I know with some speed controllers, a higher timing is recommended with 4 pole motors. Hacker suggest 0-5 degrees for their 2 pole motors, with 2 degrees @ 8Khz being the most efficient for their motors. Hacker suggest 8 degrees for 4 pole motors. I run 10-15 degrees on my Y motors. On the D wound motor that I had, I just ran 0 Degrees. On Luciano ESC's I use 16Khz switching frequency for the 4 polers. Quark is set at 38Khz. What is the Castle PWM set at?

So, over the weekend I used 0 degrees timing with a 1512 2y and MMpro with 6s A123 in my Rustler. I then used 15 degrees timing and saw a difference in topend. I can pull wheelies while breaking the tires loose on concrete. I use heavy beadlocks btw. The fan did not come on and the system just ran "cold".

I remember Castle saying something about their ESC being able to automatically adjust timing for their motors, but not exceed the user "set" Timing setting. But I can be wrong with my thinking that though.
