I have the 880kv arducopter motors, an rctimer esc (30C I think) and a 8000mah 30C battery. Prior to upgrading the battery (from 2 2650mah), my quad was flying ok. Even when I used the new battery everything was ok. Then one day, arming the copter and increasing the throttle to just below take off, smoke developed from the left esc. Smelling it confirmed the source of the smoke :)
Question: is there a general rule on what C rating of the motor, the esc and the battery should be? I mean should the esc be limited to 20C (reflecting what's available at the store) or I can go higher. If my battery is 35C, should my esc be higher than that C rating? Any pointers will be appreciated and please don't limit your reply to my two sample questions and feel free to educate me on the proper way of mixing it up the motor, esc and battery C ratings.
