thanks guys
just to double check...
i wanna run 4s (my charger can do 5s but it's a chinese copy charger so i dont wanna push it (a good copy though)) so is 2200kv medusa (80mm) gonna be high enough kv's?
my friend had a revo conversion, he hwas running a feigao 9XL on only 3s and cooked it when he geared it up to get some decent speed out of it.
now i dont wanna have to gear up due to a motor with too little RPM's.
i have my rustler for uber speed so this revo has to be around 45-50mph speed wize.
heat is BAD and the last thing i wanna do is use fans (i have a CC bec but i don wanna load it up too much with all of the revo's break servo's etc)
so i wanna keep the heat down (happy to use non-fan assisted heatsinks) and the speed around 45-50mph on 4s.
i have access to a couple of 8k 3s packs so on the rare occasion i may hit the 6s but not for long.
i was gonna go with hte 2650 from castle but now i'm kinda leaning towards a 2200kv 80mm medusa, you guys either have to push me over to medusa or stop me leaning and push me to castle-neu motors.

thanks guys,
