Introduction
Product Introduction
NE R/C 776B is a good-sized glider designed by Nine Eagles Company latest, whose wing span is up to
2008mm. You only need to assemble the aerofoil and horizontal tail before starting to fly.
The transmitter adopts standard 6CH computer intelligent device that makes the pilots to set any function
according their own needs besides the function of mix-control of wing flap and aileron. Independent steering
engine equipment makes it easy to install and maintain. It has good flight performance, strong motivation, 40%
power can make it fly while full power makes it climb vertically. Although it is a glider, it can also complete the
action of somersaults、roll、and inverted flight, which highlights its good control performance. The flight time is
more than 30 minutes through the high magnification and high capacity battery. Gliding in the sky for a long time
makes you enjoy flying absolutely.

2.5 Install another airfoil in this similar process and make sure that airfoil in both sides are inserted into
fuselage completely and servo lead is connected correct.
1. Pull upward and open the aircraft window cover.
2. Turn on the transmitter and confirm the throttle lever is to the bottom before turning on the power,and then
connect the speed controller to it.

3. Switch on the power; you will hear "do re me” voice, indicating connection is normal.
Control transmitter’s each channel at this time, the plane will work. Note: Close the aircraft
window cover before flying and disconnect the power and remove the battery if not fly.
4. Put the battery to specified position and fix it firmly with Velcro.
Flight detection
1. The centre-of-gravity position is very important, but it doesn’t affect flight. The centre-of-gravity position of
this plane is at about 65~70mm leading end of wing and it can be adjusted by moving battery if any deviation.
65-70mm
2. When turns on the transmitter, all spin buttons are in the middle, throttle lever is on the bottom, control
surface of aileron is horizontal, while control surface of empennage and vertical tail is in the middle. And they
can all be adjusted by pushing or pulling adjustable connectors of push-pull wire to make the control surface be
placed in the middle.
3. There are several hole sites in the control surface, connect the push-pull wire to the site, the
plane is weak sense and flying gently. Move push-pull wire inward to hole site in turn, range of oscillation of
control surface will be increased and the weak sense of plane will also become higher in turn.
4. 4CH is Standard Features of this plane, but you can add a function of wing flap according your own demand
and there are 2 wing flap mix-control extended lines inside the packing box. Or you can choose the allocation
more than 4CH before leaving factory.
5. This plane has braking function, pull-down throttle lever rapidly can brake while flight. The motor stops
turning rapidly and the paddle becomes folded at that time. Lower down the throttle slowly cannot brake the
plane.

Introduction of wing flap function
Range of oscillation
of wing flap downward
1.First you should use computerized control equipment more than 6ch.
2.Connect the steering engine extended line (mongline) to 1ch and 6ch of transmitter respectively.
3.Conduct mix-control of 1ch and 6ch on the transmitter, 1ch is for aileron and 6ch is for wing flap.
4.The transmitter should be set on Toggle Switch, because wing flap can just in the middle or sway downward.
5.The distance of travel should be set at 80% generally, the range of oscillation downward should be
15~18mm。
Flying the sky Climber
The Sky Climber is in the configuration of a standard trainer The Sky Climber is easy to fly even for pilots with
moderate experience. If you have not previously flown a trainer it is strongly suggested that you learn to fly with
the assistance of an experienced pilot to help you with the first few flights.
Find a Suitable Flying Site
Find a flying site clear of buildings, trees, power lines and other obstructions. Until you know how much area will
be required and have mastered flying your Sky Climber, a site at least the size of two or three football fields
should be adequate—a flying field specifically intended for R/C planes is best. Don’t fly within six miles of R/C
flying fields and never fly near people—especially children who can wander unpredictably.
Take Off
Until you have become comfortable with flying your Sky Climber, do not fly if the wind speed is greater than 10
mph [16 kilomoters/hr].One final check before take off: always double-check the flight control response to your
inputs from the transmitter before every flight.Be certain the ailerons, elevator and rudder respond correctly and
that none of the controls have inadvertently become reversed.If the surface is smooth (such as pavement or
blacktop) the Sky Climber can take off from the ground.but most grass is probably too tall, so if flying from grass
the model will have to be hand launched.
Hand-Launch
Until you have become efficient at flying your Sky Climber, always use an assistant to hand-launch your model.
Have your assistant hold the model by the bottom of the fuselage. When both of you have signaled “ready,”
advance the throttle to full power. Your assistant should run a few steps with the plane held high above his head,
and then give the model a swift, but controlled toss at a level, or slightly nose-up

attitude. Initially, the model will gently ascend, but within a few seconds it will reach enough speed to climb.
Gently add “up” elevator to establish the climb. Once you have reached a safe flying speed at a comfortable
altitude (approximately 50’[15m]), work the controls as necessary to establish a gentle turn away from the
runway.
Flying
One thing to remember is that, when the plane is flying away from you, moving the aileron stick to the right will
make the plane bank to your right. However, when the model is flying toward you, moving the aileron stick to the
right will make the plane move to your left. Of course, the plane is still responding the same way, it’s just that
your orientation has reversed. This must be kept in mind while learning to fly (and is also a good reason to take
flight lessons from an experienced pilot!).
To establish a turn, “up” elevator (pulling back on the stick) is usually required along with aileron input to get the
model into a bank. To stop the turn, apply a small amount of opposite aileron.
Once you get the plane into the air and have climbed to a comfortable altitude, the first “order of business” will
be to “trim” the model for straight-and-level flight. The model flies best at approximately 3/4-throttle. Adjust the
trims on the transmitter to make minor control surface adjustments as necessary until the plane will fly straight
without any control inputs. Often, your assistant can reach over and adjust the trims for you.
Remember to keep the model high enough to give yourself time to make corrections, but don't let it get too far
away. Otherwise, it will be difficult to detect its attitude and which way it is going.
One final check before landing: see how the model will react when it's time to land and you cut the power. To do
this, while still at altitude, cut the motor power. The model should establish a gentle, downward glide path. This
is how the model will react when it's actually time to land. Add power and
climb back up to your original altitude. Try again, this time adding flaps. To climb, add throttle and immediately
take the flaps back out.Practice a few of these "climb and glides" to judge how far out you will need to be when
its time to land.
Landing
To land, fly down-wind past the landing area. Gently turn into the wind, add flaps and reduce the throttle so that
the airplane initiates an ascending glide path. If necessary, add power to extend the glide path to reach the
runway. As the model approaches and loses altitude, gradually and proportionally add "up"elevator to control
the glide path and altitude. Continue to apply elevator until the model touches down at which time you should be
holding full, or nearly full up elevator. This will cause the airplane to slow and settle to the ground. later, once
you have become more experienced with your Sky Climber, you can cruise around and perform slow “fly-bys”
with the flaps extended.
CAUTION: If, during a rough landing, the propeller becomes jammed and cannot rotate, the
battery and speed control will become very hot if you attempt to add power. Immediately
move the throttle down to stop the motor. If you fail to do this, the motor, speed control and/or
battery will be damaged.
After Flight
Disconnect the battery and remove it from the airplane.Then, turn off the transmitter. Allow the battery to cool
before recharging, or allow the motor to cool before installing another battery for the next flight.Inspect the
airplane to make sure nothing has become loose or damaged.
