how hard was to build the slow poke. I read one of the building descriptions and it didn't sound easy.
I like 60 and 60 size airplanes so I might just get rid of this engine...
Our field owner has a 25FX on his TCraft and it is a great match. The 25 two stroke probably has power output between a 30 and 40 four stroke.
The one comment about an "underpowered" model is using an engine with less power than your 25 two stroke.
I built the G.P. T-Craft and powered with the O.S. 26 FS 4 stroke. IMO the engine doesn't have enough power to fly the plane well.
