Cardboard RC planes are a popular choice for DIY projects, as it’s a surprisingly simple process that yields pretty awesome results. They need the same four primary controls used to fly an airplane: throttle, elevator, ailerons and rudder. For their victorious flight, the Irishmen used a UAV Brushless Motor A1510 2200Kv, a DEVO 7 – RX 701 transmitter and receiver, a 7.4-volt battery, a propeller, and, of course, a whole lot of cardboard. If you’ve ever tried to build one of these things (or any model kit, really) then you know the process is always a gamble — there are just so many minor glitches could easily ground them. That’s why the duo’s genuinely shocked at their success, and why their glee is so contagious. It’s a feeling to which anyone who’s labored a project can surely relate. And it goes to show you that, despite initial misgivings, father-son projects really can take flight.
