These micro ESCs make for good “project car” speed controls. I got them so I could juice up some toy-grade cars that need a little more pep in their step, and for that, they’ll work perfectly. If you want to put them in a car you plan to use more seriously... well don’t be surprised if something goes wrong.They don’t have a low-voltage cutoff, so be careful if you’re using LiPo batteries. Stop driving as soon as you notice a drop in speed. They do have a BEC which hovers around 5.5V, but it’s only good for about 800 mA. Fine for a micro servo, but maybe a little weak for a “standard” servo.Power wise, the 20 amp rating of these ESCs might be a little optimistic. They have four MOSFETs, the minimum you need for a bi-directional motor controller. The two P-channel MOSFETs have model number P2003ED, which has a maximum rating of 30V and 36A. The N-channel MOSFETs are labeled 0201NY, but I cannot find any data on those. One product page claims they're a clone of the IRF3205, which has a max current rating of 110A, but I highly doubt this chip can handle that much power. It would be limited by the 36A P-channel MOSFETs anyway. Every chip on the board looks like it came from a different manufacturer... so they might not be the most trustworthy chips out there. Those current ratings also assume that the MOSFET is sufficiently cooled, and these ESCs have nothing in the way of heat dissipation. I honestly wouldn’t try pushing this board past 10A.I have to knock off a star for not having a low-voltage cutoff. It’s a computerized ESC anyway; it would not have taken much effort to include this critical safety feature.Still, I cannot deny that they all did work, and are pretty responsive both forward and reverse. They’d be fine in a 1/18 or smaller car. They’re a little big for a Mini-Z, but they might fit if you remove the heatshink casing and redo the wiring.

We have a few older toy grade RCs laying around, but we cant get rid of them because they are so cool, like a grave digger, and other monster trucks, so my son has been looking for ways to bring them back, and this was the answer.They are cheap, universal, and so small you can install them in anything really.
