I'm converting my old Line Controlled planes to R/C, and I was planning on simply building a larger rudder with a hinged control surface, in addition to the elevators that are already there. However, someone mentioned on the Control Line board that all the planes he converted had aileron and elevator control with a fixed rudder. He didn't elaborate as to why, though.

So basically, I'm curious if I can get away with just building a new rudder. I have no doubt the plane will fly, but how it will fly is another story entirely.

Also, it seems that these line controlled planes are a little nose-heavy. Should I alter the COG at all? How far back from the leading edge of the wing should the balance point be?

Thanks.

Charles.
