RC helicopters have quite a few differences than passenger and military helicopters, which is why they can fly upside down.

Technically, any gas-powered turbine that makes thrust by expelling hot gases at high speeds qualifies as a jet engine. However, turbojet and turbofan engines generate forward motion. Helicopters ...

In fact, helicopters were preceded by autogyros, which used unpowered rotors that, like windmills, spin and generate lift when the autogyro is moving forward due to the thrust of a propeller.
