(I posted the following somewhere else. It is kind of confusing trying to find a place where to post your question. Just tell me where to post if this is the wrong spot)
RC4 still has the same bugs as the release before:
1. The joystick xml file for my particular brand does not work at all, the view is rotating like crazy and does not respond to any input.
2. Some aircrafts only respond either sluggishly or sometimes not at all to input and thrust and other controls are constantly changing by themselves.
3. Terrasync does not work at all. I can't refresh scenery and get new airports loaded.
4. The helicopters don't work. The controls are so sensitive, just by touching the joystick without even moving it the aircraft crashes instantly.
I uninstalled and reinstalled FG many times, using both methods for the "force 32-bit install on 64 bit machines" option.
Maybe someone can report these bugs. The only link to a bug report takes me to my gmail login; I guess to access or download some kind of program (that I have to learn) and I don't have the patience to do so now. I am reverting back to 2.6.0.
