Has anyone ever used one of the brushed esc's?http://www.ebay.com/itm/320A-Brushed...item46014ffb29

785boats

Yes I've got one. Works fine. But it is no way rated to 320A. Probably 15A max. I mean, just look at the wires & the Tamiya plug on it.
I run 3 little 400 motors on mine in a model of the Bismarck battleship.
Cheers.

ok well im thinking of running two 380 or 1 550 but really 15amps? 3 400 motors have to be pulling a lil more than that or is that not so?! And how many volts have you ran through it?

Got RPM

That ESC is a joke. A low volt (7.4 volts) low amp (15A sounds about right) controller. Either the 320 amps is a typo or that is the amperage it takes to make it blow the hatch off the boat. What can you expect for $11 when REAL 300 amp controllers cost hundreds?

I can actually expect alot. with alot of stuff on the market thats expensive most the time its the name that sells not the part.

785boats I was wondering do you have one of these also?

It looks just a tad different im wondering if the only difference is the fan, heatsink extra motor connection and the capacitors? When mine gets here im questioning tearing off the enclosure epoxying it and encasing it in plastic with water taps to cool the whole unit as a complete cooling system. Also going to upgrade the wiring on the board between the fets and in/out wires before epoxying.

Got RPM.
The ESC isn't a joke, but the claims are. It is really quite a good little 7.2V ESC.
Those Amp ratings are calculated by adding up the current capability of each FET in the ESC. A common marketing ploy for cheap Chinese manufacturers.

The 3 'low drain' 400's draw less than 15a total spinning a 30mm 3 blade, fine pitch prop each. I only run the boat on 6V. But I must add that I did replace the plug with a Deans plugbecause I know that the Tamiya plugs melt at around 15-20A.
The modelof the Bismarck is 1750mm long & carries about 10kg of ballast.

I don't have that other ESC you posted, but again, with the small wires & the Tamiya plug, 15 to 20A would be the limit. But the ESC itself may be able to handle a few more Amps. But definitely not 320A

Here's the Bismarck.

785boats thats a nice model moves pretty fast. My esc showed up today. going to do some upgrades on it to keep it waterproof, cooled and more efficient.

1. Going to epoxy whole esc in thin layers to prevent possible damage from epoxy pulling anything out of place while drying.

2. Upgrade gauge of wire to 10 or 8 depending on what i have at home.

3. Add solder and copper strips to locations of high current in photo.

4. After im sure it is sealed im going to encase it in a clear plastic box and tap it and run water through it.

Im questioning running 14v through it... hehehe

785boats

Don't run 14V through it. it is a 7.4V (2s Lipo) Maximum voltage. Before you make any alterations to it, make sure the thing works first.

diy-pro

No 14v aww man I'm seriously wondering what the difference is between this and the high voltage one. Ill take you suggestion and not do it till my second one gets here. As far as that goes have you ever heard of anyone epoxying and sealing an esc in a water case to cool it? I'm using a softer epoxy so I have no worry of it cracking.

diy-pro

Ran 14v today ran fine will upload pics of "my" water cooling job which is way better than any heat sink.

diy-pro

Ran 21.6 v through it yesterday

diy-pro

Why does this thing take 21.6v?!!!!!!!!!! Runs like a beast wish my phone internet would let me upload photos of my cat but it doesn't x_X. Going to order another soon as my other one nevered showed up and I was refunded. But when I do I'm going to throw a 28.8V curveball at this bmf

Hey diy,

I was thinking of getting this same esc, and running 9.6v, and a titan 550 12t motor on my rc car. Did you buy the high voltage one or the regular one? Does it need to be programmed to the transmitter? Does it work well no problems? Any help would help.

Thanks,
Greenway

diy-pro

I bought the regular 7.2v one. It runs great for the price but does not have any settings. I can personally say i ran this in a boat with 21.6v lol. I dont see why it wouldnt run ok with 9.6 in a car. Watch the temps tho make sure the fets arent burning up

Team GxG

So what's the verdict on this ESC? I'm looking to get an ESC that can run dual 380s in a boat. I'm planning on using 3 18650 batteries in series, which will be a total output of 11.1V. I will also use the standard 7.2V NiMH batteries. Any foreseeable problems with this setup?

diy-pro

It could easily run dual 380s. I only purchased one but i even ran 28.8 volts through it with no load for maybe a min on and off the throttle with a 700 motor on the line. I am quite impressed despite the slandering of cheap chinese products i give it a hundred stars. One thing if you do give it higher voltage i would check your bec voltage before hooking up a reciever. At 21.6v it was 6. something but at 28 spiked up to 6.9 which most would say is unsafe for a reciever and highly un recommended for a servo as it will create a ton of heat
