RE: Your best building blunders! ...post em' here.
Oh this could hurt!
I had a nice set of plans for a Panic Bipe a nice aerobatic light weight "Magic" like stunt bipe. Good plane.
But we were on a SPAD kick and Yep I Spadded it out. It looked really cool. Flew like a lead sled. We flew it three times that day then I took it home and dismantled it that night.
