The building is cavernous, with a pit area and a great track with some nice chicanes and hairpin turns.
It's a very popular place on a Saturday afternoon, with groups of people coming in to race each other and a series of birthday parties.
Of course I was interested in the electric nature of the cars and the charging systems. The karts have 20 HP DC motors and can go up to 60 mph. Here's the charger, it can handle one kart on each side.
It's a DC charger, using an Anderson connector with a large handle, dumping power right into the batteries. The pit crew was very skilled at guiding drivers into the pits, flipping the power switch, and plugging in the charger. When a new group of drivers is belted in, they pull the plug, flip the switch and guide them out onto the track.
I did the 3-session deal for I think $50, including helmet rental. Each session is 7 laps and I was pretty wiped from the G-forces. I placed 2nd and 3rd in my sessions, would have had 1st in the final session except for some douchebag that ran me up into the guardrail!
