  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.
