RE: 40% 260 on a Diet
interesting project!! i will definitely enjoy seeing your progress!!
i tend to agree with albert and wayne also.
you might want to look at the evolution 116 engine from horizon hobby. its about 1 pound heavier than the DA, which will help with balance. also it has more power than the DA, which will help with power and turn a bigger prop (30x10 i think). AND on top of those, its the same price!!
