Up to now there is no example of a helicopter with a bell-hiller rotor head for flightgear. The UH1 has the bell rotor head with stabilizer bar, but as far I know the cvs version of the uh1 is broken since some days. I have no idea, if or when helijah will commit my patch. Maybe it's easier if you just provide a (maybe very simple but right size) 3d Model of your helicopter. Then I can make a FDM similar to my rc-helicopters. At the end we only need to adjust it to make it fly as your helicopter does. > Thanks again, > Thomas Best regards, Maik
