I've used cables a lot of times, especially where there were angles involved. Sullivan Products makes flexible cable push/pull assemblies in .032, .056 and .063 cable diameters. For a small plane, the .032 should work satisfactorily. If you use a nice large radius, they are almost friction free.
Search Tower Hobbies for part number LXFU94.
I think this link will take you to the correct selections; if not, use the part number above.
