no because otherwise it would come crashing down to the ground and everyone would DIE
The answer to this is not as clear as you'd think.... They certainly can not invert and fly along. However certain designs can do rolls where the helicopter momentarily inverts. One of the first helicopters to acheive this was the Lynx.
yes they can.
How far can helicopter fly on a one tank of gas
DOES a poo
to fly
No
Depends on the purpose and make of the helicopter.
It depends what you mean by the term 'ultralight' ! If you mean a scale model of a helicopter that you fly by remote control - no. If you mean a full-size helicopter you actually sit in to fly - yes.
A helicopter can only fly in an atmosphere, where there is something for the rotors to push against. There's no atmosphere on the moon, so a helicopter can't fly there.
The helicopter might not fly because the battery is dead and needs to be charged or because you have the remote and helicopter on different frequencies.
No. A helicopter is not faster than an airplane. A helicopter could fly at about 400-650 kph. But a plane could fly much faster than that.
