8. Troubleshooting Guide Question: I installed the batteries in my transmitter, but the power lights do not come on: Answer: - Check that the batteries are properly installed by checking the polarity (+ and -). Question: My radio has power, but I have no control: Answers: - Check to be sure the power switch is on and connected to the receiver. - Make sure the batteries are charged (Replace or recharge if needed.) - Make sure you are using the proper crystals. Question: My vehicle is glitching, or the servos and/or speed control is acting erratically: Answers: - Check that there are no radios operating on your channel. - Make sure your electric motor has capacitors and the comutator is clean and brushes are not worn out. Replace if needed. - Check for loose screws as metal-to-metal contact can cause interference. - Make sure your receiver antenna has not been damaged or cut. - Make sure the power wires are at least 2" away from the receiver. - Replace the crystals if needed. - If all fails, send the system in to be serviced, as there may be internal damage. 9. Warnings - Never operate your car or truck in a crowded street with traffic. - Always extend your transmitter antenna when in operation. - Always check the battery power indicator before use. - Do not operate two or more models on the same frequency at the same time. - Do not operate your model in the rain or run through standing water. - Do not operate your model within one mile of a radio control racetrack. - Do not operate your model while under the influence of drugs or alcohol. - Always turn on your transmitter first and then the receiver to prevent loss of control. - When collapsing your antenna, never push it from the top or it may bend. 10. Racers Tips - Slower is faster, Do not overdrive your car. A cleaner line around the track is faster than more top speed. Don't overshoot the corners. - Reduce your steering dual rate if your car is over-steering or "Loose", and increase the rate if your car is under-steering or "Pushing." - Add more drag brake (see Steering and Throttle trims) if your vehicle is "Pushing" into the corners. Move the trim the other direction so your car creeps forward slightly when the throttle is at neutral if your car is "Loose" when entering the corners. - Don't crash! It's better to take a more conservative line than flip over and have to have a turn marshal turn you back over. - The most important thing to remember is to have fun!

This battery is typically only used with a gas or nitro powered vehicles to supply power to the receiver. Connect as shown. - Note: If using an electronic speed control, it will supply the power to the receiver through the connector plugged into channel #2. - Be aware you should keep your receiver antenna at least 2" away from any power wires to prevent potential interference. - Route the antenna up an antenna tube as typically shown in your vehicles instructions. - Warning: Be sure not to cut off any excess antenna wire, as it will shorten your operating range. B) Servos - Your Aggressor SRX includes either an HS-311HD or a powerful HS-645MG high torque metal gear servo. - The HS-311 is suited for light electric vehicles steering and most 1/10th size nitro vehicles for throttle. It should not be used for steering in nitro powered vehicles or heavy monster trucks. - The HS-645MG is a high torque metal geared servo that is well suited for monster trucks and nitro powered vehicles. - When installing the servos, refer to the manual of the vehicle for proper installation. - Once your servos are correctly installed, make sure they are properly centered. To do this, remove the servo horns; turn on your transmitter, then the power to your receiver. - Note: Always remember to turn your transmitter on first and off last. Failure to do so may result in loss of control and damage to your servos and/or linkage. - When the power is on, check to make sure the servos are working properly. - Center the trim switches on the transmitter and replace the horns so that they are centered if necessary. - Be aware the servos may not be perfectly centered. This is okay. Just get them as close as possible, and then use the trims or sub-trims for fine-tuning. C) Battery - The AA receiver battery holder supplied with your radio should be used in a non-electric vehicle requiring two servos. - Connect the AA Receiver battery holder or a 4 / 5 cell NiCad or NiMh pack to the power switch supplied, and then plug the switch harness into the "Batt" channel of the receiver for power - You will not need this battery if you are using an electric car with an electronic or mechanical speed control with BEC. 6.
