Yep, this comes from the same guy who built that taxidermied cat quadcopter back in 2012.
This rat, Ratjetoe, was Pepijn’s (13) beloved pet until it died of cancer. He had seen the Orvillecopter at his school and deeply wished it could be like that… We made that dream come true.
Built by Arjen Beltman.
Edit: Holy crap, this dude also built an OstrichCopter, featuring the worlds first flying ostrich!
