4.0 Initial setup

You MUST perform throttle range setup before the rst use of
the ESC. Remove propeller/pinion from motor while performing
initial throttle range setup.

4.1
Turn on transmitter and set throttle to maximum position
be sure that your throttle is set at 0% minimum throttle
and 100% at maximum throttle


4.2
Place the switch on the IR receiver to IRS (see section 5.0)
Connect battery to ESC. After few seconds you will hear 3
beeps come from the motor to indicate you are in
program mode.

4.3
With your throttle to maximum position place the switch
on the IR receiver to PPM. After a few seconds you will
hear 2 beeps come from the motor, once you have heard
these two peeps move your throttle to minimum position
within 10 seconds and hold throttle at minimum position.
Then you will hear 2 beeps indicating minimum throttle
position is set and conrmed. Your ESC will also arm after
you have set the minimum position. You only need to do
this once as throttle range will be stored in the memory of
the speed controller. You can reset the throttle range by
performing steps 4.1 to 4.3 again.
