Yours must have come from a different manufacturer then mine as mine had a sheeted foam wing. There weren't any ribs. I bashed mine quite a bit and wound up with dual elevator servos, pull pull rudder, dual aileron servo's a Canopy from a Black Horse models Extra (40 size) and a Saito 1.20 under the hood. The plane flew like a dream and was a blast to fly. It did bounce like a ping pong ball though if you didn't grease the landing.

I finally lost it as I was coming in for a landing at a strange field and whilst I was manuvering around a big tree at the end of a runway, this "gentleman" comes up and starts pulling on my sleeve saying "excuse me, thats a pretty plane". The result is my signature line. I've always said I was going to put it back together but now all of my planes are much bigger and I had just about forgotten it until I saw this thread.
