I found at Hobby people a 4.8 2200mAh battery for 13 bucks that should last all day in the ignition. Most 6volt batterys are over that so I just don't want to take a chance of letting the smoke out of the box. But I am going to run two 6 volt batterys for the sevos for sure. One reg and one for back up. What do you guys think of this for a 50cc plane? http://www.hobbycity.com/hobbycity/s...idProduct=8355
