Upper deck and turret are easily
removed from the chassis. This allows for easy access
to the interior. Two bolts attach the turret system to
the deck, four screws attach the deck to the chassis.

Here is the turret waiting to be installed
onto the deck. The geared turret motor is attached
directly to the main board. Base of turret is then
bolted to the motor with a 12" ball bearing lazy susan
sandwiched in between.

Ammo feed is a simple tray sloped
from rear to front. The 90 degree copper elbow angles
down to feed the gun. Just below that is the elevate
assembly. This is the servo multiplier made by Servo
City. This is connected to 2 arms to allow easy
raising and lowering of the gun. To fire the gun is a
simple ball bearing servo. The giant open section
contains the 12oz CO2 with a macro line swivel
attached, no strain on the fittings. Rear hatch is
hinged and has a simple tongue and slot lock. This
allows for quick reloading during battle.

Two 4" fans provide direct cooling to the EV Warriors.
There is a vent above them
in the upper deck to allow cool air to be brought in
to the engine bay. The rear of the upper deck has
vents to release warmer air. Both vents use metal
gutter leaf guard material, sandwiched with plastic
window screening, to keep out debris.
Next are the relays which are mounted onto the
transmission supports. If you look closely at the
corners you will see the mounting bolts used for the
24 volt power feed.

Rest of the controller resides in the front of the
Comet. Here you see the second receiver and its power
supply. Not visible on the right side of the board are
the diodes for mixing the throttle and steering controls.

Battery compartment holds two 26AH 12v batteries. Top center
shows the mounting bolts for the 12 volt power leads
that control the relays, fans, and turret rotate
motor. The large white connectors can handle 50 amps and
support up to 6 gauge wire (or doubled-up 10 gauge).

Actual Comets had a canvas protective cover on the
gun mantle. I used some material scavenged from a
convertible top. Water repellent and paint repellent.
The bolt heads are part of the tensioning system.

Raised section directly behind the turret is the
air vent for the fans. At the rear you can see the
mesh area that allows for the warm air to exhaust.
The chassis and upper deck are built from 1/4"
luan, with fiberglass mat and cloth, which adds tremendous
strength with less weight. Paint is Krylon for
plastics; dries hard, fast and totally withstands
paintball goo.

May 2006:
The Comet's turret layout is much simpler than the previous version, showing
lots of lessons learned. A simple wooden try serves paintballs without
a problem (gravity is everywhere) and a $3 door lock actuator fires the
marker every time. A 12oz CO2 bottle provides lots of firing time and
a mechanical servo multiplier provides plenty of elevate power.
