RE: 6v or 4.8v reciever battery?
Ok thanks guys.
Whats your opinion on smart fly? I'm looking at the Power Expander sport. I'm a little confused on everything about them. Someone at my club basically says I can hook 2 6v batteries into the smart fly, and if one battery fails, I have the other battery. I don't see what else a smart fly is good for. It may just be another piece of electronics that could fail, instead of the battery failing.
Thanks
