Just a little update on the 600XL - I ran it for about 5 minutes the other day in my XT8 with Truerc 4S 6400 and a MM and it was cogging on start up. If I was real slow on the throttle it wasn't too bad and once it was going it had all kinds of power. So this morning I eliminated the bullet connectors on the motor and just wired them directly to the MM motor wires. I also changed the starting power from low to high to see what would happen. I put it down and - cog,cog - magical smoke.

This is my only esc. so I guess I will be down for a little while until Castle can get it repaired. The motor seems to make a lot of power, but the MM just can't handle it. I think I am just going to buy a Feigao 9XL for now until Castle or Tekin bring out there new controllers.
