Before planky 2.0 there was planky 1.0 ! But i never posted anything as it looks kind of..interesting and i didnt know how it would fly.
So when i first got my hot wire cnc going i was having problems with the software and it would only cut left side correctly and i really wanted to build something that weekend. I figured "hey a straight wing is the same on both sides", so i cut out 2 left cores, slapped a nose and a tail, rummaged around in the paint cans and here we go, planky 1.0. Flies amazingly well, like zero trim out of the hand. I would have swore with that short root that the cg would be a pain. pw1211 airfoil, home depot rigid insulation, some glass spars, laminate, balsa elevons.
