SECTION C – ADJUSTMENTS AND ELECTRONIC SETUP
NOTE: The main rotor blades are matched by weight and marked as matched pairs with stickers
A and B in order to distinguish them. Please neither remove the stickers nor the balancing tape
stripes on the rotor blades. Please do not mount the rotor blades before you reach the according
step in the assembly manual. Mount the rotor head and the servo rods as shown in Exhibit A-5.
1) Servo Setup
a) Make sure that all servo levers are mounted so that the servo lever is rectangular to the
servo housing while centered. You might have to power up the servos to determine this
position.
b) For the three cyclic servos, it is important to match that when all three servos are in their
center positions, the swash plate must be leveled and at its 0 degree CP position. This
equals a distance between the lower edge of the swashplate to the upper end of the
servo support of 10.5mm. Depending on the servos you are using, the lengths of the
pushrods might differ slightly from the suggested lengths below: servo to L-lever
51.5mm, L-lever to swashplate 34mm, swashplate to blade grip 61mm, measured ball
link center to center.
c) For the tail servo, make sure that the servo is producing 0 degrees pitch on the tail rotor
blades once in centered position.
2) Test Motor
a) Dismount the rotor blades, if you have mounted them already. Please turn the motor
with your hand and check if the gear meshing between motor pinion and main gear is
appropriate. Make sure that the tail belt is tensioned properly. The main rotor has to spin
counter clockwise if viewed from above the helicopter, the tail rotor blades have to spin
clockwise if the viewed from the left side. Then power up the motor via ESC and verify
that the motor does spin in the proper direction (nothing will happen if it spins in the
wrong direction), eventually correct the direction.
3) Test Gyro / RX Setup
a) In order to test your gyro, please follow your gyros instruction manual. Gyro gain settings
and fine tuning has to be done after the helicopter is installed into the fuselage. Please
be advised that the swash plate is a 140deg and not a 120deg CCPM.
b) If using the Roban 3 axis gyro, please use the following parameters (online)
4) Test TX
a) In order to test your TX and the proper setup, please follow your radio controls user
manual. Fine tuning and trimming can be adjusted once the helicopter is installed into
the fuselage. For now a mere reaction to your control inputs does suffice.
SEKTION C – EINSTELLUNGEN
Hinweis: Die Hauptrotorblätter sind paarweise ausgewogen und jeweils mit A und B
gekennzeichnet, um Sie unterscheiden zu können. Bitte entfernen Sie diese Aufkleber nicht.
Bitte montieren Sie die Rotorblätter nicht, bevor Sie nicht ausdrücklich durch die Anleitung dazu
angewiesen werden. Montieren Sie den Hauptrotorkopf und die Servogestänge zu den
Blatthaltern, wie in Anhang A – 5 dargestellt.
5) Servo Einstellung
a) Stellen Sie sicher, dass der Servohebel rechtwinklig zum Servogehäuse steht, wenn sich
das Servo in der Mittenstellung befindet. Dazu müssen Sie ggf. die Servos mit einem
Signal vom Empfänger versorgen.
b) Es ist wichtig, dass die Taumelscheibe, wenn alle drei zyklischen Servos in Ihrer
Mittenstellung sind, sich im Lot zur Hauptwelle befindet. Darüber hinaus muss Sie sich
