F-12A-HV Fire Red series High Voltage OPTO (2-4 Cells) BLHELI-(ONESHOT)

Flashed with newest BlHeli 13.2.0.2 firmware installed and tested!

12 Amp High Voltage RapidESC is settings the industry standard for the Go-To ESC for any mini Quad on 4s. OPTO – less EMI in the multicopter frame and less heat – you get a lot of electrical noise from 4 to 8 high amp uBECs in a radial pattern at the centre of your multicopter. less heat. less chanch of failure.

These are the optimal flash-able ESC’s for multirotors. They are all flashed and freshly wrapped with Clear shrink to show off all the PCB greatness.The F-12A HV ESC’s have been tested to the tee, up-to 20.5amps all day long when used with a 2208-1800kv, 6×4.5 hq prop, showing an impressive  1050 grams of thrust.

Super-fast throttle response, which makes your quad fly the most “locked in” feel possible. Best bang for your buck on the planet. Every ESC here is sold pre-calibrated on the throttle range so all ESC’s start and reach full throttle at the exact same time

Simply put the best ESC you can get for your multirotor. 

• All N-channel FETs
• External Oscillator:
• Boot-loaded Enabled

Flashed with the famous SimonK OpenSource Firmware for super-fast throttle response, which makes your quad more responsive and “locked in”.  These  ESCs do not overheat, burn or lock out – unline many other ESCs flashed with the SimonK firmware.

These ESCs are completely re-designed from the ground up. Flashed with the famous SimonK OpenSource Firmware for better throttle response . New firmware means direct, linear throttle response, making it suitable for multicopter use. Up to 600Hz input rate is supported, with immediate updates to motor pwm duty. Each ESC is tested with a motor before and after loading new firmware.

The the external 16MHz oscillator line up exactly with the numbers in microseconds, but the internal rc oscillator ones will drift quite a bit based on temperature.

The ESCs use only N-channel FETs have the advantage of lower resistance, less losses and hence more efficiency.

All N-Fet:”The ESCs which use only N-channel FETs have the advantage of lower resistance, less losses and hence more efficiency.”*

External Oscillator:”An external oscillator may supply a more consistent timing signal and steadier motor speeds” “but the internal rc oscillator ones will drift quite a bit based on temperature.

These ESCs are a revision of the nearly-perfect F20A & F-30A ESCs with high quality board layout and components to make them perfect. Do not settle for anything less.

NOTE: This firmware does NOT check battery voltage or ESC temperature. Always use a LiPo alarm and monitor pack voltage while using.

NOTE: These are not I2C ESCs and as such are not directly compatible with Mikrokopter-style interface, however they can be used with I2CPWM converter
