I use a T16000M with twist for rudder. Carenado is fine.
As to SWS, you can use twist rudder, but then the skill factor I spoke about above comes very much into play. I would also wait till they resolve their FM issues, which have been acknowledged by them and are a WIP. They can take a couple of goes to get it right for lower level setups too, so I wouldn’t be in a rush.
Yes. Less stress = more fun. KISS.
Note: Some users reported frame rate issues with the Carenado PC-12 Avidyne FMC on long flights. I personally never had issues with it, and it was supposed to be fixed in the last update, but if you do you can just switch it off and use the other FMC. It’s also PMS50 compatible, tablet configurable.
