I don't design planes, i just build them, some never get flown, i just like to build, for example on rcgroups there is a full former Sbach fuse with kfm wings. Although this is a great looking build it was extremely tedious to build and hand cutting skins to transfer to foam board and getting it to bond to formers was a pain. What i'm trying to convey is never go that route, stick with posterboard. The Moth will get flown though.
