Main Rotor Blade Tracking Adjustment
Caution: Be sure to maintain a safe distance from the helicopter (approximately 10–15 feet) and to
wear appropriate eye protection (such as safety goggles) 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
Pro 2 PNP . Main rotor blades that are out of track may cause vibration, instability, and loss of power . Although
each Blade CP Pro 2 PNP model is test flown and the blades are tracked at the factory, minor adjustments to
blade tracking may be required after blade changes, repairs, or pitch control link adjustments .
To check main rotor blade tracking and make any required adjustments, please note the following tips:
• 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.
• After powering the model on and allowing the 2-in-1 unit and gyro to arm and initialize properly,
bring the main rotor blades of your Blade CP Pro 2 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 approximately 10–15 feet
from the helicopter when checking the tracking of the main rotor blades.
• Once the main rotor blades have been brought up to speed, note which blade is running low and
which blade is running high (by the colored tracking tape).
• 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 lengthening its pitch control linkage. This is accomplished by turning one of the
Ball Link ends out by one-half to one full turn. Or, you can decrease the pitch of the high blade by
shortening the linkage.

Tail Rotor Proportional Mix Trimmer Pot Adjustment
After trimming the primary flight controls and becoming familiar with the handling of the model, you may also need
to adjust the tail rotor proportional mixing . The proportional trimmer pot adjusts the amount of tail motor to main
motor mixing .
After establishing a stable hover, quickly advance the throttle/collective stick upward to “pop” the helicopter up
a few feet in altitude while adding no rudder input . During the abrupt increase in altitude, note which direction the
nose of the helicopter may yaw/turn . If the nose of the helicopter does not yaw in either direction by a significant
amount, no adjustment is necessary . However, if the nose of the helicopter yaws to the left, you will want to
increase the amount of tail motor to main motor mixing . By turning the proportional trimmer pot clockwise (+), you
increase the tail motor/rotor rpm for a given main motor/rotor rpm . This increase in tail motor/rotor rpm will help
to push the nose of the helicopter to the right when there is an abrupt change in torque .
If the nose of the helicopter is trying to yaw to the right, decrease the tail rotor proportional mix by turning the
proportional trimmer pot counterclockwise (-) .
NOTE: You must always power down the 2-in-1 control unit before making adjustments to the
proportional mix trimmer pot. Any changes made to the trimmer pot will not take effect until the
2-in-1 unit is re-armed.
