14/13-turn 24 awg Asymmetric

There's also more room in the stator than most of the older Blue Wonders. This makes some winds that were pretty much a strain into "no big deal." This is one I've been wanting to try because I always think if I had a little less power than the 13-turn I might manage slightly better efficiency.

So, yeah:

Tgy 2730 14/13T 24g dLRK Wye
Kv 1347 (16274/12.08v) Io = 0.49 Rm = 0.171

GWS 8040 HD Hex 620 3S
10294 rpm @ 10.55v/7.96a
Badcock: 541 grams 19.1 oz/thrust 83.1% Efficient
Drive Calc: 597 grams 21.0 oz/thrust 85.6% Efficient

GWS 8040 HD Rhino 750 3S
10861 rpm @ 11.39v/8.87a
Badcock: 606 grams 21.4 oz/thrust 81.6% Efficient
Drive Calc: 668 grams 23.6 oz/thrust 83.7% Efficient

I really like those numbers; they're right where I'd hoped. Still, I want to try another variant to see how it works. That's a tight wind, but not the end of the world.
