I haven´t read the other posts, so i don´t know if i am repeating them, but here are some considerations when you use a T-tail. First of all, the vortex on the top of the fuselage disturb the elevator function of a T-tail. This has been helped by f. ex. on the MD80/90, strakes. The other fact to take into account with a T-tail, is that at high pitch, the elevator tabs will have problems. This means stall problems, and problems getting out of stalls. That´s why some T-tail plane have extensive stall avoidment systems.....
