Service Department 12115 Paine St. Poway, CA 92064 Please include your name address and telephone number along with a brief description of the failure or the work that you are requesting to be done. A) Transmitter: - Current drain 180mA - Modulation: FM - Power supply: 8AA alkaline, Nicad or NiMh batteries - Frequencies: 27mhz (6 channels), 75mhz (30 channels) B) Receiver: - HFS-03MM - Modulations: FM - Power Supply: 4.8V- 6V - Weight: 0.6oz - Size: 1.5 x 1.0 x 0.6" - Current drain: 30mA +/- 0.3mA D) Accessories: - "Brake Pad" This small piece of foam can be attached to the brake lever on the trigger to take up any space between your finger and the lever for a custom fit. E) Options: - Red, Blue and Black colored grip pads in large and small sizes (Sold separately). - Tuning covers available in Red, Blue and Clear, as well as custom designs in Silver Carbon and Camouflage (Sold separately). C) Servo: - HS-325HB - Voltage range: 4.8 - 6V - Speed: 0.15sec/60 degree (6V) - Torque: 51in/oz (6V) - Weight: 1.5oz - Size: 1.6" x 0.8" x 1.4" 1. System Specifications 45 J) Antenna: - Always extend your antenna before turning your transmitter on. - Your antenna may be removed by turning counter clockwise. - Warning: When collapsing your antenna, never push it from the top or it may bend! K) Grip Pad: - The removable grip pad helps keep your hand secure on the handle for better control of the vehicle. - The Grip Pads are also available in assorted colors and sizes to customize the look and feel of your radio.

Throttle Trigger Battery Cover E) Steering and Throttle trims: - The trims are used to fine-tune the point where the servo returns to center. - Use the ST-TRIM so your vehicle will go perfectly straight when the steering wheel is centered. If you move the trim to its maximum and the vehicle does not go straight, move the servo horn on the servo output spline or adjust the linkage to fix the problem. Ideally, the servo horn will have equal throw in each direction. - Use the THR-TRIM to adjust the "Drag Brake"; this is the amount of braking that occurs when you let of the trigger. Be aware that too much may affect the servo end point preventing maximum power. Increase the throttle EPA is this happens. - Tip#1: Do not mount the horn on the servo until you turn on the radio and center the trims. - Tip#2: Always trim your vehicle before you run or race. F) Tuning Cover: - Remove the tuning cover to access the servo reversing switches and End Point Adjustments (EPA). - This is also an interchangeable part with assorted colors and designs to choose from so you may customize the look of your radio. See "Option Parts" for more info. G) End Point Adjustments (EPA): - Used to set the servo end points for the steering and throttle. H) Servo Reversing switches: - These are used to change the direction of the servo travel for proper control when activated. - If you steer right and the wheels go left, change the "ST" switch from NOR to REV or REV to NOR if needed. The same applies to the throttle. - (Note: You should not need to change the "THR" switch from NOR if using an Electronic Speed Control.) I) Battery Cover: - Remove to change batteries. ST-EPATHR-EPA LFTRGTTHRBRK NOR - REVNOR - REV STTHR TOP FRONT 2. Transmitter Functions and Operations A) Power Switch: - Slide the switch up to turn on the transmitter, and down to turn it off. - Warning: Always turn your transmitter on before switching on the receiver switch. This will help prevent accidental runaways. B) Battery Indicator LED's: - Green is mid - high power - Amber is mid power (You should replace or charge your batteries very soon.) - Red is low power (Stop driving!) C) Steering Dual Rate: - Adjusts the overall travel of the steering servo. - Push the dial forward with your thumb for maximum steering. - Pull the …

4 Tuning Procedures 1. Attach 12.0 Vdc power supply 2. Using a Spectrum analyzer and a short-range pick-up antenna, look for 75MHz signal with sufficient scan width to see 30-150 MHz spurious. 3. Adjust T1, T2, T3, T4, and T5 for maximum output at operating frequency and minimum output at any harmonics. 4. Repeat step 6. 5. Check for minimum emissions from 30 to 760 MHz. Inspection Specifications Frequency: FO +1KHz Modulation: 2.8KHz FM RF Power: 400 +/- 50mW Frame Time: 17~21mS General Description The Aggressor is a low power, non-voice, transmitter intended for remote control of ground based models in the 75MHz band. The unit is held with two hands in front of the body. The equipment employs a vertical polarized antenna, directly mounted on the unit and meets Paragraphs 95.645, 95.647, 95.649, and the technical requirements established in the Report & Order in PR Docket 90-222. Circuits and Devices to Stabilize Frequency Transmitter output frequency is determined and stabilized by crystal-controlled oscillator. Circuits to suppress Spurious Radiation Final RF amplifier spurious emissions are attenuated by a “PI” matching network consisting of L2, C18, C19, C23, C17, C13, C14, T1, T2, T3, T4 and T5.
