Anybody successful in performing a loop (… looping?)? While I could perform stall spins and barrel rolls quite good I fail to perform a looping as the Texan reaches the upper position and doesn’t transition into the inverted flight phase but simply plummets out of the sky. 
Edit: just found out that the problem seems to be using too much elevator. If I use 50% max then I can do the loop. The behavior when using full elevator (even during “normal” flight) still does not seem correct.
