the VFC scar was designed to have wireless breakdown... the wires from the gearbox end at the back of the receiver. If you find the stock adapter, you will need to drill holes (or a large hole) in your receiver and rewire your gearbox to a more conventional wiring setup, which is not hard.
So either drill holes large enough to pass bullet connectors through to adapt to the shortened harness on the gearbox, or drill 1 big hole to pass a deans plug through.
I futz with V2s, V3s and V6s. I could be wrong... but probably, most likely not, as far as I know.
