All flight controllers flashed and tested with newest firmwre before shipping. Aug,2020 Departing from Florida, U.S.A.  

B-12A Ice Blue series BLHeli-(OneShot)

B-12A Ice Blue series BLHeli-(OneShot)

Flashed with newest BlHeli firmware installed and tested!

(the newest firmware is compatible running conjugation with all 13.x.x firmware)

RTF B-12A ESC Run cool as ice when your ducking trees with the BL-Heli active braking version, are made for Racing MultiCopters - specifically to run at 2-4S. They also feature ultra light weight construction with excellent thermal properties for a ESC - the MOSFETS are specifically selected to run with the least amount of heat production and highest efficiency. For Cleanflight ,Baseflight, Tau Labs, MWii, any flight code which is OneShot enabled - these ESCs are OneShot auto-detect ready.

The RTF 12Amp ESC BL-Heli ships out pre-programmed and optimized for best performance -pre-configured- OneShot is included/Ready


Enable Racing Mode! (Dampened Light Supported)

Enable racing mode to change over 10 Settings for maximum performance: PWM Frequency/Damped, Motor Timing, Beacon strength/Delay,PPM MIN/MAX Throttle are set to maximum performance!  Pair with a Flip32 for automatic detection of all the advantages of Oneshot123


The main advantages of BL-Heli software is the use Active free wheel and active braking (PWM Damping) Dampened Light - 13.1 is OneShot ready for Flip32 - this actively slows the prop/motor down on one side of your Quad, while speeding the prop on the other - without "active-braking" the prop has to slow by inertia and drag alone - this DAMPING Light mode puts the brakes on! - the Racing Quad handles better - but you must also increase "P" slowly in 0.1 increments to see the full benefits. Boot-loader enabled! This means all the settings can be changed over the servo cable with a simple pro mini+ftdi combo



 The input capacitor has also been upgraded from 16 to 25V for ample operation.  Plus the added a heat-sink adds for even better sustained high current operation. Try to keep them in moving air is best. 

These ESCs will give your multi rotor quicker reflexes, less drift, and smoother flights. These are so fast, compared to standard ESCs you can double your PI gains! ALL ESCs are flashed with the most current version of the famous BLHeli Future software updates can be performed through the servo cable eliminating the need for complicated flashing jigs.
