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.

You are going to have to review the dataflash log by hand.
I had a similar problem with mine. My radio was setup in heli mode instead of acro mode. Once I setup acro mode this spinning stopped.
