Ordered these but changed quad size during midstream build... they were flashed by Timecop.

Asking $70 or best offer.

This is a 20A Brushless ESC with factory firmware replaced by improved version by Simon Kirby. 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.

In order to load firmware, a small portion of heatshrink near the motor leads is removed in some models of the ESC.

16MHz Resonator, 16kHz PWM frequency
Up to 600Hz PPM input
Immediate translation of input PWM duty into motor control, no smoothing or delay
Throttle range calibration available
Firmware update by USB adapter (not included)
Battery: 2-4S Lipoly / 5-12s NiXX
BEC: 5v / 3A (Linear)
