I just got a Hobbywing XeRun 4168SL 2250kV motor this week and must say it is very nice! The overall machining and build is virtually flawless. The front endbell is held in via 4x hex screws and the rear endbell is captured via 3x hex screws. The motor wires are more flexible and the insulation is also softer and more pliable. Overall, a much better looking motor compared to the previous EZRun 1/8-motors. The motor wires also exit through a black rubber piece almost identical to those used on Neu-Castles. Comparing it to my Neu-Castle, it looks just as nice and many characteristics look very similar or identical. I wouldn't be surprised if Hobbywing contracted the same mfr that makes CC's Neu-Castle motors.
Supposedly these new XeRun motors are 4-pole. I never got a response from HW when I emailed them to confirm that. So far, the specs shown on chinese RC forums and chinese vendors all say 4-pole. I somewhat doubt that still, but am hopeful they really are 4-poles. I haven't had a chance to install it yet, but hope to soon to check out the performance.
Volume-wise, these are slightly larger than the Tekin and Neu-Castle motors since those are 40x68 and this is 41x68.
I'd really like to get my hands on their larger 4274SL 2000kV motor. It's 42mm with the machined-in fins, but I believe it's a 41mm case also.

Here's some pics...

looks nice, but i want to see the guts.

I run them in 1/10 scale also!!

So did you get the esc also? Where did you get it from? How much? I am in the market for a new system as I am waiting for the V2 SP system to come out. I just sold my MMM/2200, I am thinking MMpro Tekin motor. I want both my systems to be sensored, The v2 sp esc is supposed to be a SP rebaded 80 amp Xerun. Which is fine because I want to buy 1 now bit dont really want 2 of the same thing, and I dont want the xerun motor because its not sensored. I dont know the method to their madness on that 1.

I don't have the ESC. I got the motor in a trade. The person I traded with has the ESC though and he seems to like it. I'm pretty sure the SP ESC will be the XeRun 80A, so if you get that, it will be almost identical ESCs. I don't know what additional programming features SP will add...honestly, the standard XeRun programming features seem plentiful already.
The people I know that bought the new XeRun systems (both the 4168SL and 4274SL combos) all got them from either ebay (swanghobby, jns.inc, and a few others) or HK vendors (rcmart, etc.).
I run the XeRun motor with an EZRun ESC and it doesn't seem to cog at all (neither does my EZRun 60A ESC with a Medusa motor...virtually no cogging...and neither systems are sensored). My EZRun 150A with Neu-Castle 2200kV cogs quite a bit though, more than my liking. I had one owner of the 4274SL combo tell me he verified it was a 4-pole, but not sure how he did it.
As for the sensorless combos...that's just like CC. They don't offer a sensored motor, but still want to offer a combo should people want that, so they offer a sensored-capable ESC with their sensorless motor (just like MMPros with sensorless CC motors).
I was going to try to get some low-kV sensored buggy-size motors made for me that would've been lower cost than anything currently available, but there wasn't enough interest to meet the minimum order requirement. Currently, the only sensored 1/8 buggy-size motors with low enough kVs to run 5s and 6s on are from Tekin...I was hoping to find a lower cost one for myself and did, but there wasn't enough interest (too many people with big dollars willing to pay double for the Tekins and not enough looking for a lower cost option). So, I'm sticking with 4s setups for now. I might go to 6s later, but I'll wait till all my 4s packs die first as that's a big reinvestment in batteries.

I am in the same boat as you with wanting to go to 6S. But finding a 1400 Tekin used is never going to happen because everyone is going to 6s. you can get 6S packs cheap though so thats easy. I have a new 4S pack that I may sell and just go for it. The SP system I am pretty sure will be the 80 amp though so I want to hold off a bit or just like you stick with 4S for a while. I want 2 systems or at least 2 esc's to have 1 for a back up. I may get a MMpro with a 2050 or 1900 and the SP also when it hits. Their new motors look really awesome. I am going for the 9.5 2160KV. I do wish they offered lower than that but thats the lowest they offer.

If you can gather interest, I can have motors made. I was going to make a 1350-1400kV and a 1650-1700kV. I like having back ups too. I have backup motors for a couple of my smaller vehicles, but none for the 1/8 truggies. And I used up my backup ESC because I smashed my ESC in an impact.
Good luck with your search and whatever decision you make.

You cant get just me and you a 1350-1400 sensored motor? What do you think of the 8th scale SP v2 motors?

How do you think that motor and the 80 amp esc would hold up on a Losi 8 for racing on 4s lipo?Do you think the 150 amp esc and the 2000 kv motor would be a better choice?

malik

On 4s the 80-2250 is whats recommended the 2000kv motor is truggy sized. You can use which ever esc you want but for 4s the 80 will work the 150 is for up to 6s.

The 80A is plenty for a buggy, as is the 4168SL 2250kV motor. Really, the 4168SL isn't much smaller than the 4274SL...only 6mm shorter, that's it. It has plenty of torque to push a truggy around, especially the newer truggies which are lighter than the older generation ones. In a buggy, it will be fine. Many people just like to overdo it (they want the insurance of that extra headroom, though you pay for it). If the 150A is out of your price range, the 80A will work great.

Have you seen anyone racing a losi 8ight with the 80amp combo?So you say the 80amp is plenty for 1/8 scale buggies.Good to hear,you just can't beat the price really.

Malik - unless you want a LOT of spare motors, you and I alone are far from meeting the min order requirement. Get 30 interested people (in any kv combo) and I can move forward. The SP V2 motors look nice. The wire connection is unique but honestly I'm doubtful of its advantages to lower heat. The size looks to be the same as the V1s. The motors I can have made are the same size.

Sjawzie - there's a member here who races with the EZRun/Xerun ESCs in Singapore, both the 80& 150A and he seems to do very well.
