Blueson A1 8S 70A 4in1 ESC, Pre-Flashed for Drive and Weapon!

Minimal Wiring with Maximum Performance

The Sequre Blueson A1 ESCs have been used by high-performance racing quadcopters for years, and recently have been adopted by combat robot builders. The key pain point with 4-in-1 ESCs for combat, however, is that they can be very annoying to wire to a receiver, reprogram, and use without a flight controller. Well, those pain points have been solved!

First off, this ESC comes preflashed with bidirectional drive settings on channels 1 and 2 PLUS single direction spinner settings on channels 3 and 4 (which should work with most if not all our hubmotors), making it easy to integrate into your robot. The stock drive settings are perfect for our Blitz Lite 2850 kV motors and are just a matched-kV change away from a perfect setup for any other motor.

Pair with our Blueson A1 Backpack to make wiring to an ER4 or R84 compact and easy, with an integrated LED and BEC to power the receiver with 5V. 

All the settings can be changed with our AM32 USB programmer, and our 8-pin breakout boards make connecting the programmer much easier. The breakout board also makes it much easier to wire up any external electronics you so choose, with your own BEC or receiver combo. The M1-M4 channels just need to connect to receiver signal outputs for CH1-4, and the receiver is powered independently (such as with one of our All In One PD boards).
