Introduction

Welcome to my overview and first look of the Wraith32 BLHeli_32 ESC.
Thanks to Airbot for sending me these ESC for an overview!

Before heading further into this overview please take into consideration that these ESC are a pre-production test sample that are not representative of the final product in any way.
They cannot be updated to the final firmware neither have functions like telemetry and current sensing working as of now.

Specifications

  • BLHeli_32

  • ARM 32bit MCU

  • Build in Current sensor

  • On-Board RGB LED

  • 2-6s LIPO input

  • 35A continuous (50A burst)

  • 15*30mm

Unboxing

Once I opened the package I was greeted by a letter explaining that this was a test sample and the limitations that it has.

A small BLHeli_32 manual was also included, of which I will disclose the first page.

Closer look

The ESC packaging was very simple, just an antistatic bag, no cables, or anything.
Remember this is a test sample ESC.

As you can see on the top side of the ESC, you have a current sensor on the bottom, as well as big solder pads for your main battery leads.

On the bottom side you can also solder if you wish to.
This is also usefull in the rare case a pad is ripped off the PCB.

User experience

As of today (10th of May of 2017) DSHOT1200 is functional, but can only be used on F7 boards.
Current F3 and F4 boards aren’t able to keep up with the increased PID calculation speed.

Also, the only way to connect to these ESC is via an Arduino since BLHeliSuite does not recognize them.
This being said, this ESC works perfectly on DSHOT600 with no desyncs and once DSHOT1200 is working 100% I’ll be sure to try it out.

Soldering to the pads was a dream. I’m a fan of bare ESC so I can cut my own cables to length.
The only possible downside would be the GND and PWM pad, which I found a bit small but workable nonetheless.

Below I have linked some DVR footage of a friend flying the Wraith32.

Ending thoughts

Would I recommend that you jump on BLHeli_32 once it releases?
No. Sadly it will probably be a "green" software in the first times and it being closed-source is a letdown for me.

I’d recommend you’d wait some weeks at least to get some solid feedback from early adopters.

Pros:

  • Runs BLHeli_32.

  • DSHOT1200.

  • Small size.

  • 35A capable.

  • 2-6S capable.

Cons:

  • Early adopter fee may be high. (early software may have bugs)
