Project Hybrid Theory is a project truck that
started off as a simple paint idea for a body which soon blossomed
into a much more complex idea. I first wanted to paint a
tribute body to the band Linkin Park which has some personal ties
to my wife and I as well as our best friend. From there is I
thought it be an awesome idea to put a more scale looking chassis
under the body. Thusly, Project Hybrid Theory was born.

Starting
off with a Tamiya Volkswagen Race-Touareg chassis is where our
project begins. It features a solid rear axle and
independent front suspension design that is true to Chevy
trucks. The suspension and width fit however the length was
way too short by about 3 inches so the rear half was cut off to
allow a custom rear chassis to be adapted.
The
front gear box is assembled per instructions with the only changes
at this point being the addition of ball bearings and an Integy
55T motor.
The
rear axle is assembled per instructions with once again the only
addition being ball bearings.
Here
is the completed front section ready to accept the new chassis.
Placing
the completed front section into the body allowed me to figure out
just how long the new chassis piece would need to be.
Aluminum
"L" channel from the local hardware store provided the
right base for the new chassis extension. Strong yet light,
it would also provide great torsional stiffness. Here you
can see it has been cut into left and right pieces and the holes
have been drilled.
Test
fitting the new sides shows that all the measurements were proper
and it is ready for cross braces and a floor pan.
A
section of fiberglass was cut to provide a floor pan and the
remaining aluminum channel was cut to provide cross braces.
Here you can see the holes being drilled to accept the screws that
will hold it all together.
The
chassis assembly is screwed to the Tamiya front portion. It
is a rather stiff assembly and should provide plenty of strength
once finished.
The
body is fitted once again to provide measurements as to just where
to mount the rear axle. Yokomo dish wheels makes it easier
to measure with the wheel arches. Marks are made on the
bottom of the chassis so that the suspension can be laid in.
Numerous
measurements were taken from the stock chassis and then applied to
the new chassis. After several checks to make sure it all
lined up properly, it was time to see if everything was measured
correctly.
A
trip to my drill press and a few minutes later the holes were
drilled. If they were off it was too late now.
The
suspension components are installed and finally the rear axle is a
part of the truck.
A
check with the body revealed that all of the measuring was done
correctly. The shape of the truck is finally taking
form. At this point the only thing left to do is to make the
new driveshaft and to install the shocks.
Here
you can the molded in fenders were cut to allow the room needed
for the 2.2" wheels and tires.
The
HPI wheels have been narrowed by taking the outer beads off of
both sides. The chrome plating is being stipped to allow to
tires to be glued to the inner area.
The
body has been mocked up to show what the truck will look like and
to make sure everything is measuring up correctly.
I
made a new skid plate to replace the stock plastic one that is in
the kit out of aluminum and attached the front bumper from a HPI
Hellfire. Here it is attached to the front of the
truck. I may go and etch in a design on the skid plate like
they do on many full size trucks.
Here
is a mockup with the body on and the new front bumper and skid
plate combo in place. The front of the body had to be
trimmed slightly to allow it to sit properly over the bumper.
A
set of Mini LST shocks from 3Racing were purchased because of
their size and the quality of the parts. They were rebuilt
with 40 weight oil and new rod ends to allow them to be mounted to
this truck. Rear trailing arms were constructed from 6-32
all thread and aluminum rod with Traxxas rod ends.
The
new trailing arms next to the stock units. The reason they
are being replaced is that they allow too much movement which
limits the shocks effectiveness.
HPI
Geolander tires were chosen instead of the Pro-Line rear buggy
Dirt Hawgs that were previously mounted. MSD rock rings were
installed to give them a tougher appearance. The machining
is of very high quality and are installed using 4-40 button head
screws.
The
rear trailing arms are installed and now its time to make shock
"hoops" so that the upper part of the shock has a place
to mount. Once again fiberglass is used.
Finally,
the truck is able to stand under its own weight.

I
quickly painted up the Chevy Silverado body in straight black and
slapped it on. Since it is scale I added some mirrors from a
HPI drift detail set.
You
can see I changed my mind on the tires and wheels. I'm using
the tires from the Tamiya F-350 kit and HPI wheels. Tire
size has changed from 2.2" to a more scale 1.9".
Don't worry though, the original wheels have been kept and will be
used in a future project truck.
Here
you can see the electronics are finally fully installed at this
point including a working winch.
The
body has been fully stickered and I have also built a custom light
mount. Nothing suited me commercially so I made one myself
out of styrene. Unfortunately I got so into building it I
forgot to take pictures of it during the process. You can
also see the new Integy aluminum wheels I picked up for the
truck. I think they really set it off.
Here
is a close up of the light mount.
After
spending an hour soldering the lights are finally mounted and put
to the test.
