It's actually Chrome Nail Polish. I hand picked it from this huge bag of little bottles that my daughter's have collected.

Naw, I won't be doing my nails.

I prefer that "Manly" look.

Ahh, the "manly" look, when was the last time you took a shower? Dirty = manly! If that is true I am only manly when I come home from work!

That sucks man, all that time spent. I still haven't gotten a chance to finish mine up, only one phase left. Holidays has me slammed.

I decided to cap each end of the stator with a plastic disk much like the Croco site uses fiber. This does help eliminate the shorting problem by giving the wire something smooth to slide against.

Much time was spent trimming and cutting them out, but it paid off. No Shorts!

It's a 4130 AXI Stator. I wound it to a 4 turn Wye using 6 strands of 22 awg. It is tight too.

That's the crimp/solder termination that I talked about earlier. It works good.

I got the custom wound motor installed. Even though it's dark outside, I had to go try it. MUCH Better!

Much better low speed driveability. Cogging is almost non-existent. I can make it cog by grabbing WOT from a stand still, But even then alot of the time it will blast off with the front end in the air. It will do 4 wheel burnouts on the concrete drive.

Torque is MUCH better. Top Speed seems a little lower on 4S than the 4120 660kv. I'm thinking this will be a GREAT 6S setup. I ran it for about 10 minutes and the motor was cool to the touch. It's 37 degrees outside, but I don't think temps are going to be a problem. I also put thermal heat sink compound between the motor and the mount.

Now that I have cogging under control, I'll start bumping up the voltage until I get the speed I'm looking for.

@Johnrob - Is there any way to estimate the KV rating of an AXI 4130 4 turn wye wind? 6 strands of 22awg?

Good to hear that this custom wind works better. The kv must be lower, if the spped is slower, maybe 280kv? That would be a wild guess!

Estimate - Hard
Measure - Simple

Apply fixed (measure) voltage - measure RPM
Spin with fixed (measure) RPM - measure voltage
