4.
With end points (limits) and control rates at 100%, check that control surface throws are at the
recommended maximums for the model and adjust linkages if necessary. Note that adjusting throws in
the transmitter will not affect stabilization responses, so throws need to be set mechanically to give the
stabilizer an appropriate amount of control; the exact amount is not critical, as gain will later be used to
adjust stabilization, but it should be reasonably close.
7. Test stabilization response and directions
Turn the three on-board gain adjustment pots fully clockwise to maximize action.

Set the Stabilizer ON/OFF
switch to ON (green Status light ON). Sharply move the plane in each of the three flight axes and verify that the
control surfaces move momentarily to oppose the disturbance. See diagram below.
HINT
: If you find it hard to see the response direction, put your finger on the hinge line of the control surface. It
is easier to feel a short pulse than see it.
The diagram shows how the surfaces should respond with a momentary pulse to movement of the model about
each axis. When the model is rolled sharply to the right, the right aileron should go down and the left aileron up
to resist the displacement. Likewise, when the model pitches nose-down, the elevator should go up to
compensate. And when it yaws nose-right, the rudder should go left.
Remember that this receiver provides rate stabilization, not auto-levelling. Thus, when testing, the control
surfaces will only be displaced while the model is being disturbed. As soon as angular motion stops, they will
return to neutral. Hence, look for quick twitches of the control surfaces in the right directions, not prolonged
control offsets.
THE FOLLOWING IS VITALLY IMPORTANT
:
If stabilization moves any of the surfaces the wrong way (i.e., to increase the disturbance), your model may be
uncontrollable (until you switch off stabilization)!
To correct this, change the appropriate stabilization response direction indicated by the 3 green LEDs: G1
(aileron), G2 (elevator) or G3 (rudder). Instructions on how to program the receiver to do this are in Step 4 on
page 6.

If you are using channel 8 for Master Gain, set it temporarily to the middle or high end of its range.
