I stumbled upon the 'Power Up' plane idea: #-Link-Snipped-# and I think it's very simple enough for you try it on this weekend. If you work on one, do not forget to share the photos and videos with us 😀 . The concept uses a capacitor mounted at the top of the paper-aircraft's nose and a propeller at the back. Single charge gives the propeller a life of about 90 seconds - which is quite impressive for a paper aircraft flight. What say you? Worth trying?

Video shows one such plane in action -
