PowerBox Systems MERCURY SR2 - Servo Assignment and Stick Input Learning

On the next screen you enter the number of servos you wish to assign to individual
control surfaces. The Assistant supports a maximum of three servos per control
surface. This means: if your model is tted with overall four aileron servos, enter 4
behind ailerons.
You will now see further screen displays which vary according to the data you have
already entered. The following illustrations show the aileron channel as an example,
based on the above data:
Now move the aileron stick at the transmitter: the PowerBox checks the input: in this
example four channels should move. Two for the ailerons and two for the tailerons.
The screen shows now which channels have been detected, and the outputs to
which you should connect the servos. Bearing in mind that your individual trans-
mitter’s channel sequence may not be as shown above, you may need to move the
transmitter stick briey and repeatedly until the detected channels appear after the
appropriate functions.
Repeat the procedure with the elevator and rudder functions. After this you will be
asked to enter the Gain channel for the iGyro.
You need to assign a channel with +/-100% travel to a rotary control at the transmit-
ter. Even if you have not connected an iGyro SAT, this action is recommended as it
will make it easier to retro-t the gyro.
If you have selected a thrust vector function, you will see a second query regarding
the sensitivity of the thrust vector control system. This is the method the Assistant
uses to set up the basis for a simple but effective method of adjusting gyro gain in
ight.
Note: If multiple servos are mechanically coupled to a single control surface,
disconnect the linkage to servos 2 and / or 3, as the servos are not yet matched
to each other, and you could stall them!
