TBH, not really from what I have played so far..... Not 100% sure but I don't think planes have a best turning speed either.
As I was saying to haz last night as well, the repair system is quite different for vehicles now.
You get damaged, you just have to hold x to repair your tank now, when you are doing this, you can't do anything though. Sames goes for planes and they will get their full mobility back after this.
Once the tank is disabled, it has to be repaired in order to be able to move again, no recovering mobility after a few seconds like bf 4.
One thing for sure is tank players can definitely not be any where as aggressive as what we could be in bf 3 and 4, best to keep your distance and let the infy push the flags.
It is a fun game though.
