I received mine over the weekend and decided to install it into my x1-cr buggy on 5s to see what happens. I was running an 8XL/MM set-up on 4s at 16/48. Speed was good, but on 5s my MM would always shut down. Tossed this in there and it ran great for about 5 minutes. I didn't run anymore than that, because I didn't want to push it too much today. No problems on 5s with the stock caps so far. I'm very pleased with this esc. If it can push my 1/8 buggy around, then I'm sure it'll have no trouble in my little boat.

I just ran the 30a and 50a versions around with a 4400kv outrunner. Startup was decent, but I noticed a lag as compared to nicer controllers. The startup when wedging a tire was really bad too, along with the low speed resolution. The larger ESC will have a place until the MMM comes out, but the smaller ones aren't really worth the time IMO next to a M25 or Sidewinder. I just need to find some little heatsinks for my m25. These MF esc's may do better on 2 pole slotless inrunners. The motor that came with the 120A controller looks decent. The airgap is pretty wide though, so I imagine the efficiency isn't all that great. Good cheap motor though I suppose.

The size of the 120a controller really suprised me. Sucker is a Hoss!

Here are some pics of the esc in my buggy. I'm debating on keeping it in there. Although its not the best quality, its not bad either. I do need another fan though... this esc really is a beast in size. The fan is 30x30mm and is perfect for the MM; but this esc makes it look... well... rather lacking.

The motor is a hextronic I think. They aren't bad, and for the price they are outstanding. Don't know what I'm going to do with it if the esc stays in the buggy... but its nice to have around. Could be an excuse to buy another car....:lol:

edit- one more thing I noticed. Even at the lowest start power and timing, my car has very little low end control. An adjustable throttle curve would be nice.

:lol: The second sentence almost made me fall out of my chair from laughing so hard!

So the FET's are 25V right? They look easy enough to replace if you can find some 35V or 50V ones in a TO-220 case. That would be pretty cool. I would actually pay $85 for an ESC brain board. But getting a motor with it is nice, NVM the LCD programming card.

cheap esc
 

i thought i was the only cheapo around?? i have been trying out one of these my self. im running it on my revo with a neu 1515 2.5 on 6 s , so far its working . but on the third hard pass it blew my tranny. but by the pictures yours looks different, ??? yours looks like it has more caps than mine ?? my esc has 2 - 35 volt 220 uf

your looks like it has more than 2 ?

Yea, I added the caps in myself, which are 330uF 35V.

I had two suggestion today for replacement fets.

Fairchild FDP8860 and IRL3713.

Current fets are IRL3803. Any of you guys know which of the above would be a better choice?

nice, a $50 esc on a $300 motor:mdr: glad to hear its working though.

I reckon GriffinRU would know which fets are the better choice- can you look up the specs on digikey?

Yea, just type in IRL3808 in digikey.

yes i know thats bad but by all the post of people complaining about quarks and mgm esc ., i said why not try it ?

wow that seems like a hell of a deal. $105 to your door for a brushless system for an emaxx. Heck I would be willing to risk it. It is pretty nice they are using to-220 fets those are easy to replace.

i plan on getting one, but i'm waiting for snellemin to work out all the bugs in his first.

I would try one of the following:

IRF2804 (Just seems to be a monster of a FET and it has lower resistance and 40 volts to be on the safe side)
IRF2903Z (Same voltage as the stock unit, but lower resistance and 20A less than the above mentioned)

Thanks Lutach!

Are you guys also looking at switching speeds? High current, high voltage, and low resistance is only part of it. And, make sure it's an enhancement type (not a depletion type)...

Yeah and not every kind of driver can drive those Fet's

this is getting good , i beat mine up some more today and its still holding up no problems.

I will agree with Lutach, IRF2804 is a good choice. (IRF1404 not bad also)<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>
IRL3803 is not a stella performer, but cheap.<o:p></o:p>
The only place I would worry is boost-charge capacitor, replacement FET's have higher gate capacitance by 10-15% and require more charge.<o:p></o:p>
But in general with T0-220 package you cannot draw more than 75A from FET, so the lower Rdon in this case better.<o:p></o:p>
Just do not short FET's mounting/heatsinking tabs!

