i use an 8 cell nickel metal batt. with 1300 mah. on my slow stick.
it flys great. CG is very important with this plane and also the
WIND FACTOR has to be added in.(this plane doesn't take wind well) i think the ss is the plane to have. its slow and ez to control.
i moved my control horn out on my elevator so i could get more throw. i have about 2 in. off center of throw both ways. in wind you need every bit of it.
