Hello. I have just recently started having issues with my 701 governor. It has stopped engaging although the back plate sensor is still working and it is recording engine run time. It has just now started occasionally working but at much higher than the set rpm. Basically it is behaving erratically. The sensor has 16 hours on it. Can this occur with a failing sensor?

I'm not sure if it's just my imagination or if the settings occasionally change by themselves (I would usually be the last person to suggest such a concept).

I have two GY701's on gassers, the controllers have been rock solid, but I have had a few of the original (non-backplate) sensors act up over the years.

Since it has worked for a while, all your curves are good? Same throttle servo? Always worth resetting low and hi limit and checking curves, V curve min for idle ups must be higher than gov start %.

I'm using the flight mode switch in idle up 1&2.

Issue found.

As with most things in this hobby, human error.

I had recently incorrectly re-set the idle and high throttle points causing various issues.
