Verify that you have all your parts against the included checklist.

Build the twin motor gear box using the Tamiya instructions included in the box. Build the motor to configuration "C" High Torque Mode (203:1 gear ratio).

Solder on the motor wires before installing the motors (with the LCHB motor controller - see for motor controller wiring instructions).

Cut out the wheels and center spinners and trim with a hobby knife (be careful). You will need 6 large road wheels with 6 center spinners, 2 large front free wheels with two center spinners and 2 large drive (live axle) gears. See picture below in step 3 for an illustration of these parts.

Paint the road and drive wheels if desired. Plastic color is orange - painted silver, gold, white or black is nice. You can spray paint it with a Krylon plastic paint or brush paint it with a standard hobby paint from your local hobby store.

To make painting easy, you can mount each piece on the spare hex shaft with the wheel and track kit. Alternatively, you can use wood shish-ka-bob skewers, they work nicely and you can paint them all at once.

Install Motor using two flat 1/4" Philips screws in the base/motor mounting hardware package using the included screwdriver. This will be a bit of a pain as the space is tight, the smaller your fingers the better. Align the motor mounts on the bottom of the motor with the first set of tapped holes by sliding the motor axles in the slots on the end of the ATR base.

You can also use a screw grabber to place the screw first, or a magnetic head screwdriver to get it started as well. This is much easier, but we couldn't include these in the kit. If you have no luck after tries, then put a small dab of white glue on the screw and then put it on the screwdriver and it should hold the screw in place while you drive it home.

Build tracks using every piece of track supplied and following the Tamiya track assembly instructions. A small needle nose pliers can help in this assembly.

Each track should be made up of 1 long piece, 2 medium pieces, and 2 small pieces.

Finally, connect up the two ends and then roll the track onto the wheels and sprocket.

Install Motor controller - see LCHB instructions for wiring connections. You can mount the motor controller in various places in the lower cavity of the robot. We have left this up to you since it is our experience that you might have different ideas about where to mount this small board. You should have a separate battery pack for your motor controller (motors), 4 AAs would be fine unless you have a high current (2A+) regulator on your robot brain controller.

Install 2nd Level Plate with Four(4) 1/4" Pan Philips screws from the base/motor mounting hardware using the included screwdriver. You might want to mount your battery pack in the lower cavity, if you do now would be the time.

You also might want to mount your standoffs for you brain board to the level plate before you mount the plate itself (easier, especially for the Parallax BOE).

Finally, as with all of our tapped holes, don't over tighten or force screws as you will strip the hole. But , if you do, use the extra hardware kit to affix a nut instead.

Mount YOUR ROBOT BRAIN BOARD using the included 4 philips 1/4" 4-40 screws from the robot brain mounting kit with the included screwdriver. (Parallax BOE Board pictured)

Route the cables thru any of the three sets of access holes you choose and plug the servos into the YOUR ROBOT BRAIN BOARD according to that boards instruction.

NOTE: If you are not using an OOBoard, you will need to fabricate a connector and wires for the control of the LCHB motor control.
