Thanks for the information, I was told by my Tec Rep here that there was a new pop out to be available this spring or summer. we have also been told that to bleed the system would clear up the problem. We have bled the system which seem to help for a flight or two but the problem returns.
I'm installing the 4th axis into 6 aircraft at the moment, heads up that some of the aircraft have been pre-wired but some have not. The BT call to run the new wiring, save some time check if the wiring is there before you pull the dash apart.
