I have one running a Zenoah G-74 with a Bolly wooden 24x8 prop, it will fly IMAC no problem but it really is low on the power side, needs a motor that can swing a 26x10 easliy and then it would be great. I am using Hitech 5925 servos throughout with a powerbox and JR PPM reciever. It general flying characteristics is fantastic and I enjoy flying it. A really good build.
