First of all, great job! I love this mod, the models are great, and the VTOL animations look great! I'm having an issue with your mod. I take the KF-35, after a while...game crashes everytime. I don't know if its related to mk2_thunderbolt, or KFAN engine, but the outputlog gives some errors related to them, and with FAR and JSI related. I have lots of other mods installed, including FAR, JSI Rasterpropmonitor, Throtle Control Avionics, and more. Can your help me with this issue? May I post the outputlog??? Kind regards!
