Select a program for 4 x 90° swashplate
steering. Depending on the R/C-System
one of the servo position is not covered.
It is mostly 0°, so
Aileron, right side is at 90° position
Elevator, rear, is at 180° position
Aileron, left side, is at 270° position
Due to the way of mounting the servos,
the elevator servo has to be reversed.
We strongly recommend the following
values for the first flight attempts:
max. pitch
+9°
hoover- pitch
+5°until +6°
min. pitch
-1° until -2°
Increasing pitch should move the
swashplate straight upwards.
Make sure that the servo travel on these
servos is exactly the same. You may limit
the travel down or upwards. Check the
ultimate swashplate position and reduce
the travel step by step. Adjust for the
same limits on all three servos.
As a general rule, the pitch travel should
increase the tailrotor servo by 30% for
increasing the pitch value, 20% for
decreasing the pitch value. On certain
r/c-systems this value may have to be
reversed. Please check your manual for
details
It is essential for the flying culture that the rotor
blades both move on one track. Mark one blade
with red tape at the tip. You can check the tracking
by operating the helicopter near lifting speed and
watching the moving rotor directly from the side.
If you see 2 blade tip levels, adjustment is
necessary.
If you see the red mark on top, the marked blade
mixer rod should be shortened.
If you see the red mark under the unmarked blade,
the marked blade mixer rod should be enlengthed.
Adjust until you see one level of blade tips only.
Be aware of general safety regulations. Make this
adjustment at the airfield only. Wear eye protectors.
Keep a safety distance of at least 10 ft. Wait until
the rotor comes to a complete stop. Protect the
helicopter against undesired motor start. Work at
the rotor with disconnected battery only.
