I recentl downloade the B747-200 in the NorthWest paint scheme it looked great and had desent flight dynamics but had 1 little problem the contact points were not quite right and the right main gear was burried in the tarmac and then when you started the engines it would bounce like crazzy on that side. I found there was a error in the contact points and corrected it and now it behaves like it is suposed to. It also wanted to slide around corners and not turn.
Other than that it was ok and was not hard to correct the problem it was a key stroke error one point was -16 and it should have been 16 no minus sign which mens a negative value. With the main whells you have one that has a negative value and one that is positve. a simple mistake was made
