In my previous post I mentioned that re-saving your aircraft in Plane-Maker from X-Plane 10.45 would opt you in to the new fixed torque model.
I've talked about this before, but it might bear repeating now:
Please do not ship an aircraft saved with a beta version of Plane-Maker. Instead wait for X-plane to go final or use the previous non-beta version of X-Plane.
The problem is that file formats change during beta and if they do we do not provide compatibility; the file format is only "for real" when beta is over.
So if you need the torque bug fix, plan to ship your aircraft in a week or two when 10.45 beta is over. If you need to ship now, use Plane-Maker 10.42. Test against the beta, but don't save using it.
