You can half bank the turn, just lead with the heading bug slowly, yeah it sucks but it's better than doing a snap roll at 270.
As for MX issues, I was at Colgan and part of the Initial Cadre that brought those beasts on line. Even the 402's had their share of MX issues, mostly pull circuit breaker and reset. A lot of the problems arose from the 402's having new software and slightly different logic. They are a great airplane for the mission but you have to baby them. I fly the older 400 and 401 models along with 1 new Next Gen in Japan and we don't have near as many problems as Horizon or Colgan. The difference with the Japanese is, they don't cinch on MX. They actually perform preventative MX, and our dispatch reliability is probably in the 90's. A good example of this, If a part requires changing after 5000 hours, they change it in 3000. I've never carried more than one MEL, and can count on 1 hand how many times I've had an MEL. I have had twice where the APU was MEL'd, but at every station before the props stopped spinning, they were hooking up external power and air. The next day the APU was fixed.
When you leave the Saab, you'll miss "FLYING" the Saab but you'll enjoy not having to get creative with the load sheet and actually be able to take bags, gas, and butts. Also, the AP is sloppy on the Q, just because the darn thing is so long and squirly, the Saab AP was great, rock solid, auto trim on the rudder. You could be inverted in a category 5 hurricane upside down, throw on the AP, the ol' girl would right herself and keep on truckin'. The Q, if you hit a light speed bumb, "George" will thumb his nose and refuse to fly.
