So, I have a got a quad with (4)  700KV  motors on it. A  M-NAZA controller with the versatile unit link. I have a Futaba 6 EX  TX  and the  receiver that came with it on board. What type/Amp speed controller  and corresponding Lipo would you suggest for it. This is my first quad minus the little cheap ones I have been training with for the last several months?
