I really love the P-51H. I grew up around one of the only two flyable H's, so it is dear to my heart. This Aircraft Factory Mustang is a really nice representation of the "H". But I have been a little disappointed with the product. It has some minor issues which I've noticed. The sounds are very nicely done, but on external views, when viewing from the front right side, at idle the engine mid idle comes through.
The sound issue is from an error in the sound.cfg file. Under the section [COMBUSTION.1.09] the filename should say filename = xwop_p51_rpm1_front
instead of filename = xwop_p51_rpm4. I made this change, and everything sounds fine now.
I have also noticed that the looping sound at high rpm does not loop smoothly. I can tell when the sound starts over again. I haven't had time to fix this looping sound yet.
I noticed the tail wheel seems to always be off the ground. That was an easy fix, just edit the aircraft.cfg, look for the section called "[contact_points]", then go to the first contact point line and change it from this:
point.0 = 1.000, -17.300, 0.000, -4.000
, 3000.000, 0.000, 0.550,
point.0 = 1.000, -17.300, 0.000, -3.870
, 3000.000, 0.000, 0.550,
This will put the tail wheel back on the ground as it should.
I also noticed on the top leading edge of the rudder, there seems to be a slight deformation. It appears as a couple of triangles (inside the circle on this pic)
I can't fix this issue myself since it is part of the model.
I know that this is an Aircraft Factory plane, and won't have as much detail in the moving parts and aircraft systems, but I am very disappointed with the animation for the center landing gear doors. They act like they are directly attached to the hydraulic release lever on the floor of the cockpit. As soon as you pull the lever, they are completely down, and when you reset the lever, the doors immediately close. They don't have the realistic drop that I've seen with so many other mustang simulations, and these doors don't seem to require hydraulic pressure to close them back. Very disappointing.
The other thing that I don't think is correct is the propeller. It doesn't change pitch with the controls. The engine will react as if the pitch is changing, but the pitch doesn't change when viewing it. I hope this will be fixed.
Overall I am somewhat satisfied with this plane, but I feel it could have been better. There are other little things that I won't mention because they don't bother me enough, but overall I feel that too many bugs got by the testers for me to be totally happy with this one.
