Hi everyone. I foud this post while searching for some info on the 1/4 scale Cub. I plan on using the Cub for research at a university and would like to know how much payload I can put in it. I want to know how much open space there is inside it and how much extra weight you think it could carry with a Saito 1.50 four stroke. Could someone give me measurements on the open space inside? Also, I want to know how much fuel the Cub will hold, how much is standard and how much is pushing it. I want extended duration flight times so anyone with estimates on their flight times would be helpful. Thanks.

Larry
