To speed up the repair process, please follow the
instructions listed below.

1. Under most circumstances return the ENTIRE system:
touring car and radio.The exception would be sending in
a Stress-Tech part. See the instructions under Stress­Tech Guarantee.

2. Make sure the transmitter is turned off, all batteries are
removed and fuel is drained from the tank.

3. Send written instructions which include: a list of all items
returned, a THOROUGH explanation of the problem, the
service needed and your phone number during the day.If
you expect the repair to be covered under warranty, be
sure to include a proof of date of purchase (your store
receipt or purchase invoice).

4. Also be sure to include your full return address.

All pictures, descriptions and specifications found in this
instruction manual are subject to change without notice.
DuraTrax maintains no responsibility for inadvertent errors
in this manual.

Do not use too much force when tightening self-tapping
screws into plastic. Overtightening will cause the threads in
the plastic to strip. We recommend that you stop turning a
self-tapping screw when you feel some resistance as the
head of the screw comes in contact with the plastic. Avoid
using powered screwdrivers when assembling this kit.They
tend to overtighten the screws. Do not use thread locking
compound on any self-tapping screws. The thread locking
compound may damage the plastic. IMPORTANT: Use
thread lock on any fastener that is threaded into metal or
fastened with a nut.Vibration from the engine will cause the
screws to loosen if thread locking compound is not used.

To operate the Street Force GP2 these items are required:

• Fuel (DuraTrax Red Aler t™fuel - DTXP0520)

• Air Filter Oil (DTXC2465)

• Glow plug wrench (DTXR1170)

• It is also helpful to have a couple of extra glow plugs

on hand (DuraTrax Carbon Speed DTXG3003)

The Nitro Starter Pack from DuraTrax (DTXP0200)
includes fuel, deluxe wrench, fuel bottle, rechargeable
glowplug starter and a glow plug.

For the Pre-Built version of the Street Force GP2,y ou will
also need:

• 2-Channel radio with two standard servos (FUTJ14**).

•

(12) “AA” batteries - four for the receiver and eight for
the transmitter.

• Small bottle of thread locking compound (DTXR2010).

To assemble the Pre-Built version (DTXC0052), you will

❏ 1. Install the air filter onto the carburetor. Using

the included tie-strap, secure the air filter to the carburetor.Cut
off any excess portion of the tie-strap to avoid interference.

❏ 2. Remove the twist-tie from around the receiver antenna

wire.Run the length of the antenna wire through your fingers
to help straighten the wire out.This will make it easier to get
the wire through the antenna tube. Slide the antenna wire
through the antenna tube. Press the antenna tube into the
antenna mount molded into the top of the radio plate.

❏ 3. Frequently, there will be leftover wire protruding from

the antenna tube. Do not cut or coil the antenna! Cut two
pieces of fuel tubing 1/8" long and slide them over the
outside of the antenna tube and wire.This is to help hold the
excess antenna onto the tube and avoid getting the antenna
wire cut in a roll over. Note the placement of the fuel tubing
on the antenna tube.

❏4. It may be necessary to loosen the radio plate to remove

the receiver battery holder.Install 4 "AA" batteries (included)
into the receiver battery holder in the configuration molded
into the battery holder. Install the receiver batter y back into
the receiver battery holder as shown.Make sure to re-tighten
the radio plate screws once the receiver battery is in place.

before operating your vehicle.Tur n on the transmitter using
the switch on the side. The red light on the side of the
transmitter should light up. If there is no light on, turn the
transmitter off and check to ensure that the batteries are
making contact with the metal contacts in the battery holder.
Make sure the batteries are installed correctly. Turn the
transmitter on and check for the red light. If the red light
appears, turn off the transmitter. If the red light blinks, the
batteries are low and should be replaced.

❏ 9. Raise the body posts to the upright position. Notice

there is a molded pin that fits into a hole in the shock tower.
This is to keep the body posts from swiveling during
running. Tighten the screws in the body posts, making sure
that the posts pull tight against the shock towers.You will
have to remove the screws in the tops of the front shocks to
get to the front body mount screws.

❏ 10. Apply the decals to the body.

❏ 11. Remove the body clips from the parts bag. On the

front body posts place a body clip in the bottom hole of each
post. On the rear body posts place a body clip in the third
hole from the bottom in each post. Place the body onto the
body mounts.On each body post place a body clip to secure
the body onto the chassis. The excess body post can be
trimmed off if desired.
