Smartphone Controlled Paper Airplane
Control paper airplanes that you make with your own smartphone - by adding an engine to it!
The Power-up 3.0 engine makes your self-made paper airplane a REMOTE CONTROLLED PAPER AIRPLANE! How cool. And the Power 3.0 engine is fully rechargeable via USB with a lithium battery.
This thing started as a Kickstarter project but was recently successfully funded and you can buy it.
