RE: motor problems
 

Several possibilities:
1. Bad motor.
2. Motor is connected to the battery end of the ESC.
3. Battery polarity is reversed.
4. Bad ESC.

On some escs you have to retrun the throttle sitck to the off position after the initial beep.

RE: motor problems
 

The motor you are using sounds like a brushed can motor, could you post a link to the speed controller you are using, I could not find a listing for the model you mentioned. Are you sure the ESC is for a brushed motor? you can't use a brushless controller for a brushed motor.
