ANYTHING BUT THE 1.00 on this plane!!!! I just bought the EF Yak, Hitech 5945's all the way around, a Li-ion battery system for it, and a saito 1.00. THIS PLANE WILL NOT BALANCE WITHOUT ADDING WEIGHT IF YOU GO WITH THE SAITO 1.00 (and were talking battery pack to the firewall and 6 oz. added to the nose kinda weight. I have now replaced the 1.00 with a saito 1.50 and it balances perfect.

This said, it shows how great the 1.00 is. Power to weight you cant really keep up with it however its just too light for this airplane. The Y.S. 1.10 would be the "best motor" but Im no Y.S. guy they are a lot harder to get running right than saitos (to me) and you have to buy that expensive fuel.
