[simpits-tech] CH stick

[Brian West.]

Justin,   Had a thought last night after reading your message about loading
up the linkage. You really need to feel that you are moving flying surfaces
around with a bit of a stick through treacle feel.
 I thought of using a  pair of unpowered  D.C. motors belt driven from the
shafts with a ratio of about 3 to 1 to provide resistance.
The next step would be to power them via a relay from the switching current
of the C.H. feedback motors.
Do you reckon this would be feasible?, it would certainly be easier than my
original idea using small pneumatics.

Regards,    Brian West.
