I got my Kougar used from another club member. The airframe is
pushing 20 years of age. It came without the gear doors. And I
have never missed them. I'd leave them off. Just something
you will end up removing later on.

About 4 strokes on a Kougar...dont do it. The Kougar begs
for a screaming wide open 2 stroke. Speed is what its all about.
It will probably fly with a 4 stroker but it just wouldnt be the same.
