How are you compensating for the weight of the top wing? If you want the perfect CG, use a Vanessa Rig with the plane fully assembled. I gave up trying to point balance planes, especially when they tend to slip off prior to getting the weight placed for balance. Before I lost mine to the throttle arm coming loose on the carb, mine was balanced to the point no trim was needed and it flew great. l may get around to rebuilding it some day, both wings survived, only the points where the wings attach to each other snapped off, and the fuse is intact from cockpit back, most of the front structure is there, but cracked. The wood was pretty much fuel soaked when I got it, so most will have to be replaced anyway. It was a fun plane the couple times I flew it.
