BLheli and KISS ESC are supporting this new protocol already.\r\n-> https://www.rcgroups.com/forums/showthread.php?t=2756129\r\n\r\nAdvantages (as described by Felix on rcgroups) compared to the most used analog signals like PWM as also oneshot125 or 42 are:\r\n- no signal jitter.. if the FC sends 1375 the ESC will receive 1375\r\n- high resolution (2048steps)\r\n- no oscillator drift (nomore calibrateing ESC's)\r\n- more robust against spikes\r\n- safer as every singnal has a CRC (cyclic redundancy check)\r\n- maybe later some goodies like having the ESC's beep with the buzzer signal or things like that.\r\n\r\nSince arducopter aims to support smaller/racer frames as well i suggest to add support for Dshot.\r\n\r\n#### Platform\r\n[  ] All\r\n[  ] AntennaTracker\r\n[X] Copter\r\n[  ] Plane\r\n[  ] Rover\r\n\r\n#### Airframe type\r\nall\r\n\r\n#### Hardware type\r\nPixhawk\r\n\r\n"}}
