Landing a Giles 202 !

I agree with Fred. Increase your speed on final and make a "mains only" landing. Don't try to "3-point" it. Dr.1 Driver "There's a Hun in the sun!"

Reduce your elevator throw when landing and or move your CG a bit. Tail heavy planes tend to fall out of the sky when trying to 3 point them unless you are extremely careful and do a lot of high altitude slow flight work. Then it just becomes an issue of luck.

YMMV

Sounds like you are using to much elevator in your flair. You can't get the nose too high on landing. If you do add a couple of clicks of throttle and let is settle in. When done right it will stop the wing from snapping over.
