RE: Skymaster MB-339
The front equipment tray has to be lowered,when using servos and air valves,for the brakes,retracts etc. The reason for this is because there is not enough clearance between the cockpit floor and the equipment tray. I made a new plywood tray and remounted it,30mm lower than what it was. Now there will be enough room for the servos and valves.
