here is one thing to think about, how much do you really need a brushless motor. go a few years back before the brushless motors had really become popular and people were making planes with speed 400 brushed motors and the planes were flying excellent. and then expensive brushless motors came around and all of a sudden it seems like if a plane is powered by a brushed motor it will fall like a rock. so is it really worth paying a ton of money on a rediculously priced brushless and brushless speed control for your plane? it seems like a brushed motor works just as well, but costs less.
