from what I have heard...yes. I'm no expert and have never been to the factory but the rumor is that the HW is an Orion knock off. They look exactly the same and comparing the two physically it would seem so. Not 100% on the hardware internally but others say that they are equal. They have the exact same interface on the lcd programming box just different stickers. I've heard great things about the Tekin combo as well. The customer service with Tekin is going to be highly superior to HW....but at $80 a pop if my ESC fry's then it will just be a replacement purchase instead of sending it back...but i've seen more Tekins melt than HW's so I'm hoping that won't be an issue...we shall see.
+1 to Tekins customer service, very hard to beat. Agreed 100% on even if you were to have an issue with HW, for the price it still a great buy.

lol, well i wouldnt say that a HW is a Orion knockoff since HW makes the Orion esc for Orion. I know they do differ a bit internally comparing the 2 but from what i have heard hobbywing makes it for Orion to there specs. I have have run both and cannot tell even a slightest difference.

Just got a text from a buddy and his HW Xerun just came in. Ordered it from..
http://www.rcecho.com/XERUN-Competit...-150A-ESC.html
Took less than 2 weeks to arrive and it looks like they have some left.

you can take a lower kv motor and gear it up, or a higher kv motor and gear it down to achieve similar results
Also, you can take a really low kv motor, and use 6S to achieve similar RPM to a higher kv motor on 4S.
2000kv @ 14.8v = 29600 RPM
1300kv @ 22.2v = 28860 RPM
What this can achieve is longer runtimes (and i THINK less heat, but can't remember) out of the same capacity battery.
(Yes, I know that isn't the WHOLE story, but it's the basics)
But again, most tracks want you to run 4S.
1800-2000kv seems to be the range you should be looking for. Works well for me on a 80x200ft track with fast straights, big jumps and a hard-packed often slightly grooved surface.

I tested -in order of appearence 
2200kv 4s castle
2050kv 4s tekin
1350kv 6s tekin
1400kv 6s tekin
4000kv 2s tekin
went back to 1400kv 6s tekin
1645kv 4s leopard -> sold it two weeks after
1400kv 5s tekin
stayed with this setup that I run on my two converted buggies (JQ and Durango)
For the guys wondering why I'm not running 6s with the 1400kv -> because tracks are smaller here and I'm faster and more consistent in 5s. A 1400kv 5S setup runs cooler and has a little more top end than a 1700kv in 4s. An other point is that I drive indoors too. My laptimer and my temp gauge decide what setup I drive

RX8/1900kv, real smooth and easily tuned with hotwire. Tekin support is also top notch, and how many other manufacturers take the time to go onto forums like RC Tech and oOple to help solve problems? For me that is a big plus.

The flip side to that, the lower the kv, the more torque the motor has.
