I connect my drone, it is the engines are accelerated and takes off without me having it. Anyone ever had this problem ???? Anyone know what's going on. I've done the GPS calibration.

What do you mean by "takes off without me having it"? before take off the motors need to be armed.

is already everything. this happens in Mod 2, Mod 1, is already working properly. Thank You

The set up is where 50% throttle is on to get into air, when satellite are locked, start motors, set toggle to gps, the copter will stay at one place just apply a little power, set fly home too just in case you need it if you get desorented just switch to fly home, you can take over any time. Youtube has videos on setting controler on speed of control

John Moore explains in this video how to calibrate the transmitter for each of the ESCs to balance them:
