No I didn't hear straight away. One guy in my session heard the next day over the phone. I recieved a letter in the post today confirming my acceptance.
The Q400 sim has only just come on line so it would make sense they use this for the sim sessions. I would say it would be slightly easier than the 743 as you are not chasing power settings for 4 engines and as the 743 is configured at 180000kg is is probably significantly harder to manouvre than the Q400. If you have been sent spec's for the Q400 then there wont be any suprises.
Best of luck
