ok well i have a x1x an what receiver battery type fits in the receiver box? stick or a hump?

oh an i havent done much but i basically stripped out the electronics and in the process of replacing them. so far i got a spektrum SR3300T receiver with all telemetry hooked up mostly. and putting a hitec HS-645MG servo for throttle, and hitec HS-985MG servo for steering. (nothing fancy, sorry cant afford fancy stuff).
