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 3x8mm button-head cap 
screws.
2.  To remove the receiver from the box, carefully pull it out (it is 
secured by double-sided adhesive foam tape) and set to the side. 
The antenna wire is still inside the clamp area and cannot be 
removed yet.
3.  Remove the wire clamp by removing the two 2.5x8mm cap 
screws.
4.  Unplug the servo cables from the receiver and remove the 
receiver.
Receiver Installation
1.  Always install the wires into the 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 bead of silicone grease 
(Traxxas part #1647) to the wire clamp.  
5.  Install the wire clamp and 
tighten the two 2.5x8mm cap 
screws securely.
6. 
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.
7.  Plug the wires into receiver. Refer to page 12 for the wiring 
diagram.
8.  Make sure the clear plastic light pipe in the receiver box is aligned 
above the LED on the receiver. 
9.  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.
10. Install the cover and tighten the three 3x8mm button-head cap 
screws securely.
11. Inspect the cover to make sure that the o-ring seal is not visible.
