I don't want to get into the debate of which motor is better, but we just ran on the track today, an endurance run to see if we would get the motor to thermal. The 3674 ran on the track for 1 hour exactly. Went through 2 sets of 4S batts in parallel and a little into the 3rd set. Motor never made it over 145 deg the entire hour after the 2nd and last pit for battery swap. That was around ~70 laps. Guess their motors are another valid motor people should now consider.....I am impressed. After running it, we GPS'd. 39.6mph on 62/22 gearing and 5.25" tall tires off the XTM XLB buggy.

Great review jzemaxx I have been following this thread waiting for somekind of confirmation that these HW motors/ESC are a good alternative.I bought sometime back a Bidproduct Motor and looking at the motor you would swear it was a quality motor.I tried this BP motor and after 20 minutes the motor just stopped.It was a 2600kv motor on 3s with a MMMv3.It ended up cracking the stator/magnet. Since then I stayed away from these types of motors.I found the Hobbywing motor seperately here for sale http://hobbiesbp.com

Wow, nice prices on that stuff. Wonder how reliable that store is though. This setup has really impressed me.....

HW 2350 failure at 6s:

Were the temps at 145 taken with the dual fan combo? Does anyone has a link to see the motor with the fans? My 7xl with dual 40mm fans and a novak heatsink can run 42mph continously as long as the fans keep running.

Another thing to consider is that just because the outside of the can is cool (with fans blowing on it) it doesn't mean that the inside is cool.

I'm glad that the ESC is holding up though, I might have to get it over the MMM when RC-Monster starts stocking them. I'm also interesting in the advanced programming card.

The ESC is awesome...programming card is definitely a must.

Just curious, how are the temps with the fan removed? I found the 80A to get pretty hot even with cool ambients. Of course, it was running a higher kv motor (Neu 1512/2d, kv=2650 on 4s) in a Hyper 8. I expect the 150A version to do better, but curious how much better.

jzemaxx - thanks for the review. I didn't mean that their motors sucked, but for performance, the 4-pole would seem to dominate. How do the HW 2350kV and CC/Neu 2200kV compare on acceleration and torque?

BrianG - Has any testing been done on the MMM w/o the fan to see how well it works without forced cooling? Just making sure that there's apples to apples comparisons when we're critiquing the HW EZRuns vs. the MMM.

p.s. I'm curious about that hobbiesbp place too. Their prices are really good!

I didn't get any temp readings, but just by hand, the MMM was much cooler with no fan. But that was on a Mugen MBX5 (CORR conversion) on 5s with a Neu 1512/2.5d. So, no, no real apple to apples comparison.

However, before I installed the HW80A, I was running this same buggy and battery setup on a Quark 125B. Those ESCs are known for running warm, and the Quark was cooler while running longer in summertime.

Hmm, not apples to apples, but good info to have. Thanks Brian!
I wonder if the EZRun runs hotter or if it happens to be better at conducting the heat to the heatsink. Either way, the 150A is really a much more fair comparison against the MMM. The 80A is like a MM with some MMM-DNA injected...sort of in the middle between the MM and MMM.

BTW, can you comment on how the FETs in the 80A seem to come out with higher current capability than those in the 150A? 62A x 3 = 186A vs. 26A x 6 = 154A. Seems strange unless I'm looking at it wrong.

Red a thread on a german forum about the EZrun150A combo. 2 guys experienced shattered rotors after few runs. Esc seems to be promising.

well that motor (3674) is only rated for 4s, so wat did guy the expect that motor isnt designed to run at 52000+ rpm.the only hobbywing motor rated for 6s is the larger 4465,2000kv which i plan to run in my upcoming 12-13lbs. lst2 coversion on 5s, maybe 6s but it'll probably wont be able to handle that speed.

That's a good point, I didn't realize it was only rated for 4S.

The cheapest 4465 combo I see on e-bay is $234. That's not bad, but for that price I'd sooner get:
-HW 150A: $118 (eBay). I'd much rather buy this from Mike, so I'll wait for him to stock them.
-Medusa 70mm: $124 (RC-Monster). Or $140 for CC/Neu or Medusa 80mm.

Total: $242. And I'd add in the Advanced programming card when RC-Monster gets them in. For a $10 difference I have to hear a LOT of good things about the HW motor to select it over the Medusa.

I'll be honest with you...on accel and torque you can't tell the difference. Both will stand the E-revo straight on the wing. The HW3674 though just has more speed....6mph which is alot on a track. I figure the same setup is probably another .5-1 sec faster a lap, which is alot.
