The speed control should be connected to the receiver and battery, and the transmitter should be adjusted as described previously. The profiles are selected by entering the programming mode.
DRIVING YOUR MODEL Now it’s time to have some fun! This section contains instructions on driving and making adjustments to your model. Before you go on, here are some important precautions to keep in mind. • Allow the model to cool for a few minutes between runs. This is particularly important when using high-capacity (2400mAh and above) battery packs that allow extended periods of running. Monitoring temperatures will extend the lives of the batteries and motor.
DRIVING YOUR MODEL RUNNING IN WET CONDITIONS Your new Traxxas model is designed with water-resistant features to protect the electronics in the model (receiver, servos, electronic speed control). This gives you the freedom to have fun driving your model through puddles, wet grass, snow, and through other wet conditions. Though highly water resistant, the model should not be treated as though it is submersible or totally, 100% waterproof. Water resistance applies only to the installed electronic components.
DRIVING YOUR MODEL 7. Let the car stand or you may blow off with compressed air. Placing the car in a warm, sunny spot will aid drying. Trapped water and oil will continue to drip from the car for a few hours. Place it on a towel or piece of cardboard to protect the surface underneath. 8. As a precautionary step, remove the sealed receiver box cover. While unlikely, humidity or tiny amounts of moisture or condensation may enter the receiver box during wet running.
ADJUSTING YOUR MODEL Once you become familiar with driving your model, you might need to make adjustments for better driving performance Adjusting Gear Mesh Incorrect gear mesh is the most common cause of stripped spur gears. Your model includes a fixed gear positioning system to simplify the process and ensure proper gear mesh settings. Access the gears by removing the four 3x12mm button-head cap screws from the gear cover; remove the gear cover. Remove the motor/motor plate assembly from the chassis.
ADJUSTING YOUR MODEL Gearing Compatibility Chart: The chart below shows a full range of gear combinations acceptable for this model. This does NOT imply that these gear combinations should be used. Over-gearing (bigger pinions, smaller spurs) can overheat and damage the motor and/or speed control. Pinion Gear Spur Gear 70 55 19 3.68 - 20 3.50 - 21 3.33 - 22 3.18 - 23 3.04 - 24 2.92 - 25 2.80 - 26 2.69 - 27 2.59 - 28 2.50 - 29 2.41 - 34 - 1.62 35 - 1.
