My first foray into DLGs, the scratchbuilt "Electron" is a 100g foamboard glider weighing 100g. The wing and tail surfaces are made of de-papered and taped ReadiBoard (aka Dollar Tree foamboard) affixed to a 6mm carbon fiber tube from Radical RC. The electronics are minimalist and not yet enclosed. The wing was provisionally mounted with 3M extreme mounting tape with the knowledge that I would crash, allowing the wing to pop off. I was aware that at some point it would detach upon launch, and it it did. After some strengthening it ought to be better able to withstand launching forces.
