F-20A Fire Red series “Naked” edition SimonK-(RapidESC)

Gold standard ESC for multirotors. Free reflashing if new firmware comes out, flashed with the  most currect firmware.  ESCs now have the bootload firmware which can be upgraded by using TURNIGY USB Linker.

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

For pancake motors such as the Tiger MT-4006, ect,  now have the option to have the analog filtering removed, these modified PCBs further enhances pancake motor performance.he result is that timing synchronization loss from motor saturation during extreme instantaneous acceleration becomes avoidable, and start-up of higher-inductance motors is much smoother.
