Ahh me PWRX RC days.. these were very popular about 7 years ago.
I'm sure Adz still has the photos from our inaugural event at Hillary's car park
100km/h+ was a piece of piss at that car park, my full Works spec Kyosho V-One RR Evolution 1:10 nitro with Sirio Evo 2 motor and high speed gearing used to do it with ease!
