Y- vs. D-wound! What's the story?

[JoFreak]

Hi guys,
got a Stampede 4x4 recently and I'm looking into getting a nice motor for it.
Sort of settled on a Neu 1415 with 2000-2200ish kV.
That leaves the 2D and the 1Y.
This motor will run on a MMP and 4S lipo.

So are there any advantages/disadvantages to one of the winding types I may take into consideration since both options are absolutely equal to me?
I do know how the different kinds of windings work, and how the currency flows.
I just can't get behind what different effects that might have.

BL Motors are either Wye or Delta wound. Wye wound motors generate 1.73 times more torque than their Delta equivalent, but are also 1.73 times slower (1515 1 y = 2200kv, 1515 1 d = 4100kv).

Wye motors respond well to increased timing, Delta motors do not; in either case the current draw will increase & so will the effective kv rating. This thread is relevant:

Well now I'm even less sure which one to take.
Originally I would have leaned towards the 2D because it has a little less kV.
But now that I've read the thread you linked where Bernie said that D-wounds have no place in ground vehicles...

Please someone just tell me which motor of those two to get.
I'm not really interested in using the motor with timing.
I don't want a gazillion miles per hour top speed.
I want torque for wheelies and control in the air for back and/to front flips.
So quick spool up would probably be interesting as well.
Apart from that the motor shouldn't run hot, but that shouldn't be a problem for a Neu 1415 in a 1:10th scale 4wd monster, should it?
I would most likely run it at the lowest possible gearing of 12/54.
12T seems to be the smallest possible for 5mm shaft.

So, mighty RCM crowd, what's your verdict?

Bernie has his opinion, but so do I.

I've been running D wind motors for a while now and have yet to blow up a Castle esc or Tekin. Just yesterday I ran a D wind motor in the RCM CRT.5 with a Castle esc with zero issues. I also ran the Delta motor with 5 degrees of timing instead of the usual 0 degrees of timing, as I was swapping motors during the day.

If Torque is what you seek, then get the Delta.
Quick spool up is with 2 pole motors only.

Get the KV you need... I run several different D winds with no problems (0 and 5 deg. timing)

[suicideneil]

I'm inclined to agree- any 4 pole motor will have more than enough torque, just get tyhe kv rating which best suits your needs ( regards gearing + voltage = topspeed desired ).

2 pole motors do spool up faster than 4 pole motors, though I can't imagine you'll notice much difference in an MT that you aren't drag racing..

I agree with snell; I've run several Delta-wound motors with success. Actually, I still have a Neu 1512/2D running with an old Quark 125B (which is basically a Gen1 Mamba Max internally) geared for ~40mph, and it still runs fine.

Whatever motor has the KV closest to your needs, if that happens to be a D wind just don't time it past 10 degrees.
