another new hobbyking esc (150A)
 

this one is actually meant for cars:lol:

i think this is a remake of the ezrun 150a. for $70, it's a really nice looking budget esc. almost makes me regret buying that MMM. almost:wink:

also, the website says 6s, but the esc only says 4s. i think it is 6s because their 180a boat esc says 4s, but it actually rated for 6s

Yeah I saw that too, actually tempted to pick one up and throw it in the Savage Flux, see if I can kill it.

The ESC is hobbywin oem ver.
type one 80A 4S, and 150 6S.
hobbywin new ver esc same as old ez80-150.

maybe hobbyking put wrong photo?!

for a back up esc...may be worth a test.....good to have spare electronics in our hobby

Cool. Alright who's going to be the guinea pig?! :eyes:

Looks almost like a mmm clone to me.

I might be....we shall see.

so its a cheep clone of a failure prone esc...............yep thats going to work great!

It's not a Hobbywing ESC. Like I said before, there's a place that sells some sort of kit and whoever gets it decides what type of components to put on it.

Edit: I hope they got the sensor part of the ESC worked out though. The only reason why I didn't want to test it was the sensor problem and the fact it had similar specs as the Hobbywing.

Dam.... $70 I might have to try one out. :neutral:

*edit* I guess they changed the site to say 4s now.... Still would be a great 1/10 controller, maybe light 1/8.

Saw that on there as well, looks like that "anaconda" one that was posted up a couple days ago. I was thinking hw at first glance, but if you check out the instructions the programming menus are different and said uses the hk ss program card not the hobbywing. I had some of those "kit" ones like lutach was talking about. They worked, but not the smoothest, and were very touchy. I'd want to hear some feedback on this one first.

I was going to order one, had it in the cart and ready to check out, but then I couldn't find the programming card (HKSS program card). I assume this is the programming card for HobbyKing's SS line of ESC's but I can't find it anywhere. Once I find the right program card I'll buy it, but otherwise the manual doesn't give any info on programming with a TX. Live customer suport was no help, said they didn't deal with technical questions.

If it's only the 4S version, then it should be the 80A unit and not the 150A. The 150A is 6S and I heard they were having trouble with it. I wonder why they opted to go with the 3 capacitor version instead of the 4 capacitor version.

This is not made by HobbyWing, it's by xxx(Lutach, shall I hide their name?:yipi:) located also in Shenzhen. And yes, the sensor port works, actually it works better in sensored mode, with smoother start up. I tried it at 6S and it survived.

PS: Glad they changed the 4 small 220uF capacitors on prototype revision to 3 bigger ones.

I guess they're trying to minimize failures by underrating them. (?)

I would like to actually find the source that makes them. There are a couple places I think makes it, but not sure. Every ESC I've seen looks a bit different. I would love to get something special done, but can't really trust the places I know in Asia, but the ones I know, I can always have them change a few settings here and there.

I used to have a bl-esc with a basic car program from a manufacturer in shenzhen, together with a comfy black programming-box (but the linear bec grilled the esc on 5s). just can't remember their name, last time I visited their HP they had some new esc's, and I think they're the manufacturer of those http://www.hobbyking.com/hobbycity/s...pgrade_version)

anyways, when searching on alibaba, you find the manufacturer of the above ezrun-clone.

I really apprecciate the increasing choice of bl car esc's.

(edit: wrong link)

6S...bah... For $50 I'd rather get the MMM unit I know to work great and be well supported rather some chinese knockoff mystery esc.

I want to see some options for some HV apps. I want to see a 120a/12S+ esc. CC doesn't have any interest in making them for cars anytime soon, and any other options are limited.

They should know there's a lot of interest in such ESC. Patrick did say a HV ICE (160A) and maybe a 200A 8S ICE for cars will be coming soon.

Patrick=Scorpion?

Patrick = Castle Creations

Correct. Patrick is not a scorpion. :na:

sorry, I'm bad in names, I've ment "george", I think he's the guy from scorpion systems. Didn't they have plans for a car esc?

At least they have a 50v 12s 130a esc for about 260 usd, might be interresting for 1/5 conversions.

Yes, I have the 6S version of it. It needs a bit of more work and I really don't know when he'll do them. I haven't heard from him if and when he'll do a HV version for the car market.

