I'm expecting a hand slap for this but.......................I have said over and over that these full scale theory papers have very little bearing on our models. We have a fraction of the wing loading, twice the power, a fraction of thier drag and so on. It is unrealalistic to expect all this lititure on full scale to work on our models. For the life of me I can't figure out how a person can take the opinion of somone who wrote a book on full scale theory but has never flown a model over somone who has 33 years of r/c experience. Just seems like apples and oranges to me.
Models obey the same laws of aerodynamics as full size planes, they fly in the same air!. models being smaller and slower flying do have some slight differences due to Re effects but the basic rules are the same. Your reference to flying for 33 years is interesting.
I'll give you an analogy; my mom has been driving cars for about45 years but she doesn't have a clue how they work or what goes onunder the bonnet. if i was seeking advice on how car engines work or how to diagnose an engine problemi would value the words of a qualifiedauto engineer (who didn't drive) overmy moms45 years ofdriving experience any day.
Of course in the ideal world you would find someone who had both practical experience and a good grasp of the theory, these things are not mutually exclusive!

Well Steve, like I said I expected this type of response. Your anology is interesting. Maybe I should have been more specific. In that 33 years I have designed and flown models in IMAC Pattern, Sailplnes, helicopters and pylon. In all cases I have risen to the top level from a regional standpoint. Except pattern as this really is my first season but then again I started in the advanced class. I dont not mention this to simply blow my own horn but to point out that in order to accomplish this one has to know how to set up an airplane to fly correctly. Nothing is carved in stone here. When I advise someone here it is because I have at some time experienced the same issue and throw out what has worked for me. As far as the OP is concerned, It would be nice if he were to let us know exactly what airplane he has and take some measurements of both and post what he finds. I'm still convinced that both models do not have the same incidence angles.
