• After confirming which blade is running low and which blade is running high, power down the
helicopter in order to make any necessary adjustments to the linkages. You can increase the pitch of
the low blade by shortening the “mixing arm to inner swashplate linkage.” This is accomplished by
turning one of the Ball Link ends in by one-half to one full turn at a time. Or, you can decrease the
pitch of the high blade by lengthening the same linkage.
Note: The blade you choose to raise or lower when making tracking adjustments will depend on
the pitch of each blade. Because both rotor blades should be as close to 0 degrees as possible
when Throttle Hold is activated (DO NOT attempt to check for 0 pitch in the Normal or Stunt/Idle
Up flight modes) and the throttle/collective stick is in the middle position, you can easily identify
which rotor blade to adjust. If one blade is “lower” than 0 degrees, raise it to match the other
blade. If one blade is “higher” than 0 degrees, lower it to match the other blade.
Typically, not much adjustment should be necessary to properly track the main rotor blades. If
significant adjustments are required, be sure to double-check the length of both mixing arm to inner
swashplate linkages (they should be close to the same length). You should also check the blades for
any warps or twists. In most cases, you should be able to get both blades tracking perfectly in the
same plane. However, due to slight variations in the ball links and threaded linkage rods/pushrods
it may not always be possible to achieve absolutely perfect blade tracking. Don’t worry, as the
helicopter should still perform well as long as the blade tracking is adjusted as closely as possible.
Flybar Paddle Tracking Adjustment
While main rotor blade tracking is a critical element of flight performance, proper flybar paddle
tracking and positioning is also important in maintaining proper control response and vibration-free
operation.
To check flybar paddle tracking, positioning and to make any necessary adjustments, please note the
following tips:
• Confirm that both flybar paddles are equally spaced from the ends of the flybar paddle control
frame arms. If they are not equally spaced, adjust the position of the flybar by loosening the two
setscrews located in each paddle control frame arm, then sliding the flybar from side to side until
they are.
• Confirm that both flybar paddle control frame arms and rods are parallel to one another. It may be
necessary to loosen the four screws that hold the paddle control frame assembly together in order to
adjust the position of each part.
• Be certain that both flybar paddles are parallel to the flybar paddle control frame arms. If they are
not, loosen the setscrews in the flybar paddle mounts/adapters and twist the paddles until they are
properly aligned and parallel with the paddle control frame arms.
• I f you have made certain that both flybar paddles are parallel to the paddle control frame arms, they
should now be parallel to one another. If they are not, take your time making adjustments in order
to ensure that both flybar paddles are positioned parallel to one another and the paddle control
frame arms.
• Once you have properly positioned and aligned the flybar paddle control frame parts and the flybar
paddles following the tips above, be certain that all screws and setscrews are firmly secured.
