So if your gearing is right and your motor isn't broken then other factors play into this "gearing/motor combination", correct? Then assuming everything is working on your RC (i.e. everything that needs to be moving/spinning freely is doing so, etc.), something else is overworking the motor. I feel like the weight would be the major factor here. I'm not an engineer or physicist or mechanic so, I don't know. But, if trying to determine which way to go with the motor, which way would it be? Do you need a higher/lower kv/turn motor?
