Thanks swift bill. This plane certainly has it weakness' and I am trying to eliminate or at least reduce the chances of problematic occurences.

On the same theme I have spent quite a bit of time reinforcing the landing gear mounts. I have added 1/4" balsa stock to support and craddle the mounts in three of the four ribs, this increases the glue area making it a much stronger connection. Additionally, I installed shear webbing in that area making a very strong box frame. (Note: the grainon the shear webbingwas installed vertically for maximum strength) The landing gear mount block at this time is only sitting in its newmount, it is not yet epoxied in place. The reason I did not place the 1/4" square balsa on the second rib is because there will be a torque block that will be epoxied to the underside of the mount in that area. I believe all of these steps will correct / strengthen an overlookedarea that was prone for damage.
