Okay, the exterior and interior sound matches what I hear. I'm guessing the "real engine" sound for exterior was recorded with aircraft at idle on the ground. Thanks for the feedback.
Exterior view engine sounds are un-realistic and sound like an old windmill. Interior engines sound are great. Anything I can do to improve the exterior engine sounds?
Using X-P 10.30 Beta 4 and can't select/change radio frequencies for any of the radios. Mouse will select on/off know and turn it but not frequency. Suggestions appreciated.
