Well, just found a $30 brushless on hobby lobby and the greatplanes brushless esc would probably work great for it. Thats a $60 brushless system, WOW. I understand i will have less flight time and less performance due to weight with a Nimh battery. Is it totally not going to work if i use a Nimh? With the brushless system and 7cell 730 nimh, what kinds of flight times will i get? thanks
