Thanks for your feedback - however, I respectfully disagree.
The thing here is (and you can see plenty of discussion above) - the flight model has been designed to fly like a CH47 with the SAS System on. The current flight model does behave as such within the limitations of simulation: Pedals on the CH47 provide a yaw-only movement as the flight computers will provide the necessary input to keep the helicopter in a stable position, the cyclic will provide pitch and roll movements only as the computer will respond to the other undesired intertial reactions and account for them (and has been validated by at least two CH47 Pilots) - that being said, DinoPete has a very interesting opinion on pilot feel and MSFS FMs, which is worth a read: Cera Sim Mi17 - #257 by DinoPete11
Ultimately we must cater to the largest audience possible - and the general opinion talks for itself. It is unfeasible to change a flight model when satisfaction is >90%
I’ve explained everything in detail on my forum post here: On the topic of CH47D, Tandem Flight Models and SU15...
Edit: The following document in theory of operations of the CH47 does corroborate that the flight model is correct in the 3 main axes: https://www.chinook-helicopter.com/Publications/Theory_Of_Operation/CH-47_Theory_of_Operations.pdf
As you can see pedal provides yaw only, cyclic provides roll/pitch only. Combination of yaw+roll is required to perform coordinated turns.
