WOP Hammerhead possible?

Hi,I just downloaded the latest ** P51, and it's outstanding! Only one thing I'd like to know:When trying to do hammerheads I always end up in some uncontrollable stall situation as soon as the nose points downwards. What am I doing wrong?Just to compare I took the old RA Spit for a ride, and the hammerheads went like a dream, even if I have to yaw right in the Spit, which I'm not that used to. Actually, loops and rolls was more fun in the Spit too. If the ** realism takes away the fun of flying the sim, I don't know how cool it is ...I don't mind practising tho, so if anyone could provide me with some info, I'd be most pleased :-).Eagle
