For .60 size planes, I'd get the AR500, AR6200, or AR7000, depending on how many channels you need (5, 6, and 7 respectively).
I put a 3S LiPo battery in my DX7, so now it stays charged and ready to go, and recharges are very infrequent.
How do you handle the extra power from the Lipo. I know fully charged it gets well over 12v. Don't want to burn something out of my DX-7
