Just wanted to get some feedback on how well an O.S. FS-40 Surpass would work in a Great Planes Slowpoke 40.

On the GP website the Slowpoke 40 has an engine range that includes at the low end a .40 four-stroke, but the plans call for between a .48 and .52 four-stroke.

To me it seems that a .40 four will work but may be a bit lacking in certain situations. But since I'm just looking for a nice slow follow on to a high wing trainer (an CG Eagle 2) I don't think it will be a problem for me. That is, I really don't need anything too fast or overpowered.

Any opinions?

Thanks
