Sorry I have not been able to play the game or reply to these lately due to work. So basically this issue I reported might be able to be reproduced but only using certain choppers. The two where the little bird and passenger one from alpha. I have not checked if it can be done in Beta at all. The best I can say is to do a mission based online server. The server I found this issue was on Dog Company's Server. I do not know if this will help at all, but I notice many problems with this server. Hope this helps and sorry for such a late report, my job has been tough lately.
