Why helicopter Cannot fly upside down?
There’s a reason why you should never, ever fly upside down in a helicopter: The rotors will bend toward the skids and cut off the tail and you’ll plummet to your death. Helicopter rotors are designed to handle a lot of flexion, because each blade has to bend up and down as it moves into and against the slipstream.
What kind of helicopter can fly upside down?
Apache AH64D – the only helicopter that can fly upside down.
How can an RC helicopter fly upside down?
Inverted flight requires an RC helicopter with a rotor blade that is symmetrically built to carry the weight and is particularly developed to perform this type of operation. The RC helicopter’s power to weight ratio and collective pitch range must be just right for it to successfully fly upside down.
Why can the Red Bull helicopter fly upside down?
The rotor head, to which the blades are attached, is milled from a solid block of titanium rather than multiple components, skipping the hinges that typically allow the blades to bounce up and down to absorb aerodynamic forces.
How long can a helicopter fly inverted?

Can helicopters fly in heavy rain?
Helicopters generally have no issues flying in rain. Rain does not affect the thrust created by the blades needed for takeoff. However, rain can impact the visibility for the pilot substantially. It is up to the pilot to determine whether or not it is safe to fly.
