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.  
This can cause long-term problems with the sensitive electronics 
in the receiver.  Removing the receiver box cover during storage 
allows the air inside to dry. This step can improve the long-
term reliability of the receiver. It is not necessary to remove the 
receiver or unplug any of the wires.

9. 

Additional Maintenance

: Increase your frequency of 

disassembly, inspection, and lubrication of the following items.  
This is necessary after extended wet use or if the vehicle will 
not be used for an extended period of time (such as a week or 
longer). This additional maintenance is needed to prevent any 
trapped moisture from corroding internal steel components.

• 

Stub axle housing bearings

: Remove, clean, and re-oil the 

bearings.

• 

Titan motor

: Remove the motor, clean with aerosol motor 

cleaner, and re-oil the bushings with lightweight motor oil. Be 
sure to wear eye protection when using spray aerosol cleaners.

RECEIVER BOX: 

MAINTAINING A WATERTIGHT SEAL

Removing and Installing Radio Gear

The unique design of the receiver box allows the removal and 
installation of the receiver without losing the ability to maintain a 
watertight seal in the box. The patent-pending wire clamp feature 
gives you the ability to also install aftermarket radio systems and 
maintain the watertight features of the receiver box.

Removing the Receiver

1.  To remove the cover, remove the three 2.5x10mm socket-head 

cap screws.

2.  To remove the receiver from the box, simply lift it out and set to 

the side. 

3.  Unplug the servo cables from the receiver and remove the 

receiver.

Receiver Installation

1.  Always install the wires into the receiver box before installing the 

receiver.

2.  Install the antenna wire and the servo 

cables into the receiver box.

3.  Arrange the wires neatly using the 

wire guides in the receiver box. The 
excess wire will be bundled inside the 
receiver box. Label which wire is for 
which channel.

4.  Apply a small bead of silicone grease  

(Traxxas part #1647) to the wire clamp.  

5.  Using double-sided adhesive foam 

tape, install the receiver into the box. 

Note: For best performance, it is recommended that the receiver 
be installed in the original orientation as shown.

6.  Plug the wires into the receiver. Refer to page 12 for the wiring 

diagram.

7.  Make sure the box light pipe is aligned 

with the receiver LED. Make sure the 
O-ring is properly seated into the 
groove in the receiver box so that the 
cover will not pinch it or damage it in 
any way. 

8.  Install the cover and tighten the three 2.5x10mm socket-head 

cap screws securely.

9.  Inspect the cover to make sure that the O-ring seal is not visible.
