I got a Titan 12t motor and xl5 esc I removed old msc . My reciever and 3 plug in slots where 1 servo plugs in for steering then another one plugs in for throttle then another coming from out side of msc labeled battery . I installed xl5 but now only have 1 wire from steering servo then the one coming from esc that I plugged into batt plug on reciever . When powered on I have steering but no power ( or control) over motor . Could someone explain to me what I need to do here thanks ...
