I removed the boosters, and cases for 3d a long time ago.. When all they had was Optima7's. it cuts the weight by more than half! Been flying the A9, and hitecs 2.4g from day One. Hitec actually says its fine. I don't fly very far away anyhow..
I power the RX from 4s power with the spc(it can take something like 30v?) and the servos/retract with the BEC. A bit redundant but a servo can't pull down the RX, and optima7's are power hungry!
I fly fast, and make fast transitions, in the past I've found the switching BEC regulated, gives the best power to the servos, with no fade. This is going to be a different type of jug
. We're taking bets to see if I can torque roll it with the flaps ganged as ailerons..
I also bet someone I can do the snake with it!
I'm going for light with a neutral CG..
