A good esc

Feb 26, 2018

It is a perfect esc for your quad. It works perfectly. It is tiny and weights nothing. I recommend you.

Un buen variador

Jul 18, 2017

Es un variador diminuto y muy potente. Yo utilizo 6 variadores en mi H550 y no he tenido nunca ningún problema. También tengo uno de reserva pero no lo he utilizado aún. Responde rápido y al instante.
Cuando termino de volar siempre están fríos.
Lo recomiendo.

Great little ESCs

May 24, 2017

I'm still new to the world of racing quads, so I haven't used a lot of ESCs to be able to give any kind of in depth comparative analysis, but I can tell you what I like and don't like. Until I bought these, the only ESCs I ever used were Afro. I got 4 of them in a kit, and bought 3 replacements in case of burnouts. Of the 7 Afro ESCs I have purchased, only one still functions, so compared to Afro, the ZTW Spider is much better. They're also literally half the size of an Afro 12 amp ESC. They seem to run cool, and they do what they're supposed to do.

Of the two brands of ESC I have used, this one is definitely the best, so if you're torn between these and Afro, I highly recommend the ZTW Spider Series.

Excellent ESC's. They have been rock solid performers and never even get warm running the Multistar Mini Monsters on 4S.

Bought a bunch of these during the last sale. They're terrific ESC's and appear to be more reliable than the DYS SN20A's. The only thing I don't like about them is the difficulty in soldering to the motor wire pads. They use a horrible lead free solder and it's a pain to remove the stock wires. They should sell these with a wire-free version. The pads are really close to the chips so it would be easy to accidentally damage a component.

Got these in the mail, excitedly soldered them in. Made sure polarity was right, plugged into my SPRacing F3, plugged in the battery and... instant smoke from one ESC, which took out a motor with it. Now the remaining 3 ESCs get incredibly hot just from having a battery plugged in. I've quadruple checked polarity, and it's all right. As soon as I plug them into my FC they start heating up rapidly.

Not great.

Well this is awesome, it is smallest than a 12A ESC, lighter and I hope that can handle the job. Its measures: 22x12x5 mm and weighs 5 grams. Motor wires and battery wires has about 55 mm of length and Rx wire has 165 mm of length including connector. Heat shrink tube is transparent which is very nice and I am very excited to install them .

Recommended, tiny size honestly about half the physical size of an Afro 12A.
