Remember back in school when we folded up notebook paper and made those little airplanes that we would fly across the room when we thought the teacher was not looking ? For under $25 you can have a remote control paper airplane that you can control with your smartphone ! This looks as simple as connecting the little motor to the paper airplane, and then downloading the app that allows you to control it when it is flying. You can't take pictures like you can with a drone that has a camera mounted on it; but you can have fun flying it around, for sure. https://toysgrabber.com/products/smartphone-controlled-paper-airplane
