micro buggy, top end electrics help!

[catman79]

hi, last year I briefly flirted with micro racing, I had an lc racing emb, with hobbywing 60a sensorless speedo and motor. sadly I sold it..
I'm thinking of giving micro another shot and wondered what the top national guys are now running? ive noticed sensored stuff is now available. any help would be greatly appreciated, ideally id like to put together something that would be competitive at the very top level.

thanks in advance.
