start search with the 3 wires from esc to motor...sounds like a loose connection. one more thing........welcome to wattflyer mike. this is a a hobby of many things that can go wrong and probably will. my tranmitter of 4 years just went on the fritz today pretty much squashing any flying till my new module arrives from hk[china]. it's the first time i'v ever paid for "ems" shipping....thats how much i want to get back to flying...lol.
narrow is the place to land...wide is the space to crash....choose the narrow way!
disconnect the 3 wires from the motor and esc, use a volt ohm meter and check for equal continuity on the motors 3 wires, testing 2 wires at a time, there should not be any continuity from the motor wires to the motor metal case, pull on all the connectors on the esc and motor, sometimes a wire will break inside the plastic wire covering at the connectors, hope that helps, Chellie
you can get a cheapy volt ohm meter at Harbor freight tools for about $5.00 if your in the USA
