The turret is easily removable by removing just one nut.

The turret of the White Night is its own R/C model. That is, it's
equiped with its own power supply and control system separate from the
hull. The battery pack supplies the 12 volts needed to operate the
trigger actuator and the bread-boarded electronics provides the 5 volts
for the Rx and elevate servo.
Note a new feature to a Tyng tank, a 24 volt battery charge meter from a
The motor bay. The EV Warrior motors are mounted to typical Tyng
transmissions (separate left and right, wedge tensioned linked belt
first reduction, chain reduction direct to drive wheels). Note the
easily replaceable plywood pulleys. If the need should arise for higher
speeds in the future. It would be a simple matter to install smaller
pulleys and adjust the belts accordingly to produce a smaller reduction
ratio. The current reduction is 9 to 1.
The dusty condition is the result of the frantic development pace in the
last week before Monkton. There was no time to build a proper intake

The battery bay. Some may have noticed that the wiring is not the same
as previously published reports (no busbar distribution system). A week
before the 1st Monkton Crusade it was decided to switch to a commercial
Robot Solutions (model RS80D).
This required a
redesign of the power grid. Six gauge wiring was used throughout and
the 60amp ANL safety fuse can be seen on the lower right.
This photo also gives a nice view of the turret rotate system. The
120rpm 24 volt gearmotor can spin the turret at roughly 1.2 seconds per
revolution, or 50rpm.
Dubbed the "White Knight" because of it's distinctive light gray paintjob
it sported at the 1st Monkton Crusade. T040 in this photo clearly
demonstrates two of it's advanced features while traversing over a
pile of bricks. It's Christie style suspension and sprocket drive TTS.
