MicroAir 4-in-1 ESC (BlueJay)

Look, we know why you're here. You pushed your last ESC a little too hard, saw the magic smoke, and now you're frantically scrolling through product pages while your quad sits in a pile of shame. The MicroAir 4-in-1 is the reliable, Bluejay-infused hug your motors have been begging for. Whether you're chasing cinematic shots or trying to break the sound barrier in a car park, this ESC handles the juice without the drama.

Why You Want It

It’s pre-flashed with Bluejay 48K firmware. If you don't know what that means, it means your motors will sound less like a dying blender and more like a precision instrument. It supports Bi-Directional DShot right out of the box because we believe you deserve RPM filtering without having to sell a kidney for licensing fees. It's built for those who want performance but lack the patience for complex setup screens.

Specs

  • Firmware: Bluejay_0.19.2_JH40
  • PWM Freq: 48KHz
  • ESC Protocol: DShot300/600
  • Power Input: 3-6S LiPo
  • Continuous Current: 60A * 4
  • MOSFET RDS(on): 0.75mR
  • Current Sensor Output: 12.75mV/A
  • Mounting: 30.5*30.5mm (Φ4mm)
  • Dimension: 44 * 43.5 * 5.2 mm 
  • Weight: 13.5g

In the Box

  • 1x MicroAir 4-in-1 ESC

Compatibility

Works flawlessly with Betaflight, EmuFlight, and basically anything that speaks DShot. It fits into most modern stacks, provided you haven't filled your frame with hot glue and broken dreams.

Highlights

  • Bluejay Pre-flashed: Smoother than a salesman’s pitch.
  • Robust MOSFETs: Designed to handle your questionable throttle management.
  • UK Support: We're in the UK, so if it goes pop, you're not sending it to a literal island in the Pacific.

Notes

Ensure your airflow is decent. Even the best ESCs don't enjoy being baked inside a TPU coffin. Check your motor screws; if they touch the windings, this ESC will commit suicide to save the rest of your stack.

Disclaimer

Recreational use only. If you use this to fly over a stadium or build a sentient toaster, that is legally your problem, not ours.

Still Here?

If you've read this far, you clearly need this ESC. Stop overthinking the MOSFET gate latency and just add it to your cart. Your quad is lonely. Use code 'I-READ-THE-SPECS' for absolutely nothing but our fleeting respect. Buy it now and get back in the air before the British weather turns into a swamp again.

Great confidence booster for dad - techniques can be successfully implemented immediately after birth!
Format: Paperback
This is an excellent book! My husband read this book before our baby was born. Although I found a synopsis to be enough for me (no need to read a whole book for five main techniques), as an engineer, he really liked understanding all of the "whys" behind the methods, and understanding the reasoning gave him more empathy for our baby. My husband started implementing the techniques in this book immediately in the hospital right after the birth, and they really worked! It was extremely helpful for his confidence as a dad and for my confidence in him / us as we started the adventure of parenting (especially when I was recovering from childbirth in those early weeks). We have continued using these techniques for months, and they make a huge difference. Sometimes babies get overly tired and don't even know why they are crying anymore, and these techniques help to soothe quickly to get down for a nap. Truly, I do not know where we would be without a good swaddle and turning our baby on his side while swaddled, because he can be losing it completely and then the swaddle / gentle bounce calms him down very quickly. The one thing I wish the book did mention but does not is that it IS possible for a swaddle to be too tight on the legs - the latest research shows that babies need room to bend and straighten their legs for safe growth of their hips, so it's ok to do a fairly tight swaddle such that their arms cannot escape, but there does need to be slack at the feet.

SAVED MY SANITY!!!
Format: Paperback
I don't know why I didn't leave a review on this book as soon as I finished reading it! My daughter was quiet for the first week home from the hospital, but along came week two and around 8 pm one night she began to cry, and this time it was different, we literally could not get her to stop. She cried until around 4 am, and I was terrified that we had a year of colic crying ahead of us, but prayed it was just a fluke and that the next night things would be different. However, 8 pm rolled around, the crying began, and we had a repeat of a night full of inconsolable crying. I had never felt such all encompassing exhaustion in my entire life and I just prayed that there was a book that would have answers for me. So the next morning I took to Amazon and began my search. After reading reviews I decided to give this book a try - the length was perfect, thank you Harvey for getting straight to the point and telling us exactly what we needed to know! I was able to implement the S's the following evening at 8 pm when the crying began and I believed with every fiber of my being that it was going to work - AND IT DID!!! Simulating the womb experience was exactly what my daughter needed to soothe her overstimulated little newborn nervous system and she calmed down in less than a minute and fell into a blissful sleep that lasted until her next feeding, after which we repeated the process and she was asleep again. She was sleeping through the night after a couple of months, and we continued to use Harvey's method until eventually she didn't seem to need it anymore. This book was a lifesaver, I have given it as a gift at every baby shower I've attended since I first discovered it, and I'll continue to give it as long as I live!! This book could just as easily be called Happiest Parents on the Block - I am so very grateful that I found it when I did!

Ignore the sales pitch and absorb the advice
Format: Paperback
I agree with other reviews, great advice but the dr really pushes his products in it. I guess the guys gotta make some money. Worth the read though.
