X-Plane 10.45 Beta 1 is out – here are the release notes. This is a small update in terms of code change; the new feature is updated global airports and nav data, as well as a bunch of bug fixes; the beta period should be relatively short.
To get the new beta, run the X-Plane installer, update your copy of X-Plane and make sure “get new betas” is checked.
Prop torque is fixed in X-Plane 10.45 beta 1; the calculation was incorrect (causing too much torque from props) in previous versions of X-Plane.
In order to get the new correct physics, you must resave your aircraft in Plane-Maker 10.45 beta 1.
We have heard of authors doing a number of things to lower the effects of prop torque in old versions of X-Plane, including having plugins apply a counter-torque and tweaking the physics parameters of the aircraft itself. Because we cannot know if an aircraft has such work-arounds applied, the prop torque fix is applied only to aircraft resaved in 10.45 beta 1 or newer. This way the fix takes affect when an aircraft author can remove work-arounds.
