Thank you. Out the bottom it is! > > Those wings are really nice. (I want I want I want I WANT) I thought the same thing and I have been ready for a new plane for a while now.

I cut my cores at 6" which makes my thickness just over 1/2". That still leaves my .47" th. servo hanging out the back. On this version I am going with outboard servos. I am already committed. I have been round and round with moving servos inboard for CG purposes, cable linkages, torque rods, etc and I just decided to go the most direct route. Ie; outboard servos. I figure that if I like the way it flys I will tweak it and build another one. :^) Chris RCSE-List facilities provided by Model Airplane News.
