The motor has a max draw of 23 amps and continuous of 19 amps.
You should always have a speed control that has a higher amp rating than the motor being used.
Here is a thought, how many cars would a manufacture sell if they only used a motor that would only allow the car to max out at 50 mph?
And if you tried to drive 55 it would quit or blow up.
You can fly it at half throttle.
Good Luck.
