HB is at it again, pushing the boundaries of R/C to the extreme with the introduction of the HB Underground Championship Series. The inaugural race kicked off last Sunday, December, 16th at Bending Corners Raceway in Orange, California. Drivers from all over the SoCal area came out to play under sunny skies for a chance at getting their piece of the $1600 in cash prizes.
There were two classes offered in an effort to separate the novices from the pros with the winner of each class taking home 400 big ones. The rules were simple. Entrants in the spec class were allowed to run the Cyclone S or Cyclone S RTR chassis with an HPI 27 turn motor, 1500MAH battery (provided by HB), and HB Gumballs tires. The chassis could not be modified or upgraded in any way beyond basic tuning. The Spec + class allowed for more freedom allowing any HB chassis, with any NIMH or NICD battery, any Roar approved 19t motor, and HB Gumballs tires. Both classes also required the use of an HB or HPI body shell.
