I have a Thunder Tiger Easy Trainer (61 WS, Wt approx 5.5lbs) that calls for a .40-.46 2-stroke or the TT54 4-Stroke.

I would like to hang a 4-stroke on this and have a Magnum .52 4-stroke and an ASP .61 4-stroke. Will the Mag .52 with an 11x7.7 prop pull this plane with some authority or might I be better off with the ASP .61?

Thanks for any input,
