ENGLISH
This ajustment permits to keep the pump operative and to prevent it from to stopping too early,
before the landing gears are completely closed or completely open.
The standard pull-in/pull-out time is abt. 10-20 seconds. However, to avoid a complete unloading
of the battery, the electronic control unit is set for a more extended pump stopping time, up to 45
seconds.
The L/G can pull-in and out eight to ten times with a 1800 mAh cell-pack. For proper system
working make sure the battery is always full-charged.
To complete the initial filling of the system’s tubing, it is necessary to let the landing gear work
several times either ways, to get full air relief from the pipes and the cylinders. In our system no
relief valve is necessary because air, during the initial pull-in/pull-out cycle, is pushed to the oil
tank and there stored once and for all.
If the oil level in the tank goes too much down fill up to avoid air intake through the relief
tubing.
This oil system requires no maintenance, provided it has been properly installed, and it is free of
leaks. Check the oil level in the tank from time to time. Once the tubing system is completely full,
the oil must fill half the tank. It is advisable, prior to flying always to check the good conditions
of the system, by running a L/G opening/closing cycle.

TWIN-VALVE WING/FUSELAGE JOINT FOR OIL SYSTEMS
(to purchase separately)
This type of joint permits to assemble and separate two sections of whaterver oil system for breaks
or for landing gears with no leakage or pressure loss.
The joint contains two automatic valves: when the central ring that connects the two sections in
unscrewed as to separate one section from the other, the valves close automatically, so barring the
way to oil or pressure.
When, on the contrary, the two sections are re-connected, and screwed together, the valves will
open again to permit oil or pressure circulation.
This joint can be used on models having the main landing gear fixed to the wing or in which the
half-wings can be dismounted from the fuselage.
In these models the whole oil system can be entirely installed into the fuselage, and the wing, or
the half-wings can be easily removed still keeping in place the respective landing gear without
any leakage from the hydraulic system.
