9. Assembling the model

Push the hinge pin 41 through the hinge leaves, holding the rod

in a pair of pliers if necessary. Fit the fins 5 and allow them to

snap into the retaining clips. Check the wing folding mechanism.

Ensure that the canopy latch system works properly, and make

any minor adjustments required.

Fig. 16

10. Installing the radio control system

There are two different versions here: glider and electric glider /

glider

a. Glider:

This version requires a receiver battery consisting of four AA-

size NiMH cells in the S or W format. The battery should be

secured with Velcro (hook-and-loop) tape. The Centre of Gravity

can be adjusted within certain limits by re-positioning the battery.

If that is not sufficient, you will need to add a little lead ballast.

Ensure that the receiver battery does not obstruct the canopy

latches 24 + 25 when you try to engage them.

There is space for the receiver in the rear part of the fuselage

cradle. Deploy the aerial in the appropriate channel in the wing.

If you are using 2.4 GHz equipment, there is adequate space for

the aerials towards the front.

Fig. 17

b. Electric glider with glider option:

The flight battery (Li-Batt BX 3/1 - 950, # 15 7118) should be

installed in the front part of the fuselage cradle 20 + 21, where it

is retained with Velcro tape. The Centre of Gravity can be adjusted

within certain limits by re-positioning the battery. If that is not

sufficient, you will need to add a little lead ballast. Ensure that

the receiver battery does not obstruct the canopy latches 24 + 25

when you try to engage them.

The receiver can be located adjacent to the motor, with the aerial

deployed in the appropriate channel in the wing. Install the speed

controller next to the flight battery. If you detect interference when

you carry out a range-check, try swapping the positions of the

speed controller and the receiver.

The electric glider is designed to be powered by our Power Set,

# 33 2654 (45° climb performance) or the Tuning Set, # 33 2655

(vertical climb). These power sets contain everything you need,

but neither is included in the kit. Installing the power system in

the model takes just a few seconds: fold the model apart in the

centre, place the power set inside, fold it closed again, insert the

connector, and the model is ready for launch as a powered

glider.

Fig. 18

If you wish to fly the Xeno electric glider at the slope as a pure

glider, the conversion is carried out as follows:

Open the model, disconnect the motor plug, remove the power

set, fold the model closed again and fit the glider canopy: job

done, time to go gliding. As with the electric version, the flight

battery is used to power the receiver and servos via the speed

controller’s BEC system. No re-trimming is required, as the

power set is located virtually at the Centre of Gravity.

11. Completing the power set

Assemble the power set, referring to the instructions supplied

with it.

Figs. A1 - A6

12. Initial test-run

We assume that all the radio control system components have

been installed and connected as shown in Figs. 17 and 18. Use

the Velcro tape 10 + 11 to secure the components.

Check the neutral position and the travels of the elevons. Check

that the servos rotate in the correct direction relative to the stick

movements, and ensure that the elevons are free-moving. Check

the direction of rotation of the motor, and reverse it if necessary.

13. Settings (guideline only!):

Centre of Gravity: approx. 220 mm (+/- 10 mm)

aft of the fuselage nose

Motor thrustline: pre-set

Control surface travels:

Measured at the widest point of the elevons

Elevons

Aileron travel: 14 mm up / 16 mm down

Elevator travel: 12 mm up / 12 mm down

14. Test-flying:

For the first flight wait for a day with as little breeze as possible.

The early evening is often a good time.

If you are a beginner to model flying we strongly recommend that

you ask an experienced model pilot to help you for the first few

flights, as learning to fly alone is very rarely successful. If you

don’t know any other modellers, ask your local model shop about

flying clubs in the area, and go along to their flying site for help.

Another useful aid for those “first difficult steps” is a flight simulator

on a PC.

You can download a free simulator from the MULTIPLEX website

at www.multiplex-rc.de. An interface lead for your MPX

transmitter can be obtained from any model shop (Order No. # 8

5153).

Be sure to carry out a range-check before the first flight!

Just before the flight, charge up the transmitter battery and the

flight pack using the recommended procedures.

Before you

switch on the transmitter, ensure that “your” channel is not already

in use.

Ask your assistant to walk away from the model, holding the

transmitter. The transmitter aerial should be fitted but completely

collapsed.

Your assistant should operate one of the functions constantly

while you watch the servos. The non-controlled servo should

stay motionless up to a range of about 60 m, while the controlled

one should follow the stick movements smoothly and without

any delay. Please note that this check can only give reliable results

if the radio band is clear of interference, and if no other radio

control transmitters are in use -

even on different channels. If the

range check is successful, repeat it with the

motor running.

There should be no more than a very slight reduction in effective

radio range with the motor turning.

If you are not sure about anything, please don’t risk a flight. Send

the whole system (including battery, switch harness and servos)

to the Service Department of your RC system manufacturer and

ask them to check it.

The first flight ...

Glider:

A hand-launch directly into any breeze, with the wings level and

the nose slightly down, will give you an initial idea whether the

model is correctly trimmed, or whether adjustments are required.

Flying at the slope

Ridge soaring is an extremely attractive form of model flying.

Soaring for hours on end in slope lift, or flying continuous

aerobatics, without needing any outside aid for launching, must

be one of the finest of all modelling experiences.
