I discovered the guilty that make it crash/freeze.
RealityXP plugins
I have the GNS 530/430 and the GTN 750/650, when i remove them the aircraft loads well, when i open the DC3 after the C172 with the rxp plugins installed, the aircraft load and a micro second after it flips around/upsidedown (like roll +120º to the right) and crash freeze the simulator.
So, something is not going well between LES DC3 and RXP I have the lastest GNS and GTN plugins and xp12.06r3.
Other aircraft with GTN works well!
Thank You!
