Ah, thanks for tracking that down, Stuart, and DF for fixing it!
Dacer, in answer to your PM'd questions, the FG Typhoon does not utilise FlightGear's full radio navigation potential as the real aircraft only uses TACAN and GPS for navigation and does not support civilian systems. I've never been able to get VORTAC stations to work in FG personally, on any aircraft, but I might just be doing it wrong. As far as COM frequencies are concerned, the aircraft has a similar system to the real one, in the form of preset channels and doesn't use the standby/active frequency system that civilian aircraft use. You can enter two manual frequencies, M1 and M2, but it looks like I forgot to finish the dialog for entering those - my bad, sorry. I'll get that done this weekend.
As far as stalling at 240kts is concerned, that's never happened to me - you should be able to maintain level flight with high alpha (AOA) at anything down to 150kts. Can you give any more information about the situation in which this happened?
