A while ago I designed an edf f4d-1 skyray and decided to test fly it but ran into a weird issue. Right after launch, the plane would immediately pull up until it was inverted and would continue to fly like that. The motor was not mounted perfectly as I hadn't designed a mount or a thrust tube yet but, I feel like any imperfections in regards to thrust angle would not result in this kind of behavior but rather a continuous turn. I figured that the wing, battery, or motor position caused this but everything seemed fine. does anyone know why this would happen?
