Hi, there we go,well, if X-Plane has a total energy vario, it is compensated - that's one of the two real-life compensation techniques. And it's the one in the FU3 challenge, too... :)Blue Skies, Steffen

This is quite interesting and it would be an interesting project as well... I might(read MIGHT) give it a go... probably without a map to start with(just a list of locations to start from)hmm, is there any way to load fu3 and start a challenge immediately? because that would be easier. what about allowing miracle up + miracle down. the mirical up & down things i would like because otherwise if your just learning then every time you crash you have to restart the challenge.
