Depending on what motors you use, brushless drive should be as fast and responsive as a similar sized brushed motor. You probably want far more powerful motors than the 540 sized ones I use in Mr Mangle. Look around for 1/8 scale motors like this: http://www.hobbyking.com/hobbyking/s...or_1900KV.html



I haven't used that exact motor but its the size I would expect to get a heap of torque from in a featherweight.
