I have now about 1 hours of flight on Magni Orion, 2 hours on Auto-gyro Calidus and about 5 in MTO Sport.
I was thinking about all the debate about the stick stiffness of the Magni. Is it only related to a heavy rotor that act as a fly wheel who want to keep it's rotational momentum?
My observation is that since the Auto-gyro Calidus and an MTO Sport shares exactly the same rotor system, the difference of stick stiffness between the Calidus and the MTO Sport cannot result from the rotor assembly. My guess is that the weight of the whole machine make the difference between the Calidus and the MTO Sport :
When you move the cyclic, you move the rotor in a direction, but you also push the rest of the gyro on the other way (action/reaction). If we look at a gyro as a pendulum, the more weight we have under the rotor, the more effort will be needed to push the rest of the apparatus from the rotor axis.
If I'm right, all enclosed tandem or side-by-side gyro should have a stick clearly harder to move in flight than a light single open machine.
Flying solo or with a passenger should also impact the stiffness of the rotor control. Since I'm not yet solo, this is an hypothesis that I cannot verify.
So can someone confirm/infirm that all enclosed or heavy machine are prone to stick stiffness? And if flying alone or tandem make any noticeable difference?
