AIR SYSTEM
Glue the air tanks with silicon behind the fuel
tanks. I have installed the 2 large tanks for
operation of gears ,doors and brakes.
Fit the 2 filler valves and 2 pressure gauges
onto accessory tray.
Plumb the landing gear, door and brake system
by using color air tubing. T all same color
tubing together until a single pipe emerge.
Route all 5 pipes to the accessory tray in front
of fuselage.
The air system will consist of :
Air up, Air down retracts (2)
Air up, Air down doors (2)
Air out brakes (1)
Air in (2)
Total of 7 pipes
There are 2 options available for the air system:
Mechanical Valves or Electronic Valves
For mechanical valves you will need
2 x 2 way valves and 1 x 1way valve
with 3 servos and sequencer.
The electronic EV5U will do all the
above in a single unit. This will make
installation much simpler and save
space.
Air leaks can damage your model! Please do a
thorough check for air leaks. Make sure the system
can hold pressure for at least an hour in the up and
down position.
Do not rush this installation.
