Hi. I am building my first rocket in over ten years and am having some problems. According to the instructions I was supposed to have pushed the adapter ring to the 1" mark. I was not quite able to get it to that mark (about 1/16" away from it). On the net step I was supposed to have pushed a tube coupler 1/2 inch into a slotted body tube. Again I was not quite able to align the tube exactly according to the instructions. I am hoping I did not completely ruin this model to the point where I will not be able to fly it. It is straight. Apparently they don't make this model anymore.
