It depends on the Helicopter. Small ones like the homebuilt mosquito can only lift a few hundred pounds, but large commercial ships like the Russian Mi26 can lift 80,000 pounds (wich is the same as a fully loaded semi-truck)
as my experience mostly flight time for rc helicopter is 3-5 mins. and need a rest for 15mins as the motor get hot.
The rotors are used for lift and thrust on a helicopter.
That depends on type of helicopter
the difference between an helicopter creating lift and an airplane creating lift is simple. an airplane creates lift by moving forward and its wing that has an aerofoil shaped will create lift. this gives the lift for the airplane and to fly. for helicopters, instead of the aerofoil is fix like an airplane, the aerofoil wing is rotating and create lift. that is why the helicopter does not need to move forward to gain momentum to create lift. by rotating the aerofoil (the blade) the helicopter can creates enough lift to lift up the helicopter.and that's how it fly..
Spinning wings create lift to make helicopter fly.
Lift, thrust, drag, and gravity affects all flying objects and wildlife. The blades of the helicopter provide lift, drag and thrust.
3,000,000 cents
It produces lift and thrust in different ways.
The rotor blades relieve the air pressure from the helicopter forcing it to lift.
helilift
helilift
The same force as the weight of the helicopter and its crew and cargo.
It can lift up to 20,000 lbs or 9000 kilos.
