Man I hate it when that happens on a first flight on an expensive plane
Doesn't really want to make you rush out and fly it again for sure.
Obviously the best way to tell would be to us an incidence meter, most can be used on the motor as well as the flying surfaces.
I guess you could level the wing with a small bubble level and then check the motor prop shaft with the level.
If it pulls to 90 degress that fast I would think that amount of upthrust would be quite noticeable.
If it appears close then go ahead and move the cg towards the nose. Maybe someone who flys one can speak up with some cg measurements for ya? Good luck
