I can tell you a 61fx is under powered a 91 for4 stroke should be just right.flew mine with a 61.needs more power, i love saitos 115 would be my engine of choice

A .61 two-stroke and a .91 four-stroke are the same power. Other than pulling a large diameter, low pitched prop for ultra good takeoff power, but reduced top speed once airborne, the .91 four-stroke has no power advantage over the .61 two-stroke.

If you're not afraid to fix your own engines, go to the Hobby King website and gaze at the prices of ASP engines (Magnum USA parts will fit). There, you can buy an ASP 1.08 two-stroke for less than $100 plus shipping or an ASP four-stroke .91 for not much more than $100 plus shipping. Both are great engines.
