8) Flying
1. Carefully recheck the directions of BOTH control movement AND stabilizer action – a mistake here can
have serious consequences! In summary: correct response to stick input is set in the transmitter, correct
response to a disturbance is set in the stabilizer.
2. Set Stabilizer Mode switch to OFF (Position 0). Red/Green LEDs are solidly on. Select Low Rate.
3. Take off and climb to a safe height.
4. Turn ON Gyro mode (Position 1). Expect Gyro mode to cause the model to fly more smoothly, resist wind
gusts, and be somewhat less sensitive to control inputs than with the stabilizer OFF. If there are any
unexpected reactions, immediately turn OFF the stabilizer (Position 0) and land to trouble-shoot.
5. If you see oscillation on any axis, slow down and land (or slightly turn down Master Gain, if you have it).
Turn the relevant pot(s) down (CCW) by an "hour" or so to reduce stabilization. To increase stabilization
on any axis, turn up the gain. See Adjusting Gain on page 10 of the Essential Instructions for detail on
adjusting gain and the Reference Guide for further advice.
6. Switch to Autolevel mode (Position 2). In Autolevel mode, you should find the model much more docile,
with a strong tendency to return to level when you neutralize the sticks. You will still have control, but
turns may require significantly more input and maximum bank and pitch will be limited. To increase
control authority, you can use High Rate and/or change to Advanced Autolevel mode in the stabilizer
configuration, which allows steeper bank angles (see Essential Instructions page 13). Be ready to switch
to OFF or Gyro if you encounter a problem.
If the model (with throttle set appropriately) does not maintain level flight in Autolevel mode, switch to OFF
or Gyro mode, land and reset Stabilizer Level and Stick Neutrals. Level is set by a toggle gesture during the
initialization period while the Green/Blue LEDs are flashing. Stick neutral is set by a toggle gesture after the
initialization period is complete. This is explained in detail on pages 11 and 12 of the Essential Instructions.
