RE: Using Lipo For My Futaba 9C
I just purchased a 2500mah lipo from Commonsense. The best $56 US I have spent. The only thing is you will need to buy and solder on a connector for the battery. At the same time get a wiring setup to charge it. I use deans connectors on my batteries so I put together a deans female on one end and a futaba servo extension female on the other end. As for the battery, very long run time, I'm going on a weekend now with about 4 hours and still at 11.0v showing in the display.
