If you dont want to remove the tail, then cyano it back together again, and use closed loop wire to form 4 braces to hold it together.

I used it for my capiche - my tailplane broke because I used too soft wood and it failed in flight too.

Make up 6 brackets from strip aluminium (B&Q sell the stuff), angled at around 30 degrees with a hole each end. Bolt 2 either side of the tailplane (both sides) about 2/3 rds out from the center, bolt 2 either side of the fin again about 2/3 rds from the bottom of the fin. Use a flat piece of aluminium strip and secure it to bottom of fuse under the tailplane, by screwing it into a piece of 1/8 ply cyanoed to the bottom. Now secure one end of the closed loop to each bracket and use closed loop adjustable ends (with a clevis) at the other end. This way you can tighten up each wire in turn until the whole assembly is stiff enough. Its very light and very strong, and works.

Phew, harder to describe than do. If you want a pic let me know and I can sort something out in a few days if you like.

Otherwise if you want to get rid of the airframe I'll take it off your hands
