Manage to contact hobbywing china, seems that the person on charge Jack was very keen to know more abt the problems of the 150esc n will send one to me within 1wk:). Hope this time the esc will be better n who know I will race for hobbywing in Singapore :)

I fried my engine that's included in the 150A combo set. Sent about 5 mails to hobbywing but I didn't get a reaction. Do you have a mail address for me. I sent the mails to support@hobbywing.com and michael_shoky@hotmail.com wich I both found on the hobbywing website. The motor fried in 5 minutes. I'm now using a 36-50 robbo motor that is working fine.

His email is zj@hobbywing.com let me know wat he says. Good luck

thanks, just sent the mail again. I hope they will reply.

Managed to get a latest version of hobbywing 150 esc tested in my 3rd race.

1st heat software problem car has max drag brake, managed to reset.

2nd heat batt died, I used a 4s 5000 zippy set 4s manually on d esc but still one cell died. Dunno izzit batt problem or esc

3rd heat completed with no problem

At the Main batt pop out becoz it was a 6s n was not secured properly, fix n tried to run then found out d switch was cut by my spur gear. Tried to connect the black n red wire but can't start d esc. Din want to try d white wire in case the esc gets burnt.

So far I m ok with d esc change all setting except punch, esc ran cool. Need to find out how to undo the drag brake though.

Did you play around with the timing? how did you get the lastest firmware version?

my timing was set 11. Software I never update I din get d advance program card.

mine 150a ezrun esc is running great so far on my e-revo.
i have tried with 4s and 6s with a feigao 9 xl on track and lately i tried a sensored novak hv 5.5. and runs great too.
in my opinion beat the mamba monster because is much more easy to use and program.

that's good to hear, I m currently running wo a switch, my spur rip d switch off. Just be careful with the temp of feigao motors recomended not over 80degrees

my feigao it runs a litlle hot but nothing too hot until now.
the esc runs cool all the time.
here in portugal i have 4 friends with e-revos and all with these esc´s(thank´s to mee!!) and until now none brun or broke and two are 80 amp version.

so for the great price they are real good.

regards

the service is good too. I fried the motor during the first test run. It was kinda hard to contact them, but with help from superek4 I managed to get a hold on Jack. After showing the pic of the magnet and telling the story they offered a new motor for free. I only have to pay for the shipping which imo is very reasonable.
So great service!

that's good to hear, I m waiting for my new esc too

Mine 150A just died today.Lasted 3 weeks.
First motor stopped ...then go ....then stop again...loaded a fresh lipo pack...then puffff.... lots of smoke comming from the esc.
Thats great,at first 80A smoked then 150A smoked also.
This was powered by 4S lipo and recently I've loaded latest firmware from HW.
They should rename their escs to Hobbywing Fireworks


I believe I will pay a little more and get a Tekin.

What was the last setting like? Did u change the punch to zero?

mine stop working 2 days ago.
when i put the switch on the fan doesn´t work and the light on the esc shine solid red...
after a few tests with the esc case open i descover that th internal bec don´t work.
i will upgrade it for a better one and when i test the esc again i will post if is full working again.

regards

if it's not working take a pix n send it to hobbywing they will send u a new one. I just got mine with free heatsink n fan:)

thank´s for the tip but i have a race next week and i need the esc, i will try to fix it my self with my litlle experience.
can this esc work with 4 pole motors like neu or medusas?
i am looking for a new motor for my e-revo but want a eficient and cooler motor....

Yes, I m using a medusa in fact it's better just remember not to set d punch to zero, no drag brakes n put a fan on the motor.

my batteries are not much strong on discharge capabilities and i really like the novak hv 5.5 sensored i´ve run on track...
now i am on a indecision in what motor to choose....
i still continue with novak, feigao or medusa in my mind....
but for 4 s and weak batteries and longer run times on track what you advise?

regards

I burnt 2 feigao they r cheap but 2 poles can't last in high temp. Medusa is a better n cheaper option compared to Neu. I race with my medusa n they hv lasted n r good in customer service.

I run 10mins heats n 30min mains no problem with my 4s 5000 zippy. How long r ur race n wat car r u using?

i run between 10 and 30 min too... do you notice better run times with the medusa then the feigao?
what medusa should i use in a e-revo?
i was thinking the 36-60- 2000 or 2200kv one... os good choice?

Run time will depend on the amp draw of the motor, weight, gearing n batt capacity. medusa runs cooler n last longer as the magnets n bearings are much better.

I will suggest 70mm rather than 60mm as it's stronger n able to run d truck with less effort. What batts are u running for ur race? That will determine wat motor u shld use.

I used to run 2000kv in heats then main change to 1600 but I found it too tiring. So I use 1600 now throughout n change gearing.

