Is the helicopter 'jigging' around on the mat a known bug?
Yes , it is a known bug. For some players it occurs , but not for others. It was reported on a different thread not too long ago. I'll explain to you ,as I did for him.
Although there is no known fix ,after a while a playing ,the helo jumping and shaking will eventually stop. After it stops , DO NOT readjust any settings. For some reason this will reactivate the bug ,and you will have to play another 30 minutes to an hour for the shaking to stop again. (It doesn't matter what settings are set to - just don't change them after jumping subsides)
