RE: GSP/Chief Katana?
I would think that would be a good combo. If the Zenoah will swing a prop in the 18" range and do it in the 7K+ range than it will be a winner. The additional weight on the nose is a big plus. I have been thinking of a Moki 180 for glow, but I would like to go gas and if I did it would be the new Roto from RC Showcase. Probally the 35. Sounds like a match made in heaven. The Zenoah G 23 and G 26's I've seen all ran good, but were not very strong. It all depends on how you want to fly. If 3D is a desire or at least some then a Zenoah is out of the running. It just is not strong enough. I have seen one with a Moki 180 and the power was unreal. Also was with a RC Showcase 180.
Take it easy,
