Any have any homebuilt planes that use hot wired cores?
I built a home buiilt car of my own design, and a Dragonfly homebuilt canard aircraft (see below) so I am know how to do it. Just wanted to know any existing designs/plans that are good. I would love the build a Dragonfly RC!!!!

Model size, everyone kinda uses a laser cutter, haven't heard of hotwire here in a while, might be a couple of members building scale that do it. That's one of the plus points of foamboard, no trick tools other than a realy sharp knife blade and straight edge.

Nice dragonfly.
