I picked up a 3 cell lipo. It made a world of difference. I'd like to try a brushless on it. Maybe later. I need to find out how they are mounted, which motor would work well and which speed controller. I've purchased, built and flown two electrics since my first post to this forum. I'm getting closer to wanting to convert all my planes to electric. Oh, and the global wattage battery I listed above was junk. I tried a great planes nimh battery, same size and amperage and it was much better than the global battery.