Heats I use 16Pinion with 4s 5000 n main I use 11pinion on 6s 5000 with 1 batt change

ERevo has 2 batt it will b slower to change batt so in main u must use high capacity batt n lower d gearing so the esc n motor will run cooler unless it's winter in your county.

Make sure ur packs are of the same age as in series d older/weaker pack will discharge faster leaving it overdischarge.

Wat batts u hv now n gearing? Is this ur first race?

I m very happy with hobbywing after sales service, I was attended by a engineer named Jack. Not only he replied to all my emails for my damaged esc, switch n motor.

I got them all bnew wo any freight charge by DHL damn this is what I call service:)

No.With this one all settings were default (punch and timming).

i use 2s 2sp a123 4600mah batteries in serie and 7.4v lipo 8000mah 10c in serie too..
these last ones are weak in discharge force and heat a lot, the a123 are powerful and discharge is great too!!
i have to invest in more a123 or lipo, but since a few days ago one batterie explod right in front of my eyes maybe i will go to a123 again..
i will buy the neu or medusa or a new hobbywing complete combo, and in these case i stay with a spare esc.

thank´s and regards

Try zippy they are cheap n performances not bad.

If it's really not working send jack a email he will send u a new one with new firmware:)

Thanks

At first he replyed daily,asked for pictures of burnt unit,but since I've sent them I never got a reply.
Hope he didnt broke his keyboard :)
Now I have 2 ezrun bricks and a powerless RC8.
Did any of you guys got a replacement from HW?

I got my motor replaced. It had a broken magnet. sent a photo of it and they sent me a new motor. It cost me the shipping.

I got my new esc n motor:) try emailing him again. He still replies my emails

Any idea if the 3674 2350Kv ezrun motors are 2 or 4 poles?

What about the KD36 range of brushless motors? Are they 4 poles motors?

Oh and the KB45 brushless motors? Any idea if they are 2 or 4 poles motors?

No they r all two pole

Hi, but somewhere on the net I've seen a pic of a 2350kv (ezrun motor) with some sort of carbon wrapping around the magnets. Did I see wrongly?

What about the 44mm diameter ezrun motor? is it a 2 pole as well?

Yes it's all 2 pole, 4 pole will b neu n medusa

The KB 45 motors are also 2 pole!

I want a look inside the HW motors myself. My buddy wants a budget buffy system, so he may get the HW80 and one of the motors, probably the longer model, should handle the heat better?

Yes it shld handle better heat but also draw more amps

Seems like the difference between a L can and XL can feigao... Similar KV and the longer can will draw a bit more, but run cooler and thus more efficiently. So the amp draw ends up about the same... But the longer motor can run longer and will put out a bit more power.

Yes 80mm seems better by I was advise by medusa it's a overkill. That's y I stick to 70mm

80mm medusa is a good motor for a truggy or MT. Had a chance to use one on my friend's RC8t. Wheel stands any time and runs pretty cool. Way overkill in a buggy though. Was desperate one race day cause my 36/60/1600 was back at medusa for a new rotor + bearings due to bearing failure so I borrowed the 80mm medusa and raced with it in my buggy. Yep Overkill, but I was surprised that it spooled up rather smoothly even tho it had considerably more static resistance to turning the rotor by hand. This threw me off slightly over the jumps as it had more motor braking effect than my 60mm medusa and as such I nose dived a few jumps till I got used to it. Might borrow it again and get a massive pinion for a speed run just for laughs. I calculated 134km/h on 6s with a 36/80/1900 and a 25t pinion on my buggy. That's 10t higher than I normally run. I have the pinion already, gotta check if my motor mount has enough movement to fit it on. LOL.

Overall medusa motors are good for the money but keep an eye on the bearings cause they're small. Front bearing collapsed on mine after less than 6hrs usage. I will strip it down and check/clean bearings every 1-2 hrs from now on.

I run the 2350 kv model in my emaxx with a HW150A. The first one i blew up in 5 minutes of runtime, probably a mounting mistake. I may have used mounting screws that were too long and that bent the inner wire wich in their turn shorted with the magnet. Or just a production failure :)

Anyway I got a new motor from HW (GREAT service) en used shorter mounting screws. I had three runs up to now. One to test if everything works and two runs at full power. Constant high speedruns/full throttle in a park on long grass. I use a 21/62 gearing and 2X 2s2p 5100maH 25C lipo packs. The runtime was 13 minutes. the motor didn't get warmer then 51 degrees centigrade. This is with a heatsink and fan. The lipo got handwarm as did the ESC.
I think it's a great motor for bashing and it's a cheap setup. For racing I will use a medusa
