I know a lot of us use the balance plug on our battery packs to get our FPV power. When I've needed to plug into that, I've always used a header and was just really careful not to plug it in the wrong way and blow everything up. A much better solution is to have the right connector, but I wasn't sure where to get that. I just ran into the solution on HobbyPartz. They have a package of five male/female cables for just $2.05. I added them to my last order to see if they were what I thought they were. Just what the doctor ordered! You can find them at: http://www.hobbypartz.com/79p-10115.html ...Tiger
