After hours of messing with this game to figure out a fix or workaround for this bouncing helicopter glitch.
Here is the workaround, In the mission hanger click on management, fuel and payload, finally click on manage fuel either fill or remove until you have about 95% fuel then back out of the mission. It should be fixed until you get to a fuel level that glitches out. (Full or Empty)
Also note the Robison R66 is glitched it always ask you to set a parking brake at the end of a mission therefor there is no way to end the mission.
