Scorpion 4035-500 settings...

[K2Freak]

Hi All,

Is there a website or any info for best practices regarding CC ESC settings for the scorpion motors? I am curious about PWM, timing, and the other motor specific settings.

Thanks, Scott

If your planning on using a Castle Creations ESC..DO NOT use outrunner mode.
CC does not recommend it for Scorpion motors.

Could you elaborate on the outrunner mode not recommanded by CC please ?
I am using it (with a CC ICE HV 160) on an Scorpion 4035-500kv motor and everything's fine...

There was a bit of a debate over this...Feel free to read through and decide for yourself

You will have to enter the gearing information and adjust the gov gain but for an example:

"Motor Timing: 5deg

Thanks.! That's exactly what I was looking for. Sounds like there really isn't much discussion regarding what to do for performance - it's about what the motor wants in order to run correctly and last a full life...
