Ours is not quite that complicated or expensive... We have an electric release made from a old GM door lock actuator ($2@PnP). The cable backup manually pulls the door lock actuator.
I will always advise that parachutes need to be actuated without removing hands from the wheel.
During the months of lakester tweaking, Don & I kicked around the idea of a steering wheel mounted, button chute deployment system; priority was "nice to have".
however...
Immediately after our last pass chute deployment at WOS, Stainless gave TFA the advice he stated above and we were in a VERY receptive mood; The priority is now = "have to have"
(HTH did SS get down to the 6? so quickly???)
Thanks to azgearhead for starting this topic, TFA is "all ears"!
