User Manual

To set a sticky safety switch on the throttle channel, just select type as X, set the switch as THR
and the value as -100% (i.e., full low throttle).
In this case Channel 3 (i.e., the third servo socket on the Rx) is the throttle channel. When the THR
switch is positive then the sticky throttle cut is active.
To see how 'sticky' throttle cut works, long press EXIT to get back to the home screens. Press UP
or DOWN to find the home screen which shows graphically the travel of each servo. Operate the
sticks to verify which stick makes which servo output move. Move the Throttle stick to a middle or
high position and watch what happens when you flick the THR.CUT switch upward. The throttle
goes to low and is unaffected by further stick movements. With the stick at part throttle, flip the
THR.CUT switch down. If you chose Sticky T-Cut, the throttle stick still does not work. Move the
throttle stick down to low throttle and then move it back up and the throttle stick now works as it
should. Thus you have a safety switch for the throttle which ensures that you cannot operate the
throttle until the throttle stick has returned to zero throttle.
Binding
You are now ready to bind your receiver to the transmitter according to the instructions of the
manufacturer of the module and receiver. Binding is the process of having the receiver memorize
the unique ID number of the module so it will respond only to your transmitter and not to any others
that might be turned on.
For DSM2/DSMX protocol receivers, binding also sets failsafe, so be sure your throttle is low when
you do it. Other radios set failsafe differently. Please read the instructions!
Checking Operation
After binding, turn the transmitter and receiver off and back on. Note that except when binding, the
transmitter should be turned ON first and OFF last. Check that all the controls move in the correct
directions.
In particular, for an electric model, check (very carefully, preferably with the propeller removed!)
that the electronic speed controller (ESC) arms itself and then operates correctly. If not you may
have to reverse the throttle channel. Note that failure of the motor to start or respond correctly to
the throttle stick is nearly always a matter of ESC calibration, rather than radio settings. Read the
ESC manufacturer’s instructions carefully before plugging in or turning on!
If you need to change the direction of a channel, go to screen 6/13, Limits. Move DOWN to the
channel involved and RIGHT to the last column. To reverse the channel, press MENU once to
change ‘---‘ to ‘INV’ for Invert. If you need to change other channels, you move UP or DOWN.
When done, press SHORT EXIT.
