Although both moved to an up position. As soon as it achived flight speed up & over it went. The one side up more than the other caused it to do the barrel roll.
I'll have to check the movement of the control rod when I get home after work that could be the case. However she lifted off with no input, but i do keep my thumbs on the controls so maybe i was touching it a lil and not knowing it. Thanks for the input. Another reason why I should've added a carbon rod joining the two.
