First, confirm that the main rotor blades are positioned at 0° of pitch with the throttle/collective stick
in exactly the center position, when in the Idle Up/Stunt Flight Mode.
Then, confirm that the main rotor blades are positioned at approximately +9° to +11° with the
throttle/collective stick in its highest position. If they are not, adjust the Idle Up/Stunt Flight Mode
High pitch curve value (PHS), or the Pitch CCPM travel value (CP6), as required.
Finally, check to see that the main rotor blades are positioned at approximately -9° to -11° with the
throttle/collective stick in its lowest position. As long as the Idle Up/Stunt Flight Mode Low pitch
curve value (PLS) corresponds exactly to the Idle Up/Stunt Flight Mode High pitch curve value (PHS;
For example, 5% PLS corresponds exactly to 95% PHS, and 0% PLS corresponds exactly to 100% PHS,
etc), the main rotor blades should be positioned at the same amount of pitch in opposite directions
(for example, -10° at low stick and +10° at high stick).
Typically, we find that approximately -/+10° of pitch is a very good starting point for most pilots
when at low and high stick positions in the Idle Up/Stunt Flight Mode.
13.8 Note, some minor adjustments of the throttle and pitch curves may be required after making the
first and subsequent flights. This usually depends most on personal preference and/or flying style of
the pilot, as well as the performance of the power system and main rotor blades used.
13.9 Now that you have completed setup of your model, power down the transmitter and helicopter and
proceed with final assembly.
