Final Adjustment of Motor Arm Position & Tension
i.
The motor arms are designed to intentionally pivot at the single mounting
point.
ii.
The motor arm is typically mounted at about 60 degrees from the main
frame (see picture below). This is a good starting point for most applications.
Verify that your propeller will not interfere with the main frame standoffs.
The arm length is designed to accept a 5 inch prop without interference.
There should be no noted “slop” and the arms should feel firmly seated in
position, yet should pivot with moderate force. Tighten/loosen the arms as
necessary so that they are firmly seated but can pivot with moderate force.
Do not over-tighten
to cause excessive dimpling of the laminate or possibly
sheering the aluminum threaded rod.
PROPER ANGLE AND ANGLE TEMPLATE
iii.
Repeat the above steps when realigning the arm(s) after a crash. Inspect for
damage to the arm or frame. Always repair or replace broken structural
parts prior to use.
iv.
The positioning of the motor arms can be varied from 60 degrees to affect
flight characteristics, including the location of the center of gravity (CG).
