Wye vs. Delta

I just read briefly over most of the posts in here (good stuff guys; understood a good deal of it, woooo!), and I may have missed it, but could it be perhaps Aveox (as was copied and posted by the OP) was referring to sensored motors?

The only way I've experienced a wye wound motor acting poorly is running my Novak in reverse direction (this is on a sensored ESC though; I've never tried it on my mamba or anything yet). Performance goes down hill big time. The timing in those motors is "built in" by the Hall sensors, so it's like running retarded timing when run backwards, no?

If they're referring to strictly sensorless wye and delta winds, then I have no idea what the hell they're talking about, and you should probably ignore my post.:D
