including former champion Maniac
Kathy with it horizontal spinning bar;
the uber drumbot Grande Tambor
(Figure 7) which had a new and
better balanced drum for the
competition; Mr. Croup (Figure 8)
with its titanium armor and very
effective drum; and two Kitbots’ Weta
kits — Play'n Krazy (Figure 9) and this
year’s Motorama champion Mondo
Bizarro (Figure 10).
Also taking part were the
horizontal spinner Traumatizer (Figure
11); a modified BattleBots toy called
Bazinga; Kitbots Trilobite kit Thunder
Child (Figure 12); overhead spinner
Void (Figure 13); and drum spinner
This last bot is particularly
interesting as the drive is pivoted
along the longitudinal axis so it can
maintain contact with the ground
even when the rest of the bot
gyrodances when turning. This
improves mobility with the drum at
full speed. The weapon’s friction drive
is also unusual in that it uses o-rings
directly on the bell of the Outrunner
for powering the weapon.
Possibly the best fight in the first
round was Play'n Krazy versus
Traumatizer. Early hits by Play'n
disabled the drive on one side and
removed the screw that secured the
weapon axle on Traumatizer, which
then self-destructed when its own
blade hit its chassis.
The biggest surprise in the first
round was the defeat of the
Motorama champion (Mondo Bizarro)
— its first loss in 15 fights. It was
holding its own against The Rolling Pin
II — despite having lost drive on one
side — when its battery decided 15
fights was enough and failed.
In the next round of the Beetles,
the highlights were Maniac Kathy
knocking out Bazinga, and Grande
Tambor quickly defeating Play'n Krazy.
Grande Tambor’s new drum was so
well balanced as to be near silent, but
perhaps the hits did not seem as hard
as those of the old drum.
It turns out the kV of the motor
fitted to the new drum is lower than
what was in the previous version. It
will be replaced for the next event
