Assembly manual:
You will need these accessories:
- 4x Futaba S3150 for Ailerons and Flaps
- 2x Graupner DS3728 for V-Tail (or Graupner DS3781)
- 4cells Sanyo RC-2/3SC (1200mAh, Ni-Cd)
- Receiver (min. 6ch)
Wing:
Solder together the cables and MPX connectors for wing servos. We recommend
don’t use any soldering fluid. Use for each wire isolation.
Glue the servo holders into the wing (5min Epoxy).
Put together the servo with servo arm and third ball bearing. For ailerons use 6mm
servo arm and for flaps 8mm servo arm.
Connect the servo with the extension cables and make some safety lock at the
connectors (insulating tube).

Install the servo into the servo holder.
Put two small trust plates to the servo holder.
Bolt the trust plates with four small screws.
Put together the linkage for ailerons and flaps. Two M3 metal clevises and M3 screw
rod. The metal clevis at ailerons servo must be modified (see the picture).
After completing, set-up and trimming glue the clevises with Loctite or CA glue.
Put the servo covers over the servo holes and glue them with Tesa tape.

Fuselage and V-tail:
Glue into the fuselage servo holder for V-Tail servos.
Install the servos. Use 8mm servo arms.
Put together the V-Tail linkage. Abrade (about 50mm) the 2mm wires before you
glue them into the carbon tubes (better stability).
Glue the balls (from ball pivot) with Loctite onto V-Tail horn wire.
Put together the fuselage and V-Tail.
Connect linkage with servo and V-Tail.

Put into the fuselage the linkage leading. Put trough the fuselage wire for antenna
before this operation.
Take away the V-Tail from fuselage.
Make a antenna extension from 0,3-0,8mm wire (1m) and plastic tube (1m). Bend
the plastic tube with the wire to this form (see the picture).
Solder the antenna extension with antenna wire in fuselage.
Complete the V-Tail and fuselage.
Glue into the fuselage the connectors for wing cable extensions.
Use this battery pack form.

Glue into the fuselage (nose) about 40-60g lead to make recommended C.G.
C.G.: 110-112mm
Towing hook: 108-110mm
