6) Stabilizer Setup.
Always remove the propeller or disconnect the motor before working with the battery plugged in.
1. Place the model on a firm base and in a “level flight” attitude – typically 2-3 degrees nose up.
2. With the receiver already bound, power up first the transmitter and then the receiver.
3. As soon as the Green/Blue LEDs start flashing, toggle the switch that controls Stabilizer Mode. “Toggl ing ”
means rapidly flicking the switch from one extreme to the other at least 3 times. If successful, first the
red LED on top of the unit will light, then the green light will flash four times
4. Wait for the receiver to complete its initialization. Do not move the model during this time –
approximately 10-15 seconds.
5. With the stabilizer mode set to OFF (Red /Green ON solid), verify that all control surfaces travel in their
correct directions when the transmitter sticks are moved. If necessary, change the relevant Reverse
setting under Servo Setup in the transmitter. At this time check that all control surfaces are centered.
6. Set the stabilizer mode to Autolevel (Red/Green alternately flashing slowly). Rotate the model about the
pitch and roll axes and watch for the ailerons and elevator to deflect and stay deflected when it is not
level.
7. The directions of the stabilizer action on the aileron and
elevator axes MUST be as follows:
If the model is rolled to the right: right aileron goes DOWN
and the left UP to level the model.
If the nose of model is pitched down: elevator goes UP to
restore the model to level flight.
The rudder is also stabilized but reacts differently:
If model is yawed (rotated) to the right, the rudder pulses
LEFT momentarily to resist the displacement, then returns to
neutral.
If any response is incorrect, use the appropriate switch J1, J2 or J3 to reverse the action and test again. The
labels On and Off have no specific meaning for these switches.
7) Transmitter Setup.
1. If available, set Master Gain to the midpoint (i.e., 0% on the transmitter’s monitor screen for channel 8).
If your transmitter has less than eight channels, Master Gain is fixed at 1x, which is 0%, and you can skip
this.
2. Check that the flight control trims are set to zero. If necessary, use a little Sub-trim to align the servo
arms at right angles to the pushrods. Adjust mechanical settings to center the control surfaces.
3. Te st fai lsafe by turning off the transmitter with the motor running and the prop removed or the model
restrained. (Do this failsafe test on the ground, NOT in flight!).
Make sure you know how to find the Stabilizer Mode switch without having to look down at the transmitter
and that you know how to turn it OFF quickly.
It is recommended that you set up Dual Rates on the transmitter with Low Rate being about 70% and High
Rate 100%. Use mechanical adjustments and/or servo travel to set control throws to those recommended for
the model.
You may also wish to add 20% Expo, or somewhat more, to soften control responses around neutral, but
keep in mind that stabilization has an expo-like effect.
