Chips on EFM8BB21F16, 48MHZ Greatest  .
BLHeli_S  is designed for superior performance in multirotors, and uses hardware generated motor pwm for smooth throttle response and silent operation.
Small size combined with light weight  for easy installation. 
- The code supports regular 1-2ms pulse width input, as well as  Oneshot125 (125-250us), Oneshot42 (41.7-83.3us) and Multishot (5-25us) .
The input signal is automatically detected by the ESC upon power up .
- All codes use damped light mode.Damped light does regenerative braking, causing very fast motor retardation, and inherently also does active freewheeling
- The code supports features to prevent sync loss. There are tuneable parameters that can make the code run well even in the most demanding situations, although default settings will work
- excellently in normal operating environments
- The code also supports a beacon functionality, where the ESC will start beeping after a given time of zero throttle. This can be very useful for finding lost crafts.

The Wizard stock speed controllers(esc) seem to work well under normal flying conditions, I have 2 for racing the third one I bought and programed for 3-d flying hovering upside down and other maneuvers. Two of the stock 20amp speed controllers caught fire. I replaced all four with the 30 amp controllers, so far they are working well.

I'm new to the hobby. Destroying the most expensive parts I can buy seems really stupid to me. These ESCs get the job done and don't cost you an arm and a leg.

These are so light and small, I cannot believe they are 30 Amp ESCs. I've only run them a few times on my quad (4S battery) but I have flown full out and they were barely warm. If they last, I will be using more of these for other builds.

Third or fourth picture is misleading you to think that this ESCs are not Dshot capable (if you know what to look for), however they are and no need to modify them or flash them with new firmware. They are so quiet (makes you think that there is something wrong with them). I would recommend this to anyone who is on the budget and is looking for quality.

I was worried about thes being too "cheap" but they look great and run great. They don't run hot on a rs2205 2300kv/5045 bullnose setup so I didn't bother with putting them on the arms for air flow (they stay inside the body of my quad). They also helped me push my quad past 100 mph: https://youtu.be/V7cHO1DwbYA

I've had these since early Jun of 2017 and have flown them almost everyday. They're an awesome bang for your buck. They take a serious beating and always get back up!

A great ESC for the price. Low profile. This is the best ESC I have seen. the pads are well spaced and it runs DSHOT out of the box.

I been using Simonk K ESC for awhile. I have to say... This product is a game changer for me when I use dshot 600. You could tell the difference in performance.

Bought these to replace the original ESCs in my Wizard 220. I didn't want to encounter issues since I have read, watched and realized that the original Wizard 220 can have a weakness in the ESC performance. So I will replace them with these Racerstars to avoid the potential hassle. Racerstar ESCs are proven to be much more reliable. In cheap quad builds, these should be just fine.

30 amps is what you need now with the powerful motors. Don't skimp out, this is my second purchase and I am not dissapointed. Look at my picture to see how to wire them up.

The racerstar motors and esc combo are perfect for getting into quad racing, or just building multiple racers so you're ready for race day crashes. Great price, great stuff.

I love how well these escs work. Very smooth and never get hot. No issues with noise in my video stream although I run a 1000 mF low ESR cap. 2 out of the 4 still had the signal cap installed. Fairly easy to remove so I can run DShot600.

One of the four had a different chip and that one randomly let out the magic smoke after many good flights. Replaced it with a spare and good to go again. I don't know if the odd one was a fake but it seems like a big coincidence that one randomly failed. Other than that I am very happy and will keep buying theses for most of my builds.

Hooked these up this weekend on an RMRC frame. Have racerstar rs2206 2200kv motors, and seriously dodo flight controller. Flashed Betaflight, and these ESC's flashed to latest Blheli_s firmware. Had no issues, everything runs super smooth. Will run 6" props. Love these I already ordered some of the 35A ones.

Good escs for the price. Sticker on top is cheap paper and easily damaged. Gloss sticker or under the heat shrink would have been better. Bottom is not totally flat so it sits at a small angle which isnt noticeable but may cause issues in a crash.

They're small and light, and they work great. I have close to 10 hours of flight time on them and they've been working perfectly. They're actually more capable than my flight controller.
