1. Assuming you're talking about the gear handle on the inside? I believe that's all controlled by the cockpit scripts, but I'll take a look.

3. I've experienced this before. Some settings were not cleared on respawn properly, but I made some changes this morning that (from my quick testing) resolved it. If it's still happening with the latest v1.1 version, let me know.
4. I was able to launch the Meteor around 50-60 miles from a target at 20k feet. I've never had success with a 120 that far... are you not able to get that kind of range?
