an esc for my revo

I've a e-revo, with Neu 1515, 1Y, MGM 16018 and a 4s, flightpower 5000mAh, and it's verrrrrrrrrrrrrrrrrrrrry powerfull setup, you can believe me
But if i spend some more money next summer i'll buy a 5s or 6s, just for the fun.
On my revo, i'am to remove the entire transmission. I'll only keep the output shaft and make an adaptor to mount a Kyosho 46 spur gear directly on the stock revo output tranny shaft. And i'll use the Tekno rc elektri clutch system to the place of the standart mod1 pinion to allow a little slipping from a dead stop.
