Air Retracts storage issues.
I have been unable to fly my jet for the past three months due to other matters, but this morning decided to prep it for flight again, it has only had one flight I should add. It was stored with the retracts up and some pressure in the system about 50 psi. The retracts would not come down either by manually pressing the buttons on the valve or from the Tx. After pressurising them back to 110psi they came down but worked intermittently for a while until they obviously freed off and now seem back to normal. Silly question time, is there a best way to preserve the system when not in use ? and is there anything to be used in terms of cylinder lubrication if they are laid up for some time? advice appreciated, thanks.
