Nice review Chris! One complaint I keep reading about is the lack of center detents on the trim controls aft of the stick. Don't know why this is a sticking point with people. I can't for the life of me think of a single aircraft type I've ever flown that had any center detents on the trim wheels, can you?

Well, my nitpick with that is that the trim wheels are named that only out of convenience really. In a real aircraft, no, the trim wheels don't have detents, however in a real airplane you can't remap trim wheels to other functions - they are what they are. On a HOTAS for a PC game - you might very well want to make those trim wheels something like the X-Y axis for a radar cursor, or perhaps be the controls for tilting rotor nacelles on something like an Osprey, or maybe map them to the elevation and azimuth scan volumes for a radar. Without a central frame of reference for where the rotary is (is it rolled full forward? centered? full aft?) you don't have any idea where your sensor is initially pointed. In the case you present - purely keeping the rotaries as trimmers, then yes, you are correct that detents for the center position is a non-issue.
Hope that clarifies why I think they would be a worthwhile addition. It is worth noting the X52 rotaries have that center detent. Oh..I just thought of one other reason it is worthwhile. For some functions you may map the rotaries to "bands" where when the rotary is out of the center position it is giving repeated keypresses as programmed. For instance, rotating the rotary into the 60 to 100% band might be something like - continuously add flaps until I neutralize the rotary. Without being able to feel where center is, I can never guess where exactly the center is so those keypresses will still be continuing. I hope that makes sense (?)
Edit: Also one other thing. There are, in total, 5 rotaries: 3 on the base of the stick labeled "Trim 1", "Trim 2", and "Trim 3". Just because they are named "Trim" doesn't necessarily mean you have to assign them those functions, although it would be logical to map them to elevator, rudder, and aileron trims. The other two rotaries are on the split-throttle. They aren't specifically labeled "trimmers", but they too lack the centering detent.
Thanks for the question...it was a good one!
