Thanks for the info guys,how would an O.S. .32sx be in this plane if I lightened it? I want my next plane to be an aerobatic model because I havn't had one for a while but right now I only have my .32. If I can't build this model light and make the 32 work I may go with the GP DAZZLER...looks like a fun one.I was also looking at the tower hobbies .46 for the ultimate because it seems like a powerful motor for the price. who knows maybe I'll just fork out the money for a big gasser pitts Any recommendations on a big pitts kit for say a G-62?
