Great demo by world champion rc helicopter pilot Radio-controlled helicopters (also RC helicopters) are model aircraft which are distinct from RC airplanes because of the differences in construction, aerodynamics, and flight training. Several basic designs of RC helicopters exist, of which some (such as those with collective pitch control) are more maneuverable than others. The more maneuverable designs are often harder to fly, but benefit from greater aerobatic capabilities.
Flight controls allow pilots to control the collective (or throttle, on fixed pitch helicopters), the cyclic controls (pitch and roll), and the tail rotor (yaw). Controlling these in unison enables the helicopter to perform the same maneuvers as full-sized helicopters, such as hovering and backwards flight, and many that full-sized helicopters cannot, such as inverted flight (where collective pitch control provides negative blade pitch to hold heli up inverted, and pitch/yaw controls must be reversed by pilot).
The various helicopter controls are effected by means of small servo motors, commonly known as servos. A piezoelectric gyroscope sensor is typically used on the tail rotor (yaw) control to counter wind- and torque-reaction-induced tail movement. Most newer helicopters have gyro-stabilization on the other 2 axes of rotation (pitch and roll) as well. Such 3-axis gyro is typically called a flybarless controller, so-called because it eliminates the need for a flybar.
The engines typically used to be methanol-powered two-stroke motors, but electric brushless motors combined with a high-performance lithium polymer battery (LiPo) are now more common and provide improved efficiency, performance and lifespan compared to brushed motors, while decreasing prices bring them within reach of hobbyists. Gasoline and jet turbine engines are also used.[1]
Just like full sized helicopters, model helicopter rotors turn at high speeds and can cause severe injuries. Several deaths have occurred as recently as 2013.
Types of R/C helicopters[edit]
Common power sources of R/C helicopters are glow fuel (also called nitro fuel, nitromethane-methanol), electric batteries, gasoline (petrol) and turbine engines. For the first 40 years, glow fuel helicopters were the most common type produced. However, in the last 10 years, electric powered helicopters have matured to a point where power and flight times have equaled glow fuel helicopters.
There have been two main types of systems to control the main rotors, mechanical mixing and cyclic/collective pitch mixing (CCPM). Most earlier helicopters used mechanical mixing. Today, nearly all R/C helicopter use CCPM.
Practical electric helicopters are a recent development but have rapidly developed and become more common, overtaking glow fuel helicopters in common use. Turbine helicopters are also increasing in popularity, although the high cost puts them out of reach of most people.
Electric
Two small electric helicopters emerged in the mid-1990s. These were the Kalt Whisper and the Kyosho EP Concept, flying on 7–8 × 1.2 Ah NiCad batteries with brushed motors. However, the 540-sized brushed-motors were on the limit of current draw, often 20–25 amps on the more powerful motors, hence brush and commutator problems were common.
Recent advancements in battery technology are making electric flying more feasible in terms of flying time. Lithium polymer (LiPo) batteries are able to provide the high current required for high performance aerobatics while still remaining very light. Typical flight times are 4–12 minutes depending on the flying style and battery capacity.
In the past electric helicopters were used mainly indoors due to the small size and lack of fumes. Larger electric helicopters suitable for outdoor flight and advanced aerobatics have become a reality over the last few years and have become very popular. Their quietness has made them very popular for flying sites close to residential areas and in places such as Germany where there are strict noise restrictions. Nitro helicopters have also been converted to electric power by commercial and homemade kits.
The smallest remote-controlled production model helicopter made (Guinness World Records 2006) is the Picooz Extreme MX-1 sold at many toy stores (although this is infrared controlled, not radio), electronics stores and internet stores, costing about $30 (£28). The next smallest is the standard Picooz helicopter.
Several models are in contention for the title of the smallest non-production remote-controlled helicopter, including the Pixelito family of micro helicopters, the Proxflyer family, and the Micro flying robot.
Glow fuel (nitro fuel)[edit]
Glow fuel, or nitro fuel helicopters (not to be confused with gas, or gasoline powered helicopters) have been made in several sizes over the years. These are referred to as the “class” of the helicopter. They include 1/2A class, 15 class, 30 class, 50 class, 60 class and 90 class.

Apart from being pure awesomeness, it look scary as hell to be next to.
wow. ridiculous the level of control he has on this.
that would be awesome if that could be done but unfortunately that is
impossible defying newtons laws of physics
Хм,охренеть..!
http://youtu.be/l5FqYiZb_5s
Meeega geil 😀 der hats voll drauf
Mad skills, oh wait I misspelled CGI, still neat
Damn that rc can be cut all grass at my backyard
Perfect Control, only this Video is just very Old 🙂 and the Original is on
Tareq’s Channel LoL, hope you don’t try this with my Videos i Report all
you have Lucky i know Tareq and he Like it.
Absolutely awesome!
Great skills + raw power on the Heli!
Хм,охренеть..!
Why does this remind me of a flying insect?
fantastic control, this is far from fake also..its possible because of the
weight and catlike reactions of its pilot
i have no word for this …this is super awsome!!!!!!!wat a controle over
the chopper……a nice thing would be to use lights or glow in the dark
propellar blades…………….
Who ever says it’s fake is d a f
Hillarious! I didnt know helicopters can break dance.
Ахре…ть…..!!!the best…fackin mashine..cool…
I am in awe! Mad skills!
One of the baddest in the game.
So fake hahaha
how dafuq you do that… luls
holy cow, this is crazy!!!! I’m stunned.
I wanna buy this heli. How much it costs?
Awesome skills. Makes one very scared for drones though… (computers can
fly these with even faster coordination soon)
For all of the doubters – look up “Collective Pitch” – the blades on a
collective pitch helictopter can be rotated to change their angle to
reverse the airflow,
any idea the range this can operate?? Awesome
AWESOME!!! Kinda like a man beating a computer at chess!
could slice a head off wow

What helicopter is that? And how does he have enough control to fly upside
down?! This ugh is amazing
Where was this filmed, the location seems to be familiar to me but I cannot
quite remember where exactly…
Wat.
Flash back to the first time I saw my ex shave her kooka
Хм,охренеть..!
What this is amazing WOW
I want to believe it’s real but the shadows don’t seem to be correct
HOW does it hover sideways?
Really Awesome!
Amazing applicable physics!!
Epic fake.
Very nice and solid 3D !
Unbelievable, its beautiful..
this is amazing remember kids practice makes epicness just look at this.
Amazing #goals I can’t believe someone thought it was fake hahahaha
i wouldn’t want to be that close to that thing. looks dangerous as hell.
Most entertaining Smack Down I’ve seen in a while.
Looks like a retarded dragonfly.
This level of skill is insane. its like the helicopter is part of him, no
matter what direction he’s in he doesn’t panic and always keeps it in
control. I would kill myself or someone else trying to do this with a
helicopter like that.
That was awesome guys.
the thing looks possessed.
