I'm having a similar problem with engine starts, on 2 occasions. I have a Logitech throttle, and a GF-TQ6 throttle unit. Having started up X-plane and the Saab, I assigned the Condition levers to 2 axes of the TQ6. I find that I have to do this each time I select the Saab in X plane, it doesn't keep the assignment. I carefully ran through all the prestart checks. When I select left engine start, (doing manual start) there is the sound of electrical equipment 'dying', which I think is normal, then a whine, which I think is also normal. The left engine ignition light comes on. The temp rises to 32C (same as wim1976) ...and then nothing else happens. The whine of compressed air (I think) remains, but after many minutes nothing else happened. Tem still at 32C. I tried a rt engine start, but same problem. I tried Autostart - but it 'got stuck' during the initial start up phase too. any thoughts? cheers
