Blade Tracking Adjustment
Caution
: Be sure to maintain a safe distance from the helicopter (10–15 feet) when tracking the main rotor
blades.
Blade tracking is a critical element to the flight performance of just about any helicopter, including the Blade
CP. Main rotor blades that are out of track may cause vibration, instability, and loss of power due to increased
drag. Although each Blade CP model is test flown with blades tracked at the factory, minor adjustments to blade
tracking may be required after blade changes, repairs, or pitch curve adjustments.
For proper main rotor blade tracking and adjustments, please read the tips below:
• Before proceeding with the test flight of a new model or any model to which changes or repairs have been
made, be certain that the main rotor blades have been properly installed and secured. The main blades should
be tightened so they can pivot in the blade grip when moderate pressure is applied. Never allow the main
blades to swing freely in their grips.
• Following the proper arming and start-up procedure previously listed in “4-in-1 Control Unit Description, Arming
and Adjustment” section, bring the main rotor blades of your Blade CP up to speed. You can check the blade
tracking either on the ground or in the air at eye level. It might be a good idea to have an assistant on-hand
to help sight the blades. Again, be certain to maintain a safe distance of 10–15 feet from the helicopter when
checking the tracking of the main rotor blades.
• Once the main rotor blades have been brought to speed, note which blade is running low (by the colored
tracking tape).
• You can then power the helicopter down and increase the pitch of the low blade by turning its Pitch Control
Link end in one turn at a time. Repeat the process to check the blade tracking and make adjustments until both
blades run in track.
