It has a Deans female adapter attached.
Using two standard Futaba S3004 servos and I am using the ESC's own BEC to power your RX and servos?
Vista booklet: Motor run time and flight time can be extended by using batteries with higher capacity, but do not use batteries with a higher voltage (more cells) as they will not fit in the model.
