Hi
There is a hard balsa stab brace that buts against the stab L.E. (C drawing) further there is a sub bulkhead that adds extra strength for the front wind dowels ..lets see a 3/16" plywood brace to accomodate the wing bolts near the wing trailing edge -and there is a 1/4 balsa platform that was intended for the 'pipe floor,'as this aircraft was designed for a rear exhaust tuned pipe,which I'M not incorporating the fuselage pipe platform helps with added rigidity extending from the 'firewall rear,'to aprox the rear of the canopy.

The stab will be aligned and epoxied AFTER I drill,tap and bolt on the wing and yes I will add an epoxy fillet around the horiontal stab.

I built and flew my FIRST Tigertail and it was structurally sound around the stab fuselage joint even after an un expected vertical landing I can grin now..
