Here are pictures of my stand which is similar to what you have. So what do you do, put the wings on and place the plane on the swivel at the CG point? Pardon my stupidity but I've spent fifteen minutes studying the pictures and still not sure what you are doing. By the way, my stand comes out of the base and the spikes on the bottom are then pushed into the ground at the field to hold the model while it is being cranked.
