Hello Bill. Thank you very much.
@bnsgeyer @heri We didn’t update because of vibration problems with our helicopter. Because our vibrations are so great, they trigger some extreme situations. In this extreme case, the 4.0.7 version performed a little better than 4.1.2. So we haven’t updated yet.
But Bill and Leonardthall took care of it for us now. We plan to update it when the new version comes out.
@heri You can read our previous posts about our vibration problems.
