legal car internals

[B3.is.King]

as i was thinking of poping along this summer with my son to race at heazel.

i was wondering would i have to get a BRCA membership before my first go racing or would i be able to try a couple of meetings with my son to see if he likes it before spending out?

also would we have to change our old brushed motors & lipo batteries to something from the BRCA legal lists? or is this not applicable to club level racing...
