I had a carbon frame chassis ordered from hong kong for the equivalent of 80 bux aussie but in the end it got sold out. The only other price i ever found was 270 from a new zealand hobby shop which was too much.
before i got the surikarn i got the following for my TB-01
Bearings through out the car
heavy duty one way diff
TB evolution 2 ring gears (plastic and lighter than steel)
one of the many get togethers at the local park and ride bus stations. the cars clear out after 8 pm and for some reason the security couldn't car less about a bunch of clowns running rc's be it sparky or gas. they get quite irate with the roller hockey people for some reason though.
