First Glance – Bullet 30A are Tiny!

Width and length measure at 11.9×19.6mm, weights at shocking 1.6g (without wires and heatsink)! The Emax Bullet 30A is probably the smallest and lightest ESC on the market today.

It’s only 2/3 the size of the DYS XSD30A ESC.

Spec and Features

  • With wires and heatsink weights 4.9g
  • Current rating: 30A continous
  • Input Voltage: 2-4S
  • BB2 processor (busybee 2)
  • Supports DShot, Multishot and Oneshot ESC Protocols

It’s tiny yet has all the good features we love such as hardware PWM for smoother throttle response. The light weight heatsink (0.4g) can help cool down the ESC, also protects the PCB from prop strikes.


The 6A/12A are great for micro builds. The Babyhawk 85 micro quad uses the 6A version.

  • 6A: 2S only, no heatsink
  • 12A: 2S to 4S, no heatsink
  • 15A: 2S to 4S
  • 20A: 2S to 4S
  • 30A
  • 35A: 3S to 6S, No DShot support

I’ve used this ESC for a month now. They are great and tiny. However, the pads where the motors are soldered should at least be a permanent one for your set-up. I think those pads are not very durable and don’t last with several tinkering and soldering. After doing a single replacement of my motors, one of the pads chipped of and left a very tight part (less than 10% of the original size ) enough for me to solder the motor wire. It happened only in one of the four ESCs. After that experience, my suggestion is to just cut of the wire of the motors and leave that soldered part and use that as your replaceable connection whenever you replace a motor. Other than that, I really like it because its very tiny and its powerful. I am not a fan of a 4 in 1 escs hence this is the best for me. Cheers!

Just bought these and installed them and realized there’s more work to be done on these because they don’t run out of the box. I don’t see a website on the box and no manual included. What are the magic steps to get these going? Where’s the info?

I cannot find any information about flashing these ESCs. I’m running into an issue that when I plug it into the computer and I try to run blheli Suite, blheli Suite is not picking up the ESCs. My Motors Jitter when I plug in the battery but they do not make the full song just the first couple chimes. They will not calibrate they will not spin, they say they arm in BetaFlight and are spinning but they won’t actually do anything. I’m completely stuck anything would help. Thanks. I’m hoping they aren’t fried or faulty.

Hi Oscar,
I own these ESC however I don’t know if I can run at 32Khz with Multishot… There is no info about this on the specs…
Since it has a BB2 chip it should be able to run a 32khz…
Do you know this info?

Thank you

Oscar 16th May 2017 - 3:15 pm

yes it can do Multishot :)
but just make sure your quad is as low noise as possible.

Yes there is a way. I have no issues on using them on 5 and 6s with dshot. Please give me a while on making a picture of it.

ok so im about to change every quad i have to these 30a tiny beauties. bought 4 to power emaxs new 2306s.(found a store in a small town has a bunch, bought 6, 2400kv)..your pic does no justification. lol…they are even smaller in person..but before i do…its hard to believe that 30A is in such a small package..is there any info on testing…..but then again look at emax.. other companies are gonna have to re-invent the wheel to even smell the tire smoke coming from emaxs progress. but are these tiny things the emax we are seeing today? will they last?

I had one of these catch on fire after performing great for..1 week. Hopefully just bad luck.

Richard Revell 23rd March 2017 - 8:09 pm

SO on 5s there is no Dshot support with 5/6s How about Multishot or PWM which is what im interested in as want to runs these on 5s :)

Oscar 24th March 2017 - 12:58 am

Yes the 35A version supports upto 6S and Multishot
