How
high does an rc helicopter fly?
The highest i've ever heard of anyone flying one is around 5,000 feet above sea level.
The typical range of the transmitter is 1 mile (line of sight distance).
Your radius of flight within that mile however is limited by your vision (if you can't see
it you can't really control it).
Usually you will be flying within 200 ft from where you're operating.
What if I lose
engine power while flying, will I crash?
There is a small range of height above ground (up around 10 feet off the ground) where you
may not be able to land the helicopter safely if you lose power.
Below this height you should be able to set the heli down safely without the rotor speed
bleeding off too quickly.
Above that height you shoud be able to autorotate, and then set the helicopter down
safely.
In that small "death" window the speed in the rotor will bleed off too quickly,
and the helicopter will be too low to autorotate.
Which would result in a 'hard' landing.
What is
autorotation?
Autorotation is when the helicopter rotor blades are driven by wind power as opposed to
being driven by engine power. In the event of an engine failure the collective pitch
of the main rotor blades can be lowered enabling them to be driven by the air. As
the helicopter falls the wind drives the rotor blades fast enough to provide enough speed
(momentum) for a safe landing when the collective blade pitch is again increased.