Here is the thread:

I was going to guinea pig this one for my revo 3.3 conversion, there was 11 of em left and I was about to click pay now until I found a used MMM for $110. Money is tight and I would rather go with something that *has* a chance of surviving instead of a brand new esc that no one has any clue about. I will probably get one sooner or later though.

They are sold out now... Anyone get one?

Problem will be support. I have great support with hobbywing.

Any updates on this? Need a budget ESC for 4S 1/8 buggy application on Tekin 1900 motor(or lower, sensored use) or Medusa 36-60 1800kV or Castle 1512 1800kV.

Or anyone got a spare MMM? :intello:

you can go with this one:

+1 !!

I'm going to be buying one of these soon to run in my E-Revo as I want to move my XeRun 150A to my CR conversion I am doing, so if no one else has one by then I'll try and write up a little report on what I think of it.

I hv been racing the ezrun 150 n xerun 150 with 4274 n 4168 motors with great success.

hi folks,

as I have some problems with my xcelorin, I have tested the HK 150a today. It's my backup esc, but I will run it permanently, the xcelorin gives me headaches.

It says tht its only up to 4s, but I have read about 6s use. So I thought, well, let's have a try on 5s.

http://i52.tinypic.com/291kfhw.jpg

the bottom of the power board; the heatsink didn't get off. I am curious about the FET's.

the brain in the "ground floor":
http://i53.tinypic.com/2dtriwz.jpg

the Caps are 25v, so I will be save with 5s I think. Finally a ESC with sufficient power caps, 3x 1000uf.

http://i55.tinypic.com/oqygsg.jpg

Today I had a first short test run. Good throttle, little - no cogging. Default is forward w/reverse, after breaking it gets to reverse instandly. so I will remove reverse.

Power output is great, I think better then the losi. It's bloody big, but fits into my truggy. Programming with the box is easy.

As I am not sure about the BEC, I run it with the hextronic ubec (pretty good thing).

cool stuff, I will report some more next weekend :-)

IIRC, the 4833N FET is the same one used in the Tekin RX8 ESC. How many are there on the ESC?

You can run 5s with 25v caps, but it doesn't give you too much wiggle room for braking, especially when installing a fresh 5s pack, which is 21v.

all what you can see on the pic, afaik only on the bottom side? I could not get the heat sink off. dunno whats under the heatsink, but probably the same amount of fets. what would that mean?

Well, there are 36 FETs on the visible side which is pretty typical for a ~150A rated ESC. If there were the same number under the heatsink, that would be 72 FETs, and would probably be rated closer to 250A if not more. So, I would guess the heatsink is simply attached to the PCB and draws heat from the visible FETs via the circuit board. Might seem like a waste, but having the heatsink not attached directly to the FETs makes it more durable IMO (any shock on the sink doesn't affect the FETs as much), and would negate any chance of the heatsink not sitting flush on all the FETs (each one may not be soldered exactly flat).

From what I've seen of these HW ESCs, they seem pretty decent. It's just too bad their programming is limited and the software isn't the best IMO (poor slow speed performance). Programming-wise, they remind me of old-school Quark ESCs without the smooth low speed action.

I will say the FET arrangement/layout looks a bit odd. It's like they just plunked them down wherever there was room. Typically, they are arranged in specific banks/rows to make circuit paths as short and clean as possible to reduce copper losses. But whatever, I'm not an ESC designer...

Thanks for the information. A colleague just told me that there are no FET under the heatsink.

It's big, yep, but I think it's cheaper to manufacure like that. And maybe heat can dissipate better. As long as it fits onto the chassis, I don't care.

Programming options are plenty, at least enough for me, more then the Xcelorin has. And acceleration is good, too, depending on the setting. Tried a medium acceleration, compared to default "very high" weak and slow performance, felt very strange.

Throttle response was pretty good, no complaints here so far.

A strange question....
I have the same ESC and I noticed it uses an Atmel MCU.These days I'm trying to make an ESC(for myself) and I need source code which supports all funtions of this ESC.Does anyone has the source code or knows from where can I request it?

I highly doubt you will find the source code for any ESC since that is the heart of the whole thing. The hardware is relatively easy to do, it's the code that makes or breaks the product. If you legally find the code from a reputable source, I would be very surprised.

Me too....That's why I asked.

Are you sure?
see photos. tekin rx8 use 4108
