New member, need some help pls

[Hugh Hanson]

hi all ,
I have just started flying rc helicopters in the last month or so. I bought a trex 450 plus and crashed it fairly fast so i went out and got my self Phoenix-4 flight sim and a blade mCPX BL to practice on.

Anyway, i got a spare EXTREME 550mah 3.7v 30c lipo for the blade but it only has a 2 pin plug on the end and the blade has a 3 pin connetor, is there a way to convert it so the battery will work.

cheers
Hugh

The new mcpx bl runs on 7.4 two cell battery's
so 550 single cell won't work !
