Having heck of a time with cg at manufacturers setting. I have built a platform out over the engine and mounted two of the heaviest batteries I have right over the engine and this sucker is still tail heavy, to the extent I am afraid to fly it. If this plane was designed to fly with a 120 nitro engine I don't see how one would ever balance it, short of a brick in the nose. Would like some info on cg for this plane, from experience.

Just noticed your WillHobby YAK info. Agree the manual and hardware are useless and the fiberglass parts of very brittle. The landing gear is far too light weight for the plan.I heavily reinforced the firewall and installed a Saito 180. In order to get CG at the location specified on the plans, it took 2.3 lbs of dead weight. How did you fair with the CG problem? It seems to me that CG over the wing tube should work but am afraid to try.
Plane looks nice and may be in a new category - "CTFTK" Closer To Flying Than a Kit.
