I built a BUHOR, it had horrible flutter in the ailerons. I crashed it and folded it in two. Then I built the foam trainer. Now, I fly anything and help out the new guys. All this in 3 years. Oh yeah, my simulator has saved me thousands. I still use it too, it's fun to play with when it cold, or dark, or windy, or rainy, or too frigging hot to stand out side in the middle of a field in the hot, muggy St. Louis summer.
