These are only guidelines; if you don't know how to pick the right motor, please consult OSE first or other members of the RC Fast electric boating community, either at a local club or on our OSE Forums. * It is important to note that the "Max Amps" value represents the maximum recommended operating current for the motor. It does not indicate the maximum current the motor can draw. For instance, the 650kv motor has a "Max Amp" rating of 205. This means the motor should not be operated at a current exceeding 205 amps. However, this does not imply that a 200-amp ESC will be compatible with the motor. Instead, the user must select a propeller or gearing that prevents the motor from exceeding its "Max Amp" rating. It is important to note that the 205-amp motor can exceed the 205-amp limit for a short period when pushed beyond its limits.
