1. Locate the large and small air brakes. The air
brakes are an optional part. There are two different
size air brakes supplied with the 4-Site. If you
are interested in flying more aggressive 3D style
maneuvers you may want to leave these off. If you
fly mainly in a large indoor facility, then you will
want to use the smaller air brakes. If you fly in a
smaller area like a one court size gym, then the
larger air brakes will slow the 4-Site down more.
You may choose to try all three variations. Do
this by just lightly tack gluing the air brakes on at
first. Choose the set of air brakes that suits your
particular flying location and flying style.
2. Use foam-safe CA to glue the air brake to the
outer strut. Use a square to align the air brake with
the outer strut as shown.
3. Use two 3

-inch (80mm) carbon rods to
support the air brake and keep it from changing
angle. The carbon rods are glued using foam-safe
CA. Use a square to check that the air brake is still
square to the outer strut before the CA fully cures.
4. Repeat Steps 2 and 3 to install the remaining
matching air brake.
