It is an 80 inch wing <guy I got it from thought 88> with 1162 Square Inches. The manual says 14-16 lbs with a Moki 1.8 or Zenoah 45. So to your point I think I am in the game with the motor I have. <I hope>
Did you see the ugly motor mounts it had on it in the original pictures?
I am not sure what was on in but those motor mounts were heavy.
Yeah I saw those!! LOL
That and the forward ele servo might indicate a tail heavy plane? The bigger motor should help with that!! Have you done the wingload calculations yet? 15 LBS on 80" shouldn't be too bad either depending on the chord width. I believe I would consider a water bottle tank and a light battery system though. Whatever you can do to keep it light.
