911, to elaborate on the landing gears a little more, if you upgrade to "fixed" gears on wing, try to bend them forward a little. You should see part of them from above the plane looking down. This should help nose over.

When you get tired you straightening them all the time, try what I said above!

I used one or those new type fiberglass dural landing gears. Put on bright red 60 size wheel pants, not scale but snazzy! .
