Hi.. Got my fc40 2 weeks ago , and at first flight i lost control after about 5 min and it steered into a tree and out, i panic and turn of transmitter and i came back to me, luckily! So i thought i was doing something wrong since i was a beginner! But now it happend again, it have happend 4 out of 7 flightS. So this is what happens I start it in gps mode and get good signal, green blink only. i fly around some minutes i go up a little high and come down! seeing that it wont stay i same position even gps mode is on and no wind it drifts away, i go little up and it starts to live its own life.. i cant controll it with my transmitter, its not working it flies it self towards some trees, i try turn off transmitter to trigger failsafe but that doesnt work either so i crashed into trees and falls some meters and out, still i cant use the transmitter, so i go after it and grab it in air and it stops! i reset it and try i low altitude and back to normal i fly it again! Can anybody help me? im afraid to use it beacause of this..
