I’m new here and new to drones and ardupilot. Recently i bought an octrocopter made by rctimer with Pixhawk flight controler, and recent firmware. Its been third time i’ve been trying to take off the copter without any crash, with no luck unfortunately. I’ve been trying everything i could, ESC calibrations, GPS, COMPAS etc., even reset, erase Pixhawk EEPROM, no luck. Every time after take off copter starts to spining around and moves in a direction with all sticks cenetred, it feels like lack of control. i would appreciate any help, suggestions, log file analys.
Thank You
