Hello all. I'm trying to go brushless with my Dragonfly. Do i need to have both main motor and tail motor to be brushless or can i go with just the main motor? Also I have an E-Sky receiver and gyro/mixer. Will this be able to work with a brushless set up? If so, what would be the best way to set it up. I've heard that brushless is the best way to go. Thanks for any input.
