HobbyWing EZRun 80A Review

The controller itself, while being quite large, functions rather impressively for the price. I haven't got a whole lot of time on it yet(it is winter after all), but my initial impression is quite favorable. I was actually quite happily impressed with its smoothness(testing in a 3905 emaxx with a 7xl motor) - as smooth as any other esc from my initial testing, actually.

Thanks for the detailed and specific write-up, Brian. You da man! :)

Good to hear your input on the esc Mike...will you offer the program card for sale?

Nice to have a cheap, no mod option for 4s useage... I may have to get one for my emaxx.

Also wondering, does it have a sensor port? The description lists it as useable with sensored motors...

To Brian and Mike, will either of you be testing this esc with 4 or 6 pole motors? Just wondering how it will handle a neu or plett... 75 dollar esc on a 300 dollar motor

Really nice review, thanks Brian!

I'll also buy this ESC for my Slash if the 60A Version i have is stressed too much with a Feigao 8L on 3s Lipo. It would be also perfect for my Truggy project if it works properly with 5s Lipo.

the 150 whit a 4 pole motor run whit no cog,so the 80 will do the samething!

[BL_RV0]

In theory that is true, but theory doesn't always works out...

[killermmn]

my firend have test the 150amp whit neu motor and no prob at all

150amp whit neu 1500kv and 6 cell lipo!!!

The best thing is run 4s without mode just for $75
Ther bad thing is just 80A so its not good with medusa 70's and 80's motors or neu 1515 motors that needs 100-120A
Thanks for the review

I am not so sure this is actually true. I am testing with a 7xl motor - which will draw as much or more current as a similar Kv Neu or Medusa. It is well heat sinked and seemingly conservatively rated - I suspect it will do everything the Mamba max esc did without the need to add a fan or external BEC (so about 1/2 the price). The downfall is the size - it is a behemoth!

Good to know. It does seem a bit larger, but that should only pose issues if you plan to run it in a buugy. Most mts and truggies have enough room. I do wonder if it will hadle the load of heavier tires and tall gearing, as i always felt the MM was a bit marginal at that, in the southern summer that is...

If it can handle a 7xl, that is pretty good. That motor is an amp hog, especially after it warms up.

I won't know how it handles the summer heat until, well...summer. :) The 3905 emaxx is not a light truck and has fairly heavy tires on it already(mine is stock and used for bashing around in the snow, etc. mostly). I am pretty sure it is over 11 pounds with the batteries. My guess is that the motor will be the weakest link in the summer - just speculation of course. :)

I will be testing it in my buggy using 4s and 1512/2d. And with the way I have it geared (46/15), that motor should pull close to as much current as a Med70 or Med80.

Late last night, I removed the Quark and ESC mount from the buggy and test-fitted the ESC. It fits, but barely. If the chassis has any flex, the battery tray will touch the ESC PCB - that's how close it is. I've been wanting to change things anyway, so sometime soon I'll be getting a new motor mount and a single battery tray. And I'll be getting a new 4s lipo pack. Dual 2s2s 8Ah MA packs are simply too heavy.

Nice to see this, I may have a plan for one of these in the not so distant future. I have been wanting a decent 4s ESC with a budget price, thanks Mike!

Thanks for the info guys... I will be watching this little esc closely. Not that I need any more escs. But it is nice to have options.

Could always go to an indoor ymca gym, setup a few ramps and stuff and ask the clerk at the counter to crank the heat to 90 degrees.

If it will handle a 7XL motor than it should work out well for most MT's. I smoked my mtroniks truck esc on a 7xl geared 20/68 which is what everyone with an MM was running. That ESC was only meant for 80A also. This sounds like a good low cost alternative to the MMM if you are only going to run 4S and it works in an MT.

[BrianG]

I'm really hoping it is stable on 5s. 80A @ 5s would be perfect for the majority of 1/8 b/truggies and 1/10 MTs.
