Update: I found out that it was not on braking that it was going over current but on startup. I was trying to get the fastest start spin up to get the ship up to speed quicker on takeoff. I increased the start spool-up to custom 7 and the starting motor power to 80%. This was what gave the over current situation. I later made things worst by increasing this to spool-up at high - 8 and start power to 90% this caused a over current shut down. I remember having this happen on my Ringmaster setup so looked back at my notes and found that these two settings should be a medium for both. Reset and did ground test with no issues or ESC beeps.
I got out for a full test flight. All was set and the weather was holding (was supposed to be raining all weekend) so I figured I would see if I could get the fight in. Flight went as planned, motor start was smooth and solid the whole flight with a clean cut off. No ESC beeps or signals for over current.
Seems the good starting point for any of the Castle Creation ESC's is to set the start spool-up rate and motor start power to medium, current cut off can be set to normal with hard cutoff. This is what I call the Fox 35, 10x6 prop, 5%N Superfuel set up, it is reliable, simple and easy to set up.
