Here is my spad Primo 40. It is about 6 mo. in the making including the parcial designing, It is cut directly from the Primo plans except the horizontal part of the fuse. I used 6 mil all around with a saito 91 on the nose It tips the scales at just under 5 lbs with a half tank of fuel.

looks great, but more importantly how does it fly?

Thanks, look to maiden it after the weather clears up
