typical stick type battery packs. If you are using side-by-side racing 
packs, simply flip the hold-down over to the 23mm side and use it on 
the opposite side of the chassis. Accessory hold downs and foam (part 
#3927X) are available to accommodate larger battery packs. See the 
3903 E-Maxx parts list for more information.

The Traxxas High Current Connector

Your model is equipped with the Traxxas  
High-Current Connector. Standard connectors 
restrict current flow and are not capable of 
delivering the power needed to maximize the 
output of the electronic speed control. The Traxxas connector’s gold-
plated terminals with a large contact surfaces ensure positive current 
flow with the least amount of resistance. Secure, long-lasting, and easy 
to grip, the Traxxas connector is engineered to extract all the power 
your battery has to give. 

RADIO SYSTEM RULES

• Always turn your TQi transmitter on first and off last. This procedure 

will help to prevent your model from receiving stray signals from 
another transmitter, or other source, and running out of control. Your 
model has electronic failsafes to prevent this type of malfunction, 
but the first, best defense against a runaway model is to always turn 
the transmitter on first, and off last.

• Always use new or freshly charged batteries for the radio system. 

Weak batteries will limit the radio signal between the receiver 
and the transmitter.

 Loss of the radio signal can cause you to lose 

control of your model.

When using 6-cell battery packs, install the supplied foam block 
(spacer) into the front of the battery compartment. The spacers are  
located in your instructions package. The spacers are shaped to 
conform to the chassis. There is a right and a left. Test fit them to 
confirm their location. Remove the backing from the self adhesive 
strips and secure them to the front of the battery compartments.

Remember, always turn the 
TQi transmitter on first and 
off last to avoid damage to 
your model. 

The following Traxxas High 
Current Connector packages 
are available from your 
hobby dealer. When using 
adapters, be careful not to 
exceed the current rating of 
the Molex connector.
