AIR SYSTEM There are 2 options available for the air system: Mechanical
or Electronic. For mechanical you will need 4 x 2 way and 1 x 1way valve with 5
servos and sequencer. For electronic you will need 1 x EV5U and 2 x EV2U.
Glue the air tanks with silicon glue.
I have glued the smaller tank underneath fuel tank
and the larger tank underneath the turbine. Both
centre in the fuselage.
The 1 large tank is for operation of gears and
Doors and the smaller tank for brakes.
You will require an additional tank for operating the
speed brake. Glue this tank next to big tank
underneath turbine.
Fit the 3 filler valves and 3 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.
Fit electronic EV5U valve in front main tank.
Route all 5 pipes to EV5U.
Plumb speed brake.
Secure 1 x 2way electronic valves adjacent to
EV5U. This will be for speed brake.
The air system will consist of :
Air up, Air down retracts (2)
Air up, Air down doors (2)
Air out brakes (1)
Air up, Air down speed brake (2)
Air in (3)
Total of 10 pipes
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.
