Way too slow at altitude, climbs too bad (about 2.3 meters per second too bad to be exact). And the fact that the GM1 and MW50 don't seem to modelled at all. Specially not the Gm1. The only thing that is modelled with the GM1 and MW50 in the TA152 is the weight...
But then again, I've posted proof several times so I really don't know why I care anymore, think I'll just drop it here and see what else will go wrong...
