I believe the lag you're experiencing on rotation is due to jester turning on the radar as soon as wheels are up. On heavy MP servers I have to take off with the jester wheel open and the radar standby option highlighted so I can quickly tell him to disable it as soon as I feel the game freezes happening. It's saved my life a few times but takeoffs still remain pretty risky! The other alternative is to bind the radar standby jester action to your hotas. If you tell him to go standby on the ground, he'll still turn it on at rotation since it was already in standby.
Try taking a look at the new radar performance options in the specials menu. They might help with the rotation lag.
