I have the same issue with every Carenado aircraft I got (all up to date). Don't know what does cause this ugly squeaking sound. I especially got that issue when switching outside views. Sometimes there is a freeze in that moment (5 seconds in time or so). I have some other aircrafts (CRJ 200, Saab 340, Mu-2) - no problem with them. Gizmo is up to date, cause I bought them at X-Aviation.
Maybe someone of you can post the issue here: http://forums.x-plane.org/?showforum=106
Posting a thread there doesn't work for me. Daniel Klaue is very nice and could help if he only know about it.
my system (eventually it is hardware-related):
Intel i7 3770
16 GB RAM (1600MHz)
Radeon HD 7870 (Catalyst 13.9)
Windows 7 Pro 64Bit
X-Plane 10.25 64Bit
