yes, there is a problem just when the wheels touch the runway. We hope it will be fixed in a next release.
What you have to do to stop the aircraft :
- at the touch, cut the power, switch the “reverses” button (you have to define a “reverses” button on your joystick in the Comands window) and push the throttle to the max. Obviously you have to use the brakes in the same time and to keep (if possible ) the center line of the runway.
