600XF + Edge 120 Crazy Bogging

[kimthepilot]

Hi All,

I'm not really sure where to post this, as there are a lot of variables at work here...

Setup:
Trex 600 Pro
Skookum 540
CC Edge 120 HV
KDE 600XF530

Esc Settings are:
Current Limiting OFF
Motor Timing Low
I've tried a freq of both 8 and 12khz

I'm using the Skookum internal governor, using the Aux wire of the ESC as an RPM output.

Under hard collective punch-outs, sometimes it seems as though the motor shuts off completely, resulting in a mega-bog. While bogging I can hear a pretty loud chirping that sounds almost like too-high governor gain.

It doesn't do it all the time. Take a look at the image attached.



In the circle labelled 1:
SK540 asks for full power (Black line - Throttle Input)
ESC starts to ramp up power (Blue line) - Current increases as well (Green line) to match power output
Suddenly the power drops to around 60%, while the Throttle input remains pegged at 100%, power drops off, as does current.

Circle #2:
540 asks for full power
Esc gives full power properly (It actually reached 100%)

Thoughts? Things to try? Thanks for the help!
