Rotor blades
The answers; 1. They all have drones and predators. 2. Humans can be allergic to all of them. 3. All 3 have types which can make honey, although wasp honey is not consumed by humans.
Drone can fly without getting detected. Drones kill more people than cancer.
When a new queen emerges from the pupal cell she will spend a few days in the hive, then after usually a week to ten days after emerging, on a fine, warm day she will leave the hive on a mating flight. She will usually fly at about ten metres above the ground towards an area where drones from the surrounding area congregate. The drones will start to pursue the queen at which point she will fly at an increasing altitude with the drones chasing her. Eventually she will be mated on the wing by several drones. After this she will return to the hive and will start laying eggs a couple of days later.As a side point, we know about the drone congregation areas, but although successive generations tend to use the same areas we don't know why the drones choose these particular places to gather.
It depends what insect you are talking about because not all insects fly at the same paste.
The rotating blades form an air screw and screws itself into or out of the air.
To meet a growing demand for commercial pilots to fly small, remote-controlled aircraft, or drones.
no it is not same
A rotocopter spins by utilizing a motor to rotate the blades around a central axis. The motor powers the rotation of the blades, creating lift and allowing the rotocopter to fly. The pitch of the blades can also be adjusted to control the direction and speed of the spin.
When you press Y, your helicoptor blades will start spinning. Now you will be in the air momentarily. To steer, click in the direction you want the helicoptor blades to face. This will fly you in the direction you desire. Once you're done flying, press X over a surface to land.
Birds, airplanes, helicopters, kites, hot air balloons, drones, bats, butterflies, eagles, dragonflies, bees, and pterosaurs are all examples of things that can fly.
A helicopter is able to fly because of the lift generated by its rotor blades as they rotate. The rotor blades create a pressure difference between the top and bottom surfaces, allowing the helicopter to overcome gravity and stay airborne. By changing the pitch or angle of the rotor blades, the pilot can control the helicopter's direction and altitude.
