Notes on recommended accessories:
Electric version with power system / Glider version
The optimum power system for the electric version of the model is the
"LENTUS" brushless power set # 1-01183.
The components of the power set are carefully matched to each other and
fully tested. If you wish to use different batteries, speed controllers, motors
or radio control system components, you do so at your own discretion.
However, if you do this we are unable to provide after-sales service.
Alternatively you may prefer to complete the model as a pure glider. This simply
involves gluing the optional glider nose # 22 4350 to the front of the fuselage.
In this guise the model has a more convincing semi-scale appearance.
The glider version can also be launched by aero-tow if the tow-release
unit # 72 3470 is installed. This is actuated by a length of 1 mm Ø steel
wire running in a 3/2 mm 'snake' sleeve.
Electrical connections to the wing-mounted servos
A ready-made (soldered) cable set terminating in green MPX M6 high-
current connectors is available under Order No. # 1-01286 (or with all
servos: Order No. # 1-01288). The set includes the servo extension leads
and all items required to complete the electrical connections at the fuselage.
The servos are connected automatically when the model is assembled,
i.e. the servo leads connect to the sockets in the fuselage when the wings
are slid into place.
This makes it very easy and quick to assemble the model, and enhances
safety by avoiding the danger of mixing up the connectors.
Optional retractable wheel
The Lentus is prepared for installation of the optional retractable wheel
# 1-01759.
With the retract fitted, the model is capable of scale FES take-off (Front
Electric Self-launch) from the ground using the same motor and speed
controller. However, it requires the 4S battery # 1-01025 and the smaller
8 x 6" propeller # 1-01970.
2. Cutting the stiffening longerons (GRP rod) to length
Use a pair of side-cutters to cut the shorter GRP fuselage stiffener rod
mm Ø x 700 mm) into two pieces of equal 330 mm length (=> 2 x 330 mm).
3. Gluing the fuselage stiffeners in place
This is the procedure: first apply a little Zacki ELAPOR
then press the stiffeners into place using a tool such as a screwdriver.
Now run more Zacki ELAPOR

6. Installing the front fuselage reinforcing tube
The front lower section of the fuselage is reinforced with the rectangular-
section GRP tube
undercarriage well. The optional retractable under-carriage # 1-01759
is fixed to this tube, so it is essential that it is glued very securely to
the foam. Mark the depth to which the tube is inserted into the motor
bulkhead: about 15 mm.
7. Gluing the motor bulkhead to the rectangular tube
Tip: we recommend that you screw the motor (power set # 1-01183) to
the motor bulkhead at this early stage, as it makes handling easier.
Note that the motor cables must be located at bottom right, as seen from the tail.

and the reinforcing tube
shell. Apply glue to one end of the reinforcing tube, push it into the
rectangular opening in the motor bulkhead as far as the marked point, then
- working briskly - press this whole assembly into the right-hand fuselage
shell. Ensure that the tube and the motor bulkhead make full contact with
the foam. Apply a little additional hot-melt adhesive to the transition point
between the rectangular tube and the motor bulkhead. Fig. 5
