Surging governor

[TomCarey]

Good evening all,

After many faultless flights both of my 700n dfc helis have gov issues, the magnets are registering
on both helis, how ever in fligt they are jumping through rpm quite drastically. Im using the inbuilt
govs on the 7300bx.. anyone have any ideas on what to look for?

If it's both the helis doing it then I'd say it's transmitter settings or values being read. I'd recalibrate the tx throttle to the FBL maybe.

If nothing has been changed what could cause the sudden surging?

Logic suggests "nothing"..!

ie something must have changed.

Fuel and environment might be common to both helis.
