What insane thing will Peter Sripol make next? When we last checked in, he attached a flamethrower to a Thomas the Tank Engine mecha. His most recent project was to build a functional model airplane powered with a cordless drill motor.
It was a big challenge. A drill and battery are heavy and the RPM is very low. But Peter's friends tolerated him long enough to make it work. The biggest challenge was getting their CNC mill to correctly cut a wooden propeller. And the end of the project, they ended up with a remarkably maneuverable aircraft.
