Roger that. I moved the CG forward to 15 cm, not quite as far as the full 93% scale of my plane which is 14.7 cms, as you pointed out earlier. Glad I made a reference mark at 16 cms as soon as the build was done. Nose is a bit flatter now! Hard to guess exactly where it is/was.Take the CG back towards the original position that you were using and do the balance test as set out above in post #29.
I noticed a couple of other things I need to address. One of the FT linkage stoppers is binding up and flexing the control rod. I love the idea of linkage stoppers but half the time, they bind up on me and don't float with the control rod angle. Not sure if there's some trick I've missed. The identical stopper on the other side installed the same way works fine. One of the elevons isn't rising as high as the other. Gotta check that out. Probably why it was pulling left.
When I flew today, it felt like it was flying better in terms of not being so unpredictable and erratic so I think sliding things back a bit should help. I don't think it will take a lot. Learning a lot about CG. It's funny how someone can describe something to you but until you see it for the first time, their advice doesn't register and you have to go back and read it with knowledge of your new experience. I'm happiest when I'm learning so even when the plane doesn't fly, I still enjoy scratching my head.
