- Split the motors between outputs 1-5 and 6-10 to
avoid internal fuse problems
- Connect only one motor to each of the speed
control channels (1 and 10). Connecting two
motors to a single channel may cause problems.
- The keyed edge of servo connector (white wire)
goes towards center of Cortex.
- Leave the battery adapter installed; disconnect at
the powerpole connector.
- Connect the 9V backup battery to avoid losing the
synch with the Joystick and/or programming when the
main battery voltage gets too low. Turning the unit
off under good main battery conditions does not
cause a loss of synch or programming.

- Solidworks Model
- Batteries should last about 2 hours.
- Don’t let the batteries get too low, or you may
have to re-synch the Cortex & Joystick
- Joystick can be left off when tethered to Cortex
using the USB A-A cable.
- If things get too messed up, press and hold the
“config” button until the LEDs flash, then turn off
the Joystick. Connect it to the Cortex using the USB
A-A cable, then turn on the Cortex (only) and wait
for the units to re-synch.

- Joystick Calibration Procedure
- Use the “Fast Charge” switch position for the 3000
mAh Ni-MH batteries.
- In the fast charge position, recharging a dead
battery will take about 105 minutes.
- During the 6-week build cycle, use the batteries
until they are discharged before recharging.
On competition day, keeping the batteries charged
(without full discharge) shouldn’t hurt their
performance since Ni-MH batteries are less affected
by battery “memory.”
AAA Battery Charger
- Install the batteries in the charger before
applying power to the charger.
- The recharge time will be over an hour for fully
- A red light indicates the battery is being
charged. The light will change to solid green
when the charge is complete and the trickle charge
- A flashing red light indicates a bad battery.
- If you press the blue button within 1 minute after
applying power to the charger then the discharge
cycle will start. A flashing green light indicates
that the battery is being discharged. After the
discharge cycle is complete for all batteries, the
charge cycle will start automatically.
