D) Radio Frequency (RF) Indicator Light - The green light will only be on if the transmitter is sending a signal. E) Steering Dual Rate - Adjusts the overall travel of the steering servo. - Push the dial forward with your thumb for maximum steering (Maximum 125%). - Pull the dial back with your thumb to reduce the travel (Minimum 60%). - Use this to fine tune your vehicles handling for the surface conditions. - Use more steering travel for high bite surfaces and less for low bite surfaces.
K) Antenna - Always extend your antenna before turning your transmitter on. - The antenna may be removed by turning counter clockwise. - Warning: When collapsing your antenna, never push it from the top; it may bend. L) Grip Pad - The removable grip pad helps keep your hand secure on the radios pistol grip handle. - The Grip Pads are available in assorted colors and sizes to customize the look and feel of your radio.
3. Transmitter Battery installation - Press down on the battery cover and slide in the direction illustrated. - Remove the cover and install the batteries as shown. - Remember to be careful and pay close attention to the polarity of each cell you you could damage the transmitter. - Replace the cover; making sure it is closed securely.

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.
6. Main Edit mode This menu allows you to set up the initial settings of the model, and will typically only be accessed once unless setting up a new model. The main edit mode screens will appear in the following order: 1. Model Naming 3. Channel 3 switch set 2. Model Reset 4. Timer Programming A) Entering the Main Edit Mode - Access the programming menu by holding the "FUNC" (function) button down, and then turning the transmitter power switch on. Release the function button.
D) 3rd Channel Switch Select: AUX - After entering the Main Edit mode press the "FUNC" button to scroll to the 3rd Channel Switch Select menu. - Push the "DATA" + and - buttons to Select either "Linear" or "Shift". - Linear is activated via the trim tab on the right side of the steering column and can be moved to any position you select. This is typically used for mixture control in nitro boats, but you can use it for other functions if needed.
7. Programming mode This programming menu allows you to access the settings that you would typically change to set up your vehicle or change models. The Programming mode screens will appear in the following order: 1. Model Select 2. Sub-Trims 3. EPA 4. Exponential 5. Servo Reverse Programming - Access the menu by holding the "FUNC" (function) button down for three seconds while the transmitter is already on. A) Model Select MDL - Press the "DATA" + or - buttons to Select the model to be used.
C) EPA (End Point Adjustment) EPA EPA EPA ST TH AUX - After entering the Programming mode press the "FUNC" button to scroll to the EPA menu. - The current settings will show on this menu. - STEERING EPA - "Steering" will appear first. Use the "DATA" + button to adjust the EPA setting higher or the - button to adjust it lower. The factory setting is 100%. You can increase the end points up to 125% or down to 0%.
D) Exponential EXP EXP ST TH - Negative steering exponential will make the vehicle less sensitive to small inputs and Positive expo will make the vehicle more sensitive. Typically you will only use negative expo for steering but you should experiment with this setting to see what suits your driving style the best. -30% is a good place to start. - Use negative expo for the throttle to broaden the power band and positive expo to increase the "punch".
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.
