For comparison I did few tests today in 1.5.3.52018 and 2.0.2.5226. Those test were made with the same settings and of course with no wind. But this time it behaved how it should in all four attempts.:huh: M2000C Take Off No Wind - 1.5.352018.trk M2000C Take Off No Wind - 2.0.2 Groom Lake - no rudder input.trk M2000C Take Off No Wind - 2.0.2 Nellis - test1 - no rudder input.trk M2000C Take Off No Wind - 2.0.2 Nellis - test2 - with rudder input before take off.trk
