MANUAL

This manual has been compiled to provide pilots
and instructors with information contributing to the
safe and efficient operation of this paratrike. Apart
from important statutory information, this manual
also contains additional information provided by the
motor paraglider manufacturer.
To fly this air vehicle, you need to have the pilot’s
licence for motor paragliders. In addition, it is only
permitted to start and land at approved landing
places. Flights outside the uncontrolled flight space
require a permit, which is mostly requested and
granted via radio.
Further legal requirements such as taking out third
party liability insurance have to be observed. The
pilot has to acquaint himself with the particular
properties and peculiarities of the motor paraglider
prior to starting a flight.
It is compulsory to read the manuals and operating
instructions and to become acquainted with motor,
equipment and all other particulars. It is not permitted
to perform air acrobatics with this motor paraglider.
The legal basis for the operation of ultralight para-
gliders is governed by air traffic laws. Particulars
may be gathered from the associated ordinances.
The provisions and requirements contained therein
have to be observed during operation. The Snap has
been designed, constructed, tested and approved
in accordance with the airworthiness requirements
for motor paragliders. The DULV (German Ultralight
Flight Association) is responsible in this respect.
PRECAUTIONS
Read the flight safety messages in the different
publications, for instance:
Aviation journals
Aviator pocket diaries
News for aeronauts (NfLf)
Federal Aviation Office (LBA) and Federal
Office for Flight Safety (BFS) communications, etc.
Do not carry out any flights during turbulent weather
conditions as a paraglider in principle only obtains
its shape because of its internal pressure. This
internal pressure can only be maintained during
normal oncoming flow conditions.
Exercise particular caution in case there is a
thunderstorm tendency. At any rate, avoid to fly too
close to the storm front to prevent being sucked
into the cloud. In case of emergency, carry out an
off-field landing. Obtain information about low level
flight zones of military aircraft and avoid these.

The back pad is also held by means of a Velcro®fastener that
is folded over the top and bottom frame bracing.
Velcro®fasteners are also used to fasten the back pad
laterally on the frame.

This special back pad prevents the motor from twisting too
badly on the pilot’s back due to the high torsional force
generated by the motor.
The photo on the right shows the vehicle tool kit provided that
can be used to perform the most important operations on the
motor.

The motor is supplied with 2 tank lids. The one with the vent
hole is intended to be used for flying, while the closed lid is
to be used for transport. Prior to a flight it has to be ensured
that the vent lid has been screwed on, or else the motor will
go out after a short flying time. This is because a vacuum is
generated and the fuel flow is stopped.
From the tank, the fuel is channelled to the petrol filter via the
angled outlet (to be checked before every flight).
FUEL AND OIL

SNAP
MANUAL
After that, the fuel is taken through the ball pump and to the
…
… fuel tap and finally to the carburettor.
The engine runs with a fuel-oil mix of 1:50
(2 % Castrol RS2T with 95 octan gas).

The diaphragm carburettor has no special choke system.
However, a cold motor requires more fuel. To facilitate the
starting process, press the ball pump with one hand for
approx. 1 second. This causes the fuel to be channelled to
the carburettor. The ball pump is located underneath the
tank. At the same time, you need to press the pin (No. 3 on the
carburettor illustration on page 10) on the carburettor.
STARTING THE MOTOR
10
SNAP
MANUAL
Now you should take the motor on your back and reach for
the starter handle on the top right. While doing so, hold the
gas handle in your hand. The motor can now be started with
a firm pull.
As a rule, the motor is started with gas. If the motor does not
start, the process with the ball pump should be repeated. If
the motor has been flooded, it must be started at full throttle.
Caution. The motor may never be started on the ground! There
is a high risk of injury!
ball pump

2 adjusting screws are available to adjust the carburettor correctly:
Screw 1 controls the full throttle range. If the motor jerks at full throttle, the mixture is too rich. You then have to turn screw 1
clockwise by ¼ turn and check the result with a test run. If the motor still jerks, you have to repeat the procedure described above.
If the motor stalls at full load, the motor is too lean. In that case you have to turn screw 1 anticlockwise by ¼ turn and check the
result with a test run. If necessary, repeat this procedure until the desired result is obtained.
Screw 2 controls the partial-load range. If the motor jerks during partial-load operation, the motor is set too rich. Turn screw 2
clockwise by 1/16 turn and check the result with a test run. If necessary, repeat the process until the desired result is obtained.
If the motor stalls if you accelerate abruptly, the motor is set too lean. In that case turn screw 2 anticlockwise by 1/16 turn. If
necessary, repeat this procedure until the desired result is obtained. The idling speed is set with screw 4.

