Hi John,
Do you mean that there is yet a newer version with more light over mp?
I have been flying the newer 747 for a while now and one thing is not quite right i think. You said the ground handling is better. That is true. I guess you did that with more grip on the tires. But together with that the touchdown has become less good. At touchdown there is still a lot of lift, so the grip of the tires should not be very effective. But when i touchdown now, it feels like there is immediately full grip of the tires, making a slight traversal landing ending in almost tipping over.
Kind regards, Vincent
