Problems:

Once you have identified the problem part, do not try to repair it yourself;  contact our KitGuy(s) for replacements and/or repairs.  You can also contact the KitGuy(s) if you've been unable to locate the problem. Please note, you must include the word "sabest" (no quotes required) in the subject line for messages that you send to kitguy; this is used to filter messages to avoid the large amount of SPAM that we get at the kitguy address.

Do you know how to solder?  Take a look at the Soldering Guide for some helpful hints with your BEST soldering tasks.

Cortex

• 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.

Joystick

• 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.

Speed Controller

• Connect only one motor per speed controller.

Small Motor

Motors

• Use the connectors supplied in the consumable kit with the motor; please don’t solder to the leads.
• Mount the motor using 8-32 screws that install on the face of the motor. Be careful of the insertion depth; the maximum depth is roughly 1/8" for the small motor, and roughly 1/4" for the large motor.
• Since the motor is not sealed, keep the motor away from any metal shavings or other debris.

Smart Charger

• 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 discharged batteries.
• 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 starts.
• 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.
