Main Rotor Blade Tracking Adjustment

Caution: Be sure to maintain a safe distance from the helicopter (2025 feet) when tracking
the main rotor blades.Blade tracking is a critical element to the flight performance of just
about any helicopter, Main rotor blades that are out of track may cause vibration,
instability, and loss of power due to increased drag. Although the main rotor blades of
each e-razor 3D helicopter are tracked at the factory, minor adjustments to blade tracking
may be required after blade changes,linkage adjustments or repairs.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 rotor blade mounting bolts should be tightened so that the
blades can pivot in the blade grip when moderate pressure is applied. Never allow the
main rotor blades to swing freely in their grips.
After powering the model on and allowing the ESC and gyro to properly arm and initialize,
bring the main rotor blades of your e-razor 3D up to speed. You can check the blade
tracking either on the ground or in the air at approximately eye level. It might be a good
8
idea to have an assistant on hand to help sight the blades. Again, be certain to maintain
a safe distance of (20-25 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).
T he helicopter with main rotor blade all have pitch control links .you only need to turn the
control link to achieve the blade tracking adjustment .certainly the best way is to adjust
both pitch control link at the same time. If you made small adjustment on one rotor blade
,the main rotor blades are still out of track ,you need to adjust another blade ,and repeat
the process to check the blade tracking and make adjustment until both blades run in
track .with proper adjustment ,the helicopter will fly stably and smoothly.

IDLE MODE PITCH ADJUSTMENT
In order to upgrade the e-razor or repair later, and adjustment helicopter pitch ,here ,we
introduce some adjust pitch way. We advise cut off the link between battery and motor.
prevent helicopter running when you operating .
1 ,Put the transmitter all sticker trimmer in midder, switch F. MODE to IDLE ,put throttle sticker
in midder station.
2, Adjustment 3 pitch servos's arm to level. and adjustment helicopter razor shape arm ,SF
arm to level ,if you confirm now the main blade pitch degree 0,---finished IDLE mode pitch
adjustment.
NORM MODE pitch adjustment
1.Switch transmitter F MODE to NORM MODE, down the throttle sticker to zero.
2.Adjust the knob C, let the pitch degree -2.
