I have a Keil Kraft Elmira which has been in my many lofts over the last 50+ years! I have started the build and I have decided that I would like to reduce the dihedral and add ailerons and (over wing) air brakes. If anyone could pass on any knowledge and wisdom to help me with this I would be so grateful. Remember though, I've done absolutely no model aircraft building or flying for over 50 years, I mean I don't even understand how the the wing joining set up on the Elmira works! I have read Dave Hughes' build and flight test report and I don't quite understand the modification he recommends for the "rather soft silver steel" which he had to replace with piano wire. I seem to have very stiff wire in my kit. Did KK upgrade it? Hoping for help, Roy Barber
