I'd appreciate hearing advice on the best visual clues for getting the wings on a Ventus 2c aligned when rigging.

I got a lot of suggestions for easier rigging of my Ventus 2cxm. Thanks, they were all useful.

I also tried cooling the main-pin. I greased it, put it in a plastic ziplock bag, and left it in a cooler with some freeze-blocks for an hour. It was definitely cool to the touch when I took it out, and it did slide in easier.

The air temp was about 70F, and assuming the pin was cooled to 40F, the diameter would be reduced by about 0.4mil (thousandth of inch).
