Dear Amram;

Thanks for your reply, but I only loose one F3A model, my old one still alive.
I fill the gap with 3mm hard balsa wood, as I remember, and I push the stab together a little to drill the hole for the fixing screws, but fuselage was not pressed. After that the stabs looks very good fit and do not have any play in any way, my old models with fiberglass fuselage are not as rigid. The stab tube is not damaged, and the sleeve and fixing screws for the missing stab are still on the stab tube together the right stab. It is very small quantity of glue in the stab sleeve, only in the stab root and one drop of glue in the fixing screw place, in my opinion is not enough.

Best Regards. Alfonso.
