What Action site?
Also, I flew the Seagull Yak with a Zenoah G20EI(almost the same plane), which made the plane heavy and it did fly, just did not glide well with all the extra weight. I also flew the plane with an O.S. 120 AX and it flew fine, so I do not understand the previous comment
At the high end of the weight, your wing volume loading is >14, at the low end it is still >12. This will tend to be a lead sled, if everything is correctly set like CG etc. it should be flyable but will require excessive speed for takeoff and landings and will not fly well. A wing volume loading in excess of 12 is not a model I'd be comfortable with.
Sounds like you are saying that the plane will not fly with any of the recommended engines . I am planning on an O.S. 120 AX or Saito 125 at this point.
I did not say it will not fly, I said it will fly but be very unforginving in all aspects. It will be easy to stall unitentionally like on that downwind turn on landing and will use a large amount of runway for both takeoff and landing.
