Default Sky Master F-15

I have an older F15 I have not flown it in some time. I flew it yesterday and it would drop its nose in a turn a lot .It's the tail Alon version. Cg is on the front spar. It was a hand full any ideas? Thanks Frank

Move the cg back about 1/4" to start with. Do the 45 degree inverted cg check. The YA F15 cg was about 7.5" behing the leading g edge of wing.

I flew one of those with the recommended c of g and it did the same. Was diabolical. Move the c of g back for sure. We rebalanced it by using the yellow and avonds models as a guide and problems were solved.
