This update adds the following...
A bit of a rework for the flight model as I introduced a bug a while ago that made the roll rate of all helicopters (apart from the Comanche) far too fast.
I have now adjusted the roll rates of all helicopters to be much closer to their real world stats and this may mean you will need to adjust your controls accordingly if you found the helicopters a little "twitchy" before.
Feedback very welcome on this ːsteamhappyː
Optimised some other physics systems related to water buoyancy.
