Just stock K3 to race I have about 2100.00 with servos, radio, and engine. If I add the other engines/pipes, fioroni stuff, start box, tools and extra parts/tires to be set to race I would say about 7000.00 give or take some.
My woman doesn't care about my "net addiction" as she calls it, but not my wife yet. I'm sure she's spied on me, on many forums I've talked on in the past.
