This is to hopefully trigger some interesting
discussion, as this group has been lately
infested with questions and answers like
" are Futaba transmitters better than JR ?"
I remember much more in-depth discussions
here. I do not mean to offend anybody, however.
The question is what would be wrong with replacing
the flybar with all the mechanical parts that go
with it (seesaw, mixing levers, etc.) with two
gyroscopes polarized 90 deg. Well, perhaps stronger
and faster (by how much ?) servos would be needed.
Mixing the control inputs can be done electronically
much easier than having it done mechanically (as with
the flybar arrangement). In the age of solid state
electronics is the flybar a dinosaur ?
I just have on my desk an article from
August, 1948 issue of Aeronautical Engineering Review
introducing the invention of the flybar (Stanley Hiller).
There is a picture of a fellow hovering his little
open***pit heli about 1 ft. over the ground
totally hands-off !
