4 Year Old Justin Jee - RC Heli Stick Movement - Sep 2006
4 year old Justin Jee ( http://www.JustinJee.com ) FaceBook (
http://alturl.com/ohzkf ) flies his Raptor 50 heli at the 2006 OC Bob
(Ocean County Bob) Fun-Fly in Atlantic City, NJ. Alan Szabo Sr. (Alan
Szabo's dad) recorded Justin's stick movements while Alan & Danny watching
the flight. This event is the first time that Justin was exposed in
public. After his buddy box fligth with Raptor 50, he went back to sim
doing fig 8's for safety. He then started flying at the field again around
the end of July. So, he has been flying at the field for about 2 months
prior to this video.
Please visit Justin's website at http://www.JustinJee.com for more info and
HD videos. You can also read about how he got started RC in "Story of
Justin Chi". It is located in "About Me" section of his website or click

Here is the stickcam video of Justin 3 years later.
WORLD CHAMPION RC Helicopter pilot Demonstrates his Awesome Skills
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
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.
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
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
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.
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)
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.
Red Bull Helicopter does back flips!
Yes, it does back flips. It is a Eurocopter BO-105 CBS 4 Twin engine
helicopter. Stock model with a Rigid Rotor system, the fixed rotor is why
it can do aerobatics.

Im Alter von nur 59 Jahren verlor die Modell Szene ein Urgestein des
Hubschraubersports. Heinz Hoffmann * 15.09.1954 ist am 06.06.2014
Wir trauern um einen Freund und Fliegerkollegen der mit seiner Ruhe und
seinem Sachverstand vielen Jungpiloten ein Vorbild war und mit diesem Film
auch immer bleiben wird.
Dieses Video war das erste das ich gedreht habe und ist der Grund weshalb
der Modellsport, das Fliegen zu meinem Hobby wurde. Vielen Dank lieber
Heinz. Wir vermissen Dich sehr !
Ruhe in Frieden.
Unsere Gedanken sind bei seiner Familie.
