Default Plan Modifications



Here is the plans of the wing I am scratch building. I got them enlarged and was looking at them last night, I started wondering if this plane was worth making. I started doing some research on it, I found one built, and the guy who built it says it flies great, so I will take his word on it. The plans were published in 1980 in RC Mag, so there is some credibility to them. I am wondering why the designer did what he did, an example.... why the use of all the bellcranks, why not use servos. So my question is are these designs so strict you cant make any changes to them. I am sure the guy took the time to figure the weights and balances of the plane, maybe not, this being my first scratch build, I really don"t know if I can make modifications, like moving servos. I don't think it will effect the CG.



While I am here, I started making a few wing ribs last night, I was cutting six at a time. I took the paper stencil, glued it to the balsa sheet, then glued six sheets to it. I tried several different glues, I watered down some white elmers, tried one of my grand kids glue sticks, I really didn't have much luck separating them I was able to get them a part, but was a *****. I searched it on line, and someone mentioned a 3m product, spray adhesive, I think M85. i couldn't find it at lowe's, wal mart, home depot. So what do you use to do this, I hope its just a mater of maybe using too much glue, I can't see cutting 1 rib at a time, when 30 of them are the same size.

Thanks for looking and taking the time to answer.
