Well I saved myself a few bucks... I realised that the plane I am scavenging parts from to build this plane already has a CF wingtube. Its a perfect fit.... Now I just have to replace the one in my Eagle.....

Oh and by the way,,, Steve, I did go ahead and reinforce the elevator servo that is mounted to the floor with a cross brace, it did stiffen things up without really adding any weight or taking up any of the "limited"[8D] space in the fuselage of the Genesis....
