I don't have this plane, but have been flying a H9 cap for quite a while with a saito 180. I used to have a snapping problem, but made a few changes, and now it flys a lot better. It will still snap, but is a lot better to land. I read an article in the AMA magazine I think, back when they were doing the series on the project extra. The article talked of a dead range on elevator travel that results in bad snapping tendencies. I think it was when your travel wis between 27 and 37 degrees. So I checked mine, and I was right at the low end of the range on low rates, and pretty close to the high end on high rates. I changed my lowe rates to 25 deg and my highs to 45 deg, and the snapping tendencies went a way. It will still snap, but now it seems a lot more stable. On landing I basically line up and it settles in. It is suprising how slow it will come in now. This is something you may want to check into, it worked for me.
