Hey all you past/present owners and flyers, need some information and advice. I also asked Mike Mac (M&M) the same question. I know the instructions say to use CA hinges for the elevators and the rudder but have any of you used Robart hinges instead. I know the woods thickness is questionable but have any of you tried it with success? I am building my Ultimate with a new covering job and I am about to hinge the surfaces. My Ultimate is covered in white, red, black, and green (the Krispy Kreme logo colors). No, the Ultimate does not look like a donut but it does look good. I also installed K&S Cannisters on the DA150, can not wait to hear the sound. Thanks to all who respond. Chic White
