OK now I have some time to write a little bit. First, wing pins, these are hidden but they are there. Waht I foung was that if you put the wing tube in and drill in the pin area at the same angle as the tube you will find the socket for the alignment pin. I have now mounted the engine, cowl and canopy. The Saito 180 fits beautifully and with the radio gear and hardware I'm weighing in around 11# pounds dry. SWEEEEEETTT!!!! I put my engine mount on with a piece rubber behind it to absorb some of the vibration. The cowling was mounted simply by using 6-32 nylon screws with a brass inserts in the fuse. I only used six screws total 3 on each side. I drilled into the small tab with the angle stock behind it and put in a brass threaded insert and glued it, I used a simular method with the canopy but I used blind nuts instead and 5 on each side.
