Are any of you guys running lipo batteries in your Futaba Tx? If so what voltage and capacity? Just noticed that the system I want comes with a 9.6v 600mah nihm. I dont know how long that'll last me if I'm flying all day. Right now I have enough lipo to last me a little over an hour of straight running and I dont want my Tx to start dying on me. If you guys know where I can get a nice lipo for the Tx please post a link. Also will 11.1v kill the Tx? Thanks, Joe