7. Coil up the starter rope and let it end in the notch.
Carry out the remaining reassembly steps in reverse order.
When inserting the rope pulley in the starter housing, you
have to reapply pretension to the rope pulley.
8. When inserting the starter assembly, you have to spread
the white starter catches apart against their spring tension.
Thin rope ends are helpful in this regard.

The propeller consists of two halves and when assembled has
a length of 120 cm. Its weight is approx. 900 g. It is made of GRP,
which allows you to carry out minor repairs. It is compulsory
to rebalance the propeller in particular after repair.
Fasten the propeller on the hub with 6 screws and tighten it
with 12 Nm.
How do I balance the propeller?
Align the propeller vertically on the balancing device. If it
turns to one side, drill a 3.5 mm hole into the lighter half of the
propeller.
PROPELLER
14
Now fill this hole with resin until the propeller no longer turns
away to one side.
SNAP
MANUAL

Now check the imbalance in the same manner in a horizontal
position and if necessary, adjust the imbalance.
Caution: An imbalanced propeller subjects the motor to
unnecessary vibrations so that many components could be
destroyed within a short span of time.
Materials required to balance the propeller:
Balancing resin with curing agent, syringe and a pivoted
shaft to allow free turning of the propeller (balancing
device).
What do I need to repair the propeller?
Fibre glass spatula, spatula, abrasive paper.
PROPELLER

To the right an example of a propeller that may no longer be
repaired. If the damage is too extensive, a repair would be
dangerous. The repaired spot would have little adhesion and
could detach from the propeller at high speeds – danger of
injury.

Depending on the type of mounting, the gas handle is gripped
with the right or left hand. The retaining strap has a variable
size adjustment. Before take-off, the strap should be firmly
tightened.
The Respect gas handle is equipped with a switch at every
end of the pipe. One is used for starting ...
... the other one for switching off the motor.
GAS HANDLE RESPECT

The gas handle is also equipped with a cruising speed lock.
Once the cruising altitude is reached, it is possible to secure
the gas handle by means of the clamping lever. As holding the
gas lever in your hand for a long time is very strenuous, it can
be put across your legs when it is in a locked position. Your
hands are now free for other things.

The Airboss gas handle is also equipped with a button to
switch off the motor and where applicable a start button if an
E-starter is available.
First take the gas handle in your hand ...
... then grab the steering line and finally the A-line.

This harness has been specially designed for motor ope-
ration. Care has to be taken that no loose parts can get into
the propeller during operation. The pilot suspension can
permanently remain in the snap hooks.
The harness is secured with 3 catches - two leg catches and
one chest catch. It offers two different means of adjustment.
The first one consists of the clasps attached to the front seat
that are used to adjust the lowering and lifting of the seat.
During take-off, these should be slightly tightened to facilitate
sitting down into the harness after take-off. It is recommended
to completely lower the seat before landing so as to be able
to assume the most favourable landing stance. It is not
necessary to tighten the leg loops very firmly.
The harness is in addition equipped with 2 pockets that are
easy to reach while flying.
HARNESS AND SUSPENSION

The other means of adjustment regulates the sitting stance
during the flight. If it is very firmly tightened you sit more
upright, if you slacken it somewhat you can achieve a slightly
supine position.

Now kneel in front of the motor and pull the shoulder straps
over your shoulders.
After that, the pilot suspension is hooked into the motor’s
dropping device. Usually, the hindmost hole is used. The
dropping device should be activated in case of imminent
danger, e.g. water landing, fire at great altitudes or tree
landing. The device is triggered by pulling the two ribbons
on the dropping shackle outwards. As the motor is now no
longer connected to the canopy by means of the suspension,
the pilot is moved into an extremely supine position. Now
the motor easily slips off your shoulders. The landing is then
carried out without motor.
