We finally got a break in the rain, and even though those nasty puddles are scattered around, I had to try this custom wind.

I have ran the factory 5 turn Delta wind on the 3530 in the E maxx before. It performs well. I ran it alot, so I'm really familiar with it's performance.

Today, I found out how the 3 turn Wye wind performs. It runs cooler than the Delta wind. I know the math says that the KV is supposed to be slightly lower, but top speed and acceleration are much better.

This motor makes MORE power! It also starts better.

I can easily take off in 1st gear OR 2nd gear. I can grab WOT from a standstill in 1st anytime and it responds perfectly.

When starting in 2nd gear, it still doesn't like the 1st or 2nd step in the throttle, but anything beyond that is just fine. I can grab WOT starting in 2nd gear! It blasts out of the hole with great control about 90% of the time. The other 10%, it kinda screams at me like Metalman described his was doing.

My conclusion is, several things add to the improved performance.

1. Lower internal winding resistence. Any wind irregardless of number of turns or termination will perform better, the lower the resistence is. I have a feeling this makes it draw more amps, but also produces more Watts of total power!

2. I believe the Wye wind is MUCH better for this type of application. It starts under a load better. I also believe it is more efficient, hence cooler running.

I did the test run on 15C 4000mah 4S configuration. I ran it hard and it lasted 25 minutes. This motor performs like the factory wind on 5S Lipo, but does it on 4S and starts better.

I will now proceed with the AXI 4130 rewind. I found a different brand 4130 6 turn Delta that's rated at 515kv. I'm thinking about 3 or 4 turn Wye termination should be just about right.

More on that as soon as my winding wire gets here. I believe the mail is pretty congested in some areas right now because of the holidays.
