PNEUMATIC SYSTEMS
9 Install the two air tanks.
9A. Install the larger air tank for the gear as
shown using silicone.
9B. Install the shorter tank for the brakes as
shown to the fuselage wall above the intakes.
Alternatively, you may use only the larger
tank, along with a single filling port. You
should be able to get four or more retract
cycles, along with some braking left over,
from the single large tank. Remember, you
really only need ONE cycle per flight! It's up
to you whether you want one tank or two.
Two tanks and completely separate air
systems for brakes and retracts make some
people feel more comfortable.
10 Use CA to assemble the two laser cut air
valve mounts.
11 Install the air valves to their mounts, add a
ball link to each valve. The ball links are not
mandatory, but they help reduce any side
loading on the valves, which cause leakage.
12 Install two quality miniservos and the two
air valves. Where exactly you want them on
the tray is up to you. It depends on what
other equipment you are using.
