I'm currently running a speed passion LPF speedo with a speed passion 6.5r motor in my b44.
it's reasonably rapid, but the xcelorin 6.5 combo is tempting me. I like the geek factor of being able to tweak the ESC with a laptop
like for like, is the 6.5 xcelorin combo any quicker (punch and top end)? as a reasonably quick club racer, will I notice a difference?
