I am in the process of converting this airframe to a gyroplane like the "littlewing" by Ron Herron.
I need help to decide what size/weight engine i can hang on this Fuselage.
I am trying to determine which model this is a copy of, i will include a couple of pictures of the airframe.
It looks like a combination of an Avid Flyer/kitfox 3 and is primarily constructed 1/2 4130 except the wing spar carry tubes and the two main cross tubes in the floor.
I plan on changing the front spar tubes to 1" X .048 and the forward down tubes too 5/8' X .048 tubing.
according to Ron i will need 100hp for reasonable performance and am leaning toward a 110hp corvair conversion but it is 225 lbs and i want to make sure fuselage will carry that weight.
I am hoping that some of the more experienced/knowledgeable people will chime in
