I have the winwing adapter but need the stick to be just a bit longer. I made my own adapter and extention to go from vp rhino to winwing grip but now I have to make/buy a plug for the wiring. I see that the rhino base uses a 5pin female and the winwing uses a 6pin male plug. What does 6th pin do, do i need it. I have a short 6pin to 6pin, can I pull the 6th pin out and use that cable?
