Vertical Freedom: I've been involved with 'jetties' (A, B and L) for over 40 years and all of them had two clicks, all of them. The next time you sit in your 'JetBox', close the doors and ensure the cockpit is quiet. Put the twist-grip to 'shut-off' and then slowly roll it towards 'idle' - this must be done slowly - and as the twist-grip gets to the detent position listen for a soft 'click', at the same time look at the idle release button and you'll see slight movement (usually from side-to-side) - this is the first of two 'clicks'. Keep rolling and almost immediately you'll hear another louder 'click' and see the button pop out - this is the second 'click' and is the correct 'idle' position of the twist-grip. I'm surprised you haven't heard about this previously as the 'two-click' topic has been discussed over and over again in the past, I believe it was also featured in an earlier edition Rotorbreeze.
