@hama was having trouble with the arrow's ground handling after the most recent update, too, but I fixed that problem with a change in my technique. Prior to the update, I was setting the elevator trim to be slightly nose-up for takeoff. That seemed to avoid the worst issues with abrupt swerving during the takeoff roll.
The new update includes Asobo's new ground friction parameters, so the front wheel will have more friction now than it did before. If I set the elevator trim slightly nose-up like I did before, the nose wheel will lift off the runway too early, and the airplane swerves into the wind. But if I keep the trim neutral and apply some light forward pressure on the yoke during the takeoff roll until I reach rotation speed, the airplane's ground handling is excellent.
