Need some help. I've got an Ikon N'West Monocoupe with an OS Gemini 1.60 for power but I need to know the correct location for the CG. Anybody out there that can help me?

Thanks in advance

Jim, I can't locate my plans, but my Coupe balances on the spar.

3 5/8 inches from the leading edge, lots of flights at that setting
this is the 90a version

Thanks very much for the info. Mine is the 90A version as well. I'll try it there.

I also am building a Ikonwst 96', using a g38 for power. What is a good finished weight? Would my cg be in the ball park as yours?
Thanks, Wildhair

Mine is powered by a G38. Don't know the weight, but it's finished in 21st Century Fabric. Dual elavator, and a rudder servo are mounted aft. Battery is in the cabin area, near the CG. No additional ballast was needed.

Mine was totally unflyable at that CG location. Incredibly tail heavy. I had to do an emergency (crash) landing in a pond to keep from completely losing the aircraft. Damage was minimal thanks to a lot of luck and a fortuitously placed clump of reeds. I have to believe that the 3 5/8" CG location is 1 - 1.5 inches too far aft. I have not attempted to fly mine again but will be adding a whole lotta lead to the nose before I do.
