Hi Payaso,
maybee its possible to install the "bit" in a 1:87 scaled car. This way is ok to build a personal car or a small van.
But if your project is a truck, I suggest you to use a proportional radio controler in the car. I think, the bit have only "switch" controler (no power- full power) and the most fun of TTTT is drive slowly on offroad layouts.
The bit motors are not powerfull enough for a truck. A small personal car may be ok.
Thr bit batterys are only for the bit-circuits I think. You need 3,6 or 4,8 Volts to power a small rc-truck in the kind of the TTTT
If You need help to build your first TTTT, just feel free to ask here. I dont know any dump question.
best regards
Thorsten
