At the suggestion of Bill McMullen I replaced the push button switch on my cyclic with a toggle switch. The reason for the change was to allow me to tell at a glance if the governor was on or off. Since the governor could be controlled from either cyclic I was impossible to tell without an annuciator if the governor was on or off. I bought the toggles from Infinity (the manufacturer of the grip) at OshKosh this summer.
Photo 1 shows one grip with the toggle and the other with the original red push button.
Somehow I got shorted on the bushings for the ground wheels. Instead of bothering Bobby and Sean I just made some up out of Nylon. Photo 2 shows me cutting off the finished product.
