I have to dissagree on the H9 P-51 PTS.
I have flown 5 high wing trainers and even another sport low wing. I got 16 flights on my P-51 and visibility is what got me in the end.
The airplane is predominately grey and is somewhat hard to see. At any distance it is almost impossible to quickly judge orientation.
I do not think the Hangar 9 P-51 PTS is a good trainer.
