I have discovered 2 issues so far with the CH-49. One of them, which is minor, is that even tho the helicopter doesn't have any weapons, when on the pilot seat on the top right you will see "Burst 180". The other problem is that regardless of what speed your flying at, if you touch the ground it will stick to the ground and doesn't take any damage. The earlier helicopters had the same problem, i don't know if this ever got fixed.
