3. Transmitter Battery Installation
5. Receiver and Servo Connections
- Press down on the battery cover and slide in the direction illustrated.
- Remove the cover and install the batteries as shown.
- Be careful to pay close attention to the polarity of each cell or the transmitter will not operate.
- Replace the cover making sure it is closed securely.
4. Recharging Batteries
- You must install individual AA size rechargeable batteries.
- Only use Nicad or NiMh type. (Alkaline batteries are not rechargeable).
- Connect the optional Hitec CG-25 overnight wall charger to the charging jack located under the
switch to charge. Depending on the capacity of the battery;
- A full charge on a typical Nicad will take 12-16 hours.
- A full charge on a typical NiMh will take 24-36 hours.
A) Receiver:
- The receiver in your Aggressor system includes a BEC (Battery Eliminator Circuit), which
eliminates the need for a separate receiver battery when used with a mechanical or electronic
speed control. Power input should be no more than 8.4V (7 cells)
- You can use a separate receiver battery if required for your particular model. Connect as shown.
- Be aware you should keep your antenna at least 2" away from any power wires to prevent interference.
- Run the antenna up the antenna tube as 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:
- When installing the servos, refer to the manual of the vehicle for proper installation.
- Once your servos are correctly installed you will need to make sure they are properly centered.
To do this, remove the servo horns and turn on your transmitter, then the power to your receiver.
Remember; always turn your transmitter on first and off last. Failure to do so may result in loss of
control and can damage your servos and/or linkage.
- Now that the power is on, check that the servos are working properly.
- You will now center the trim knobs on the transmitter and replace the horns so that they are centered.
- Be aware they may not be perfectly centered; this is OK, just get them as close as possible.
Then use the trims for fine-tuning.
C) Battery:
- The AA receiver battery holder supplied with your radio should be used in a non-electric
vehicle that requires two servos.
- Connect the AA Receiver battery holder to the power switch supplied, and then plug the switch into the
"Batt" channel of the receiver for power.
- You will not need to connect this battery if you are using an electric car with an electronic
speed control or mechanical speed control with BEC.

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: This is not shown in the image
- Adjusts the overall travel of the steering servo.
- Push the dial forward with your thumb for maximum steering.
- Pull the dial back with your thumb to reduce the travel.
- Use this to fine tune your vehicles handling to the track conditions.
- Use more steering travel for high bite tracks and less for low bite tracks.
D) 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 a
notch or two 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 go of the trigger. Be aware that too much brake may affect the servo end point preventing
maximum power.
- 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.
E) Tuning Cover:
- Remove the tuning cover to access the servo reversing switches.
- This is also an interchangeable part with assorted colors and designs to choose from so you may
customize the look of your radio. See "Options" for more info.
F) 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.)
G) Battery Cover:
- Remove to change batteries.
H) 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!
I) Grip Pad:
- The removable grip pad helps keep your hand from slipping on the radio pistol grip handle so
you have better control of the vehicle.
- It is also available in assorted colors and sizes to customize the look and feel of your radio.

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.
- 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.
- 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!
