Ill finish assembly and see what happens. Im very anal about things and I let little things bother me. Ill just finish and put my servos in and take it from there. But I will make sure to ALWAYS check slot alignment on future planes. This is the 2nd Hanger 9 plane ive had this problem with. The first time - Pulse XT - Horizon sent me a new wing. But Im doubtful they would do it again. Should I try again?
