Has anyone explored the idea of taking the hardware from a mini and building it in to a lightweight carbon fibre frame? Would it be very easy to make a frame that's lighter than the stock mini? I know the stock shell is pretty light, but if you dispense with the folding arms and go for rigid ones there's surely a good few grams to be saved there? I guess the ultimate goal here would be to make the mini a little bit more nimble and boost the flight time a bit, but primarily just have some fun making a frankenmini?
