STEP 7-5 FINAL SERVO AND RADIO SETUP
Caution: Be sure to maintain a safe distance of at least 7 meters from the helicopter when observing the track of the main rotor disc.
Blade tracking ensures that both of the main blades are set to the same pitch angle, and if done correctly will make your helicopter smooth in operation.
Caution: Be sure to maintain a safe distance of at least 5 meters from the helicopter when observing the tracking
of the main rotor disc.
Adjustment should be done using the following method.
Increase the pitch of the low blade by extending its connecting link by
one full turn. Note you can only make this adjustment in increments of
one full turn otherwise you will be trying to fit the link on to the ball joint
the wrong way round. (The "RJX” on the link must face outwards).
Check the tracking again and if the tips of the rotor blades are now in
line, you have finished and are ready for your first flight. If the blades
still require adjustment then reduce the pitch of the high blade this time.
Repeat this procedure until the blades are tracking true.
A check of the tracking should be part of your pre-flight routine. If it has
suddenly gone out it is an indication that something is wrong and needs
immediate investigation.
