I am currently having issues with calibrating the ESC’s and I believe this is why I am having trouble with the motors starting at the same time. Once all the motor are on the drone seems to be responding well to the input commands.
The motors I am using are prop drive 28 1200kv motors (https://hobbyking.com/en_us/ntm-prop-drive-series-28-26a-1200kv-286w.html) The ESC’s I am using are (https://www.amazon.com/gp/product/B00E95VG2I/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1). I am also using a raspberry pi 3 B+. the receiver and transmitter I am using is Flysky FS-i6 6CH 2.4GHz AFHDS RC Transmitter w/FS-iA6B Receiver for RC Multirotor Helicopter Airplane Glider Quadcopter (Model_2) (https://www.amazon.com/gp/product/B07CXL9LCT/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1)
Bellow, I have attached a video link to a YouTube video that shows me trying to calibrate the ESC’s but the NAVIO2 never enters ESC calibration mode. I am able to set up and calibrate the accelerometers, level, compass, and radio, but not the ESC’s.
