Justme, if you look at my previous posts you will find that that exact problem happened to my twice!!!... I took of and the aileron trim was all the way to the left and the plane did a roll right after take off and crashed, the fuselage broke in 3 parts, I had to buy a new one. The second time it happened I was a bit more prepared and realized what was going on and saved my plane from cashing by adjusting the trims without looking down at the radio. A bit of luck...
Now I check the radio before take off and my radio is set so the zero position is where all the trims should go.
