I built a 140 frame quad. It has Readytosky KV 3100 motors on it, with iFlight SucceX Mini F4 V2 35A with VTX Flight Tower Stack. I want to get 3S to start with and move up to 4S. I'm not sure which battery name to get and capacity to get. I know the LED is over kill, I'm waiting for my smaller one to come in
