And the reversing system of slowly lowering the stick to get it to back up is so terrible I cannot get my tank to back up without several tries.
One of the things I dislike about the IBU2 is it seems like you have to wait a couple of seconds before each "command". So if you try to fire the gun twice rapidly, for example, the second time nothing happens. You have to wait a bit and then fire the gun. I find other motions have the same "lag", too. Maybe that is what you are talking about with the backup.
I love the inertia. I like how the tank slowly comes to a stop when you take your foot off the gas but don't press the brakes.