Looks like the ebay seller is no longer carrying them. Anyone know where else we can pick one of these babies up?

I can get them, but they hit me with a MOQ. I was going to get them, but if I can't test the ESC first, I can't really put my money o them just yet LOL.

I sent them a note and they said "after chinese new year" so Feb 15th I think.

I got a 50 amp and a 120a I don't want anymore. Tested the 30's and didn't like the startup very much. You would need a program card though.

Shoot me a PM with price on the 120A please.

Just a little update. We finally got a little break in the rain so I took my buggy out for a nice run in the park during lunch. I've been wanting to try this out in a huge area for over a week now, so food was put on the backburner. :smile:

The park was soaked from the week of rain we just had, so the grass felt similar to a saturated sponge. Lots of visible puddles and tons of mud. Perfect for a little bashing. I had gone through and waterproofed a few of my bashers over the weekend since I was getting bored, and luckily I did the buggy too.

I got about 15 minutes of solid running on a 5s 4800mah hyperion lipo. The esc performed beautifully! I had no problems at all during the run. The temp on the esc was under 130*F after the run and I didn't even bother testing the motor or battery since they were warm to the touch, but not hot. The ice cold water on the field probably helped a lot. Its 45*F in the sun, but at least its sunny (yeah I know... its not really cold, but hey I'm used to so cal weather).

I have to admit, I'm liking this esc more and more every day. For the purpose that it serves (bashing), this esc is great. Now all I have to do is figure out what to do with the motor.... I was thinking about getting a kyosho 1/10th dbx pretty soon. Anyone think this motor could power it?

You guys got an exact price on this ESC? I cant seem to find just the ESC on ebay. Im looking into this for my E-warhead. Save some dough.

I bought mine at $85 + $15 shipping.

here a quick video I put together today.

Have you even read the thread?

http://www.rc-monster.com/forum/show...7&postcount=62

As I said before Im a skimmer... So its $85 for the ESC. That a little more than I was willing to spend for it. I will either look into a modded MM ESC or the new MMM.

well.... its $85 for everything. the esc and the motor. The motor is probably worth $20 if sold off.

The same motors are being sold for 50 bucks on ebay right now.

Right Here

Trying to be sold you mean. Not a bad price for a motor, although they don't have much power at all.

I only use the motor to benchtest the ESC's. It's smells funny when it's running.

http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA:IT&ih=011

is this the same thing?

yup, looks like it. Different seller though. and the price is higher, since it looks like this seller will stick it to you on shipping charges. lol... $20 for domestic priority. what a joke.

That guy is charging $20 big ones for shipping? He is trying to get rich quick I think.

God, thats what I hate about some ebay ad's. They seem like an unbeleivable low price and then you look at the shipping price and its way to high. Pretty sad...

At least ebay has introduced a new sorting function which allows you to sort based on price + shipping costs. So even if the seller tries to hide the shipping cost, it still affects his/her overall sale price.

Bad news fellas. I think I smoked mine today. :tongue:

I went to the park again today and got in about 5 minutes before it died on me. I most definitely thermalled the esc, because when I checked it, the heat shrink surrounding the esc was melted out of shape. I also lost power to my servo, which leads me to think the ubec is toast, but I need to check that one later tonight. I was running a 5s lipo and 16/48 on the gearing. It performed perfectly two days ago, and for almost 20 mins solid with no problems. So I don't know what went wrong today????

As far as the esc goes, I don't know what blew. Maybe a cap, but not sure since I don't know electronics. I'll take some pics of the damage later tonight or tomorrow, but I guess the MM is going back in the buggy now. :no:

snellemin, did you get yours figured out?

Hi,

Check it out. You might get some "warranty" coverage but I doubt it.

If you can't get the seller to stand behind it, take some pics of the carnage and give me a good description. I might buy it from you if you give me a good deal.

I'm really curious about the construction of this ESC. I might be interested if the brain board is still good.

I wonder what happened to it? Hmmmmm......
