Congratulations for the purchase of your Joker -helicopter.
With this model you have a long-life product in your hands, which is maufactured to
the highest quality standards. So flying and servicing will give you a great deal of fun
for a long time.
The manual contains many detailed graphics so that you should have no problems
when bulding the helicopter. Please take a little time to study the manual before
beginning. Then you get an overview of the building process.
The kit contains some hexagon wrenches. Additionaly you need the following tools:
Tools:
socket wreches with grip for nuts 5,5 and 7 mm with a thin outer diameter.
open wrench 4,5/5,5 mm
hexagon wrenches with axial grip 2/2,5/3 mm
hexagon wrench with cross grip 4 mm (2 parts for feathering spindle)
sharp tongs with 45° cranked head
Phillips screwdriver small
screwdriver flat
screw lock (for example Loctite 243 blue)
Special Tools:
ball joint tongs f.e.Robbe S 1360
pitch gauge f.e. Robbe S1366
paddle gauge f.e. Robbe S1368
Lubricants:
axial bearings: normal machine lubricant (from toolmarket)
autorotation coupling: synthetic motor oil
The gear wheels don´t use lubricant.
Recommended RC-equpiment:
receiver: PCM-system with 10bit and double superhet
RC-batttery: 4 cells Sanyo KR 1400AE
swash-plate servos:Futaba S9202 or better
gyro: Futaba GY 401 with servo S9253
interference elimination filter between receiver and controller
If you have problems when building your model please e-mail us. We help you!
And now: Much fun by building your Joker !

Safety rules:
Radio controlled helicopters are not toys. The wrong use of such models can cause
accidents with serious injuries.
Therefore please bear the following rules in mind:
-For engine running tests on your workbench remove the complete mainrotor
including all rods and the tailrotor blades. Make sure that nothing can come
in contact with the tailrotor assembly.
-With an electric helicopter there is a danger of sudden engine starts. So
remove the main-and tailrotor before connecting the battery packs.
-Don´t switch the controller off and on suddenly when running up. Wait some
seconds if retrying.
-In hovering flight please keep a distance of at least 5 metres from the
helicopter.
-When flighing DON’T aim at persons or other creatures and keep a safe
distance of at least 20 metres.
-Don´t fly in forward flight if your battery is nearly empty, if you can´t
autorotate in all situations. For landing calculate a safety reserve of at least
30 seconds or better one minute. Empty the battery while hovering.
-Don´t empty the battery absolutely completely in hovering, otherwise the
battery can be damaged.
-For the first flight a partner should tell you the flight time in intervals of 30
seconds so that you get a feeling for electric flight. After some time you feel
an empty battery by giving full pitch for a moment. When the rotorspeed
shuts down then you should search the ground for landing.
-Practice autorotations with running engine as soon as possible.
-When you see that a crash is unavoidable try to stop the engine before
ground contact.
Liability exclusion:
We can´t check for correct building, adjustment, maintanence and usage.
So no guarantee is possible.
