Buzz Assembly
The Buzz comes nearly completely assembled out of the box, only required to install
the propellers and FPV antenna.
Propeller Direction and Mounting
There are 2 spinning directions for the propellers, Clockwise (CW) and Counter-
Clockwise (CCW). When Buying a set of propellers, 2 CW and 2 CCW will be given.
The blunt leading edge indicates the direction the propeller is supposed to rotate as
compared to the sharp trailing edge. When mounting propellers please make sure
the correct orientation shown in the diagram below.
Caution: Failure to mount the propellers in the correct orientation will cause Buzz to
not fly correctly and with no control. Please double check for the correct orientation.
1. Push the propeller down the 5mm shaft.
2. Tighten the M5 lock nut and secure it.
3. Periodically check nut tightness to ensure it will stay tight during flight.
Propeller Type
There are two different propeller types given with buzz: Avan Flow 5x4.3x3 and Avan
Scimitar 5x2.6x3. These two props will give two different flight styles. The Avan Flow
5x4.3x3 flies very fast and operates well at higher speeds with the compromise of
lower flight time. Avan Scimitar 5x2.6x3 flies slower but with an increase of flight
time.
Antenna Mount
Mount the provided pagoda antenna to the back of the Buzz where the SMA port
mounts. Periodically check tightness to insure good video quality during each flight.
