$10 320a Brushed ESC Review

Review by Hunter Wick

When I was out on the prowl for a decent brushed ESC for my new build, Project Mini Clawz, I couldn't believe my eyes when I found a $10 ESC rated for 320 amps! This review will discuss whether or not this product was worth my ten bucks.

Ease Of Installment - 8/10

When it comes to putting something new onto your ride, you want it to be as quick and painless as possible, right? I found that this ESC was just as easy as any other to install, and I've done a lot. All that is needed for installation is some heavy duty double-sided tape and a rag to clean the area where you plan to stick it. The only reason that I took off two points here was because this ESC comes with an external switch. I hate external on/off switches. They are just one more thing to go wrong and also something else to install. I would like to see a new design featuring a built-in switch in the future, so that installation would go a little faster.

Durability and Performance - 5/10

Considering that this thing is rated at 320 amps, I was kind of skeptical that it was an accurate rating, and with good reason too as I would later found out. For testing I installed it in a Traxxas Rustler with some aggressive 2.2 tires on it. The ESC powered a Venom Fireball 17t double wind re-buildable brushed motor. For a battery pack, I ran a 2s LiPo. To be fair, the instructions say to not use anything above 7.2 volts, and I ran a 7.4v pack. During testing, I found that the ESC heated up tremendously, to the point where it would burn me if I touched the heat sink. This was just plain ridiculous. A truly rated 320 amp ESC should easily be able to handle what I put it through (nothing more than driving around on road and in very short grass), so I think it's fair to say that this ESC is not accurately rated. This ESC would probably be fine if only run on a 7.2v pack and with a very low powered motor like on a crawler, but still. I kind of thought this might be the case even before I started, though, because I have seen this same ESC on the internet multiple times with several different ratings. Obviously, I took off points because of the fact that it did not perform nearly as well as it should have.

esc 2

Value - 8/10

For just over $10 USD, this electronic speed control was a decent deal. I think it would be a good buy for a just-for-fun scaler or crawler (something that uses a motor with low current draw), but not for anything that you want high performance out of. For $10 you might think this a great deal, but keep in mind that you can buy a much more capable waterproof Traxxas XL-5 ESC with a low voltage cutoff which allows you to run LiPo batteries safely for around $30 off of ebay. Because of this reason, I took off one point. The other point I subtracted was because this ESC came with a Tamiya connector (also known as a Molex connector). While these are fairly common, they are just about the worst connectors to use nowadays. They feature very low current carrying abilities and wear out rather quickly. I would like to see some Traxxas connectors or Deans connectors used in the future, as these would allow the ESC to feature better performance.

esc 1

At the end of the day, I really don't have any use for this speed control. I already had a couple name brand ESCs lying around, so these really don't have any space to sit. If you're low on cash, and I mean like $10 budget kind of low, then this ESC will work, but don't expect more than your $10 worth out of this thing, which I think goes along with the 7/10 final rating.
