Tiny Whoops, Inductrix FPVs, and NewBeeDrone Acros are great fun. They can be very fast, they're very maneuverable, but they're also a dog and cat magnet. And, if you're racing them through your house, make sure that either the bathroom door is shut or that the toilet lid is down. I've recovered one from a "splashdown", and it forced me to replace motors. Learn from my mistakes.
