Can I just say as a clarification that I admire you sim builders enormously and sim aircraft like this have given me a lot of pleasure for many years. I wasn't criticising anyone or telling you off, just pointing something out and seeing if there were any possible resolutions. It would seem that as another poster stated, if you start with a default aircraft first, like the Baron, and then transfer to the saab, the props don't windmill, so that's fine. This is a great aircraft and I did my first proper flight in it yesterday from Aberdeen to Sumburgh and thoroughly enjoyed it. Thanks for the video too Cameron. I was using my dad's RW Saab manuals and it would seem that in the sim, the COND levers have to be moved to START before using the engine selector, and in my dad's manuals i'm pretty sure it's the other way around. It's starting fine now. Cheers for the help, John
