace the dark grey part in the end?

  • @jhsevs Not really.

  • @Drspeedstackingguy its because the grey peice is a differental. so it moves when under

    preasure. all he did was converted that force to that large lever to shift gears.

  • Ha, good gearbox and better music :-p

  • Amazing work!!!!!!!!!!!!!

  • i make it with a xl motor and its working

  • i am still so confused, is it that the grey part near the end connects the gear with the wheel.( but doesnt move) but if the wheel is slowed, the moving gears behind it, turn it ( the grey piece) in a way to change gears? plz reply !!!!!!!
