The brief was to design a low cost 70mm Parkjet to replace
the popular Flycat, it was to have no frills, look similar and
to have no landing gear. The result is a similar outline to
the original Flycat but it is bigger 1042mm as opposed to
640mm and it has an internal 70mm fan unit rather than an
EDF unit sitting on top. With the addition of fan inlet ducts
and all round streamlining and updated color scheme the
new Flycat looks stunning and it flies as good as it looks.

This version of the Flycat is PNF and comes with a 12
blade 70mm fan unit, high power 3040/2000Kv brushless
motor, 80amp ESC with BEC and 3 9g metal geared
servos. All these items are pre-installed at the factory as
are the colorful decals so time from starting the build to
having it ready to fly is minimal. All you will require is a 4ch
or greater transmitter and receiver and a 6S 30~60C
4000mah lipoly battery with suitable charger.

fuselage side of the tail boom that does not have the cut out in the fin.

7

,

7. Slide the tail boom over the wing root of the fuselage as shown and
glue into place.

8. Prior to gluing the 2nd tail boom into place ensure you

feed the elevator servo extension lead into the cut out slot

in the boom (see following pictures).

9. Apply a small amount of glue into the slot in the wing
root and press the lead into the slot.

10. Do the same along the boom and up to the cut out in the fin.

9

FLYCAT

10. Ensure the elevator servo extension lead connector is

positioned in the area of the cut out in the vertical stabilizer.

11. Apply some slow setting CA or similar glue into the recesses

on both vertical stabilizers where the tailplane slots into as shown.

10

,

12. Slot the tailplane into position and leave for the glue to set.

ensuring the elevator servo lead is positioned correctly as shown

below.

13

FLYCAT

18. Slide the wing assembly fully home onto the plywood

tongues until the fixing screw holes align (see below picture).

14

19. Screw the supplied PK screws through the plastic

wing fixings and into the plywood tongue. Repeat this

whole operation with the other wing.

recess at the rear of the battery compartment.

15

FLYCAT

21. Install a 6S 3000mah lipoly battery into the
battery compartment

C of G should be 510mm ± 5mm from the nose of the

Flycat. As shown this position is in the vicinity of the

rear of the front wing fixing.

the correct balance

---------------------------------------------------------------------------------

The following pictures show the

recommended set-up.

22. Set the aileron travel to 15mm each way and we
recommend you use between 20~30% exponential travel.

23. Set the elevator travel to 30mm each way and we
recommend you use between 20~30% exponential

travel.

Your FLYCAT should now be ready to fly

Flying Tips.
Before you fly please check your controls and make sure you double
check!
Left aileron, the left aileron should go up, right aileron, the right aileron
should go up, back stick and the elevator should go up, forward stick
the elevator should go down. Double check that the model balances on
the C of G correctly, it should balance at the 510mm ± 5mm mark in a
slight nose down attitude..
Now you’re ready to for your first flight, please make sure you do a
range check of your radio equipment first.
The H-King Flycat is a hand launched RC airplane, If you are unsure of
hand launching your plane then please find someone who can assist
with launch. Hold the model underneath and about head high, facing into
wind, check the controls once again then smoothly open the power up to
full. Give the model a good level throw and allow the nose to drop just
slightly so that the plane builds up speed. Being a ducted fan you do not
get the prop wash as you do with a propeller driven plane so you do
require airspeed before you initiate a climb.
Once airborne and safely in the climb carry on to a safe altitude to
adjust your trim to get the Flycat Flying straight and level on about ¾
throttle. If your plane is not flying correctly land and adjust your radio
or the Flycat's linkages where necessary.
Once you have your Flycat flying well it will perform as if it is on rails,
it's fast, smooth and manoeuvrable. You will be able to fly all the usual
jet like aerobatics with ease and it looks really great in the sky.
When it comes to landing line up your plane with the landing area
(hopefully a flat grassed area) using your elevator to control pitch and
speed, throttle to control descent and ailerons to keep the wings level
simply glide the Flycat home. As it's name, it's a real pussycat and will
float into land very easily due to it's low stalling speed.
Your maiden and the sweating is now over, recharge your batteries and
really have fun with the Flycat, your fellow flyers when they see it go
will all want one, hope you have fun with this amazing RC plane from H­King.

Option for fitting retracts.

As shown in the following pictures the foam has been
pre-cut to allow for the installation of retracts. There is
not a bespoke set of retracts made for the Flycat. They
is a good selection on HobbyKing.Com or you may even
have a set in your workshop from a redundant model.

23

FLYCAT

If you do not intend to fit retracts to start with then

we recommend you tack glue the foam blanking

parts into the model. This is so they can be easily

removed at a later date if you wish.
