Today we're converting a standard 2WD Slash into a "Monster Slash".
With a simple brushless power upgrade and bigger wheels we can give
the model an aggressive look with improved performance. With our 2WD
Slash we will install a Velineon VXL-3s power system along with a 14-tooth
pinion gear to accommodate the bigger wheels--part number 2427. For optimal speed and run
time, a 2-cell or 3-cell Traxxas ID lipo battery is recommended. To make
setting the gear mesh easier, we will use the adapter from part number 3790.
However, this part is not necessary for setting the gear mesh. For tires, we will
use Talon tires with all-star black chrome wheels designed for the Stampede VXL.
These oversized wheels will give the model a lifted stance with a sleek
appearance. We will use 3668A for the rear and 3669A for the front. To
accommodate the larger wheels, we will also use the extensions in the body
mount kit--part number 1914R. Shock spacers can also help to get
the proper ride height when fitting the body over the wheels. Extra spacers are
generally included with the model, but they can also be found in the spacer kit--
part number 3769. Tools needed will include 1.5 mm, 2 mm, and
2.5 mm hex tools, as well as a wheel tool and a pair of pliers. We will
also use a pair of body scissors to trim the body in order to accommodate the
larger wheels and tires. Use caution and adult supervision when working with
these tools. First remove the wheels from the model.
With the wheels removed, we can go ahead and switch out the power system and
pinion gear. Remove the gear cover to access the motor. Loosen the two screws
that secure the motor. Remove the bottom screw but the one on top can stay in
place. Once the motor is free,
disconnect the motor from the speed control. If using the fixed gear mesh
adapter, we will use the A-B adapter with the lower motor screw in position B.
This will accommodate the 90-tooth spur gear and accessory 14-tooth pinion gear. Put the adapter
into the motor compartment and align it before securing the Velineon motor.
If installing the motor and gear without the adapter, see the related video for
more information on setting the gear mesh. Install the 14-tooth pinion gear and align it
with the spur gear. With the gears aligned and properly meshed, fully
tighten and secure the pinion gear and motor screws.
Now we'll replace the gear cover.
To remove the speed control, we will first open the receiver box. Disconnect
the speed control connector from the CH 2 slot in the receiver and
pull it out of the receiver box. Now remove the stock speed control from the
model and replace it with the VXL-3s unit. Put the new connector into the
receiver box and plug it into the CH 2 slot in the receiver.
Tuck in the wires and close up the receiver box.
See the related video for more information on ensuring a watertight
seal. Now thread the color-coded motor wires through the hole in the rear shock
tower and connect them to the speed control. With the electronics installed,
we can change out the body posts. Remove the stock front posts and install the
extended body posts from the 1914R body mount kit.
In the rear, simply remove the four small screws from the back of the body mount
and raise it to the uppermost position.
Now we can install the new Talon tires.
With the body on the truck, we can check the clearance and trim around the wheels as needed.
This is where the extra preload spacers can help to set the ride height. We will
add a couple of spacers in the rear to raise the height. Continue to check the
fit and trim a little bit at a time until the shocks can compress without
the wheels rubbing the body. When the fit is just right, it's time to take the
Monster Slash and kick up some dirt. With just a few simple upgrades and
modifications, you've got a whole new way to have fun with your Slash. Where would
you go to unleash the monster Slash? Let us know in the comments down below.
