H-KING A-1 Sky Raider
H-KING
The H-King A-1 Skyraider PnF is a realistic flying model of the original plane. It is made of
strong EPO foam and is electric-powered which makes it ideal as a park flier. The 800mm
wingspan size of the plane will allow you to easily transport it in your car without removing the
wings.
The Douglas A-1 Skyraider came too late to see action in WW2, introduced in 1946, but proved
its worth as an outstanding ground attack aircraft in both the Korean and Vietnam conflicts. It
was able to deliver a formidable punch and withstand a considerable amount of battle damage
and still get home. The Skyraider had an impressive service record until being eventually
replaced by the A-10 as the US forces principal ground-attack aircraft.

SAFETY INSTRUCTIONS
1. Please read this manual carefully and follow the instructions
before you use this product.
2. This airplane is not a toy but due to having installed the ORX
stabilization system it is suitable for pilots with low experience.
However, if you do fall into this category then we recommend you
enlist the help of an experienced R/C pilot to give you a hand with
the initial flights.
3. Not recommended for children under 14 years old.
4. Please set up this plane according to the instructions and make
sure you keep your hands and other parts of your body out of the
way of the rotating propeller at all times. Failure to do so will result
in damage to yourself and to the airplane.
5. Do not fly in thunderstorms, strong winds or wet weather.
6. Never fly R/C planes where there are overhead power lines,
automobiles, airports, railway lines or near a highway.
7. Never fly R/C planes where there are crowds of people or over
organised games. This airplane requires a very flat landing and
take-off area that is clear of tree's and other obstacles. Remember
safety is the responsibility of the pilot.
8. Do not attempt to catch the plane when you are flying it.
9. The operator will bear the full responsibility of flying and the
proper operation and usage of this model. We at Hobbyking will not
be responsible for any liability or loss due to improper use of this
model.

the auxiliary oil tanks are handed, they are marked "L" and "R" so please

Center of Gravity: This is between 55-62mm from the wing leading edge. For initial flights
have the C of G nearer the forward mark to improve the stability in pitch. As you get used
to the model you can move it back a little to make it more aerobatic if you wish.
Suggested Control Throws:
Ailerons: 8mm each way (measured at the inboard end of aileron).
Elevator: 10mm each way (measured next to fuselage).
Rudder: 12mm each way.
ESC:
This has been pre-set at the factory and does not require any programming. Switch the
transmitter on first and close the throttle and move the trim to fully down. Connect the
flight battery in the airplane and you will get a series of beeps, once these have finished
the ESC is armed and ready to go.
ORX 6 Axis Stabilization System:
You will also notice when connecting the flight battery the control surfaces will move.
This is caused by the stabilization system going through a system set up, this is perfectly
normal. With the stabilizer unit connected to a spare 2 way switched channel on your
transmitter you can select either beginner or advanced mode.
