Whimsical Remote Control Flying Balloon Object

Here is a video of Hanetama (lit. “Winged Sphere”), a RC flying balloon object with flapping wings, from Tyoukogatalabo’s (loosely translated as “Micro Flying Object Research Lab”) YouTube channel. He says he used 4 servomechanisms and controlled it with a TARANIS transmitter. He has also uploaded videos of all sorts of other fun flying things, like a cat-shaped ornithopter. (He loves cats.)
