Hi Stuart, Congratulations! It is indeed the whitespace. I've been dealing with that too. Just change it to an underscore, and it will be fine.

I'd suggest that the control input should be reversed, because that is the biggest problem a fixed wing pilot encounters when transiting to this kind of flying. Pushing the stick to gain height is very unusual to us. A very pleasant aircraft! Greetings Detlef - Take Surveys. Earn Cash.

Stuart Buchanan schrieb: Hi All, On Wednesday evening I flew solo in my microlight for the first time. In the tradition of FG RL flying posts, here's a quick description. Hi Stuart, first congratulations for your first solo flight. This is a very interesting report, I liked to read it :-) I've also been working on a FG model of my microlight, a Mainair Flash 2 Alpha flexwing. It's available for download from http://www.nanjika.co.uk/flightgear/flash2a.tar.gz Thank you very much for this nice model which closes the gap we have (had) for micro-/ultralight a/c in FlightGear. It is a joy for scenery exploration, slow and stable to fly. The model is fairly accurate - though missing an EGT gauge at the moment.
