Anyone see any potential problems?
If you have a shaft mounted spur gear, and run two motors that are on the same motor plate, then mate them up to the same spur gear, while running the motors in opposite directions..... You will have the slowest car ever as it billows smoke. The motors need to go in the same direction, otherwise they would both be pushing against eachother, and result in the car not moving while you quickly smoke all of the electronics in the car.
Also, a dual motor setup is not ideal. Run a single motor/esc setup, with lots of cells to get big power.
Id recommend a Castle 125 amp ESC.... and a NEU motor.
A good buddy of mine, Nic Case has the motor driven land speed record for RC Cars, and used a similar setup in his early speed run cars. Not sure what he is using now.
