ROBBE Spirit M-8 Instrucciones De Montaje Y Manejo página 40

- Wrap rubber bands No. 9107 and 9112 round the battery
for additional security.
- Bundle together the wires to form a loom, and secure them
using the cable ties 5036 supplied.
- In the interests of clarity the aerial is not shown.
Stage 10
10 Finishing and installing the cabin
- Drill 5 mm Ø holes in the cabin at the points marked „X".
- Trim the rear part of the cabin flange as shown.
- Mask out the glazed area of the cabin before applying the
external painted finish.
- Lightly sand the areas to be painted, and sand the edges
of the cabin smooth.
- When painting is complete cut out the decals and apply
them, referring to the title page of the instructions.
- Press the rubber grommets S5199 into the 5 mm Ø holes
and place the cabin on the cabin holders.
Stage 11
11.1 Completing the main rotor blades
- Lightly sand the main rotor blades S5077 overall using
600-grit abrasive paper, and paint both ends to prevent
moisture absorption.
- Cover the main rotor blades using the self-adhesive film
supplied (see sketches 1-9). The film must be completely
smooth, with no trapped air bubbles or creases.
- Since the blades are made of a natural material (wood)
they may differ in weight and weight distribution even
though they appear identical. Our rotor blades are mat-
ched for weight at the factory, but they should still be
checked for fine balance.
11.2 Balancing the rotor blades
- Press the blade bushes S5098 and S5099 in the root holes
of the main rotor blades S5077. Apply ropoxi to the blade
guides S5098 and S5099 for additional security.
- Screw the rotor blades together through the pivot holes as
shown, using a screw S0031 and a nut S0012.
Assembly instructions
Spirit M-8
- Support the rotor blade assembly at the centre.
- The lighter blade will now rise; apply a piece of the colou-
red tape (supplied) to the lighter tip and add more or less
tape until the rotor blades balance exactly level.
11.3 Installing the main rotor blades
- Attach the rotor blades to the blade holders S50761 using
the screws S0031 and self-locking nuts S0012.
- Tighten the screws S0031 just to the point where the rotor
blades are still free to swivel in the blade holders.
- When transporting the model please note: fold the main
rotor blades back parallel to each other - don't lay them
one on top of the other.
The Centre of Gravity
- The CG should be at the front edge of the main rotor shaft.
Adjust the position of the flight battery until the CG is cor-
rect.
Setting up the radio control system
Basic requirement:
You need a radio control system designed for helicopter use.
Check that the servos are connected to the receiver in the
sequence described in the operating instructions.
Procedure:
- Switch on the transmitter
- Select a vacant model memory
- Program the model memory to the „Heli" mixer type
- Set the swashplate mode to „HR 3"
- Activate the tail rotor mixer (Revo-Mix) if required by the
gyro you are using
- Program the system for a right-hand rotation main rotor
- Set all transmitter sticks and trims to centre
- Do not set up any trim memories or freely programmable
mixers
- Program throttle trim to idle trim (ATL - throttle trim active
only at idle end of range)
- Switch on the receiving system (connect flight battery to
speed controller).

Setting up the servos for collective pitch
- Check the travels and directions of the servos.
- Move the collective pitch stick in the direction of collective
pitch maximum: all 3 servos mounted below the swash-
plate should now move in the same direction and through
the same distance, thereby raising the swashplate evenly,
without tilting it at all.
Setting up the servos for roll and pitch-axis movements
- Note: with an HR3 swashplate linkage the swashplate tilt
corresponds to the helicopter's direction of flight.
- Check the direction of travel of the servos.
- Apply a roll command to the right: the swashplate
should tilt to the right as seen from the tail of the model.
- Use the servo reverse facility on your transmitter if any of
the servos moves in the wrong direction.
- Apply a forward pitch (forward cyclic) command: the
swashplate should tilt forward.
- Use the servo reverse facility on your transmitter if any of
the servos moves in the wrong direction.
Setting up the tail rotor servo
Note:
Fold the tail rotor blades together as shown in the drawing.
When you move the tail rotor stick to the right, the tip of the
top blade should also move to the right (towards the tail
boom).
- Reverse the tail rotor servo if necessary.
Checking the direction of gyro effect (fig.)
Set the gyro to maximum gain.
Swing the tail boom briskly to the right (i.e. the helicopter's
nose moves to the left).
With the tail rotor blades still folded together, the tip of the
top blade should now move towards the tail boom („Re" in
the drawing).
Order No.
