Here's the setting I used with my Sphere Comp with a 13.5;
Mode 1: Value 2
Mode 2: Value 6
Mode 3: Value 1 or 2
Mode 4: Value 0
It is very important to have Mode 1 set to value 2 if you are using 4 cell NiMh's. Otherwise you could experience a shutdown because the ESC will see a low voltage condition, assume you are runinng LiPo's and shutdown. At least this "was" an issue with the early LRP Sphere COMP's.
The rest of the settings; Mode's 2 - 4 are drivability settings.
The non-COMP version does not have all of these settings, but I believe it does have some setting like the Mode 1.
