A couple of videos showing tests of a new bungee launcher from HK (at Kambah Oval no. 3). My son Sam recorded the video using his new Bugs 2SE drone. Printed the tow hooks on my 3D printer, and tried the launches on some easy to fly planes. All went well. Now to try it on some more tricky planes, like the 3D printed Northern Pike.
