I’m currently on track for 11.5 pounds dry.
I’m sort of using my Seagull SuperStar as a comparison. It’s just about the same size. My SuperStar is just a hair over 12 pounds dry. Is stupidly over powered with a Saito 180, and doesn’t want to land.
I haven’t determined the actual wing loading on the SuperStar, based on its flight performance at its current weight, I’m comfortable that I should get acceptable performance with the Extra in that weight range.
Once the building is done and I have a better idea of how much weight I’ll need to balance, I’ll try to find a motor that’s close so additional weight is not required. (My degree is in engineering)
