The owner took them off because his air system was not working strong enough and the air passing around the doors when gear down prevented the gears from retracting completelly before the UP valeve closed the gear doors. He is know adding an extra air tank as after testing we found that the system worked good when it was just filled up and preassure was at its max. Also a bit of adjustment to the UP valve is needed so it keeps the gear doors opened a bit longer.
