I ran a 13.5 1S blinky with motor timing at CWIC, as per BRCA rules. Although I won my heat, I qualified fifth in the A - a full two laps behind 21.5 2S BLINKY without timing. In the finals I was truly outpowered. 13.5 1S will be fine at Gloucester but allowing 17.5 or 21.5 timed is just silly.
BRCA all the way I'm afraid for me.
