For those you wish to use their existing Castle Creations ESC with a KR Governor I am listing two program code settings that work very well. These settings were developed by Cleon Lingwood and Brian Eather and are used with their permission.
I would like to thank Cleon and Brian for their kindness in and willingness to share this data. The only thing I would add to their fine work is to change the Endoints to Automatic (if you wish the motor to spin the prop a couple of times then wait at startup).
