I made very sure to not miss the slits and took my knife and slid it from side to side on each one just to make sure I knew where the end of each hole is. The other wing is real bad only two holes line up. Rudder and elevon is good to go, just the wings. I have no doubt I can do it, however sh#$ happens sometimes and if for some reason I do mess up I would have to pay for a new wing. Thats my only concern. Besides it's a principle thing. This is not what I paid for, I paid for something to be correct. I understand it's factory defect, it happens. It's what happens from here that really counts. Im not mad or upset, disappointed yes. However it's not the end of the world. Hopefully Aerobeez will help me correct the problem and I will continue to be a supportive loyal customer.
