Recommend 4 stroke for GP Cosmic Wind Minnow

Just bought a Great Planes Cosmic Minnow (60 size 2C, 90 size 4C). Ideally I would like to get an engine that would fit in the cowl without lots of engine sticking out. They recommend an OS 91 4 stroke.

I am leaning towards a Saito FA82A or FA91S Not much power difference and the 82 might fit without cutting for the valve covers. They are a bit lighter than OS and magnum alternatives.

Any recommendations on an engine that would work with minimal cowl cutting?

Saito 1.25 golden knight is my suggestion. you'll need a bigger 4-stroke thatn a 2-stroke to equal power, 4-strokes have about 1/3 less power than 2-strokes.

I do fly mine with a Satio FA 125 and a APC 13x13 Racing prop from tower hobbies. Engine mounted horzontal. Vertical performance and speed good.
