One was on the carb heat and broke before my first 25 hours were flown off. The wire failed at the inlet to the grip. I have a second unit on my cabin heat control and it has 420 hours on it now. I'm not sure why one broke the wire and the second one didn't but given the number of failures I have heard of in the past(not just on Lancairs), I wouldn't use these units for critical engine controls without understanding why some fail the wire. My guess is that the wire is pinched tightly right at the inlet to the grip and a natural frequency of the installation is being excited leading to a rapid fatigue failure. Change the location or the stiffness of the installation and you may never see a problem.
