Sorry to ask if its a dumb question.Its my first electric car,but thanks in
advance.
the bd7 is very picky on spur gear. so far only the Panaracer brand fits because it's the official brand. there might be other brands but i haven't figure out yet.
the car comes with a 116 tooth 64 pitch gear which is too big for 21.5 motor. you'll need to buy a 92-96 tooth spur. preferably a 92 tooth if you can find it. 96 is more popular though and most hobby shop carries it.
your FDR will probably range from 3.4 to 3.8. so just get the appropriate pinion gears.
for spare parts, just get the arms, c-hubs, steering knuckles and bottom king pin screws. it's a somewhat durable car despite popular believes. nothing else should break in a small to medium crash.
