I used the search function and couldn't find this anywhere, if it's been suggested before, feel free to lock/delete this thread.
So, a simple suggestion, make the wingtip smoke caused by induced drag to fade out faster and if possible, make it show up only at high g turns, not in a simple slow barrel roll.
Also, correct me if I'm wrong, but in game, the rockets fired from the typhoon have no convergence, I do believe that in some cases in WWII the rockets had convergence, not sure if all were like that, but if that's the case, would be a nice thing to add.
