Very interesting topic and great efforts already, thank you very much!
I wonder if you know AeroflyFS which is so perfect on simulating physics. It is already fun watching the Cessna during taxi from external, seeing how it behaves when rolling on different surfaces. And take-off runs and landings are amazing as it is very important to control your aircraft right, for example not to slip in the moment of touchdown, otherwise the aircraft can get hard to control or you even risk to off the runway or to roll over.
Will we be able to see this also with the new possibilites through lua and FSUIPC? Does the dynamicfriction.lua loose effect on slipping touchdowns because it is thought for slower speeds?
