Description and technical dates
DESCRIBTIONS AND TECHNICAL DATES The SilexX was developped specifically for use with a Paramotor but has good performance in thermals. The SilexX ist easy to pilot, and ideally suited for the recreational pilot. It is a pleasure to fly due to the easy handling and great stability. The planform of the SilexX is eliptical, slightly swept. This planform allows for a clean sail and profile with very few Attachment points. Few attachment points mean less lines that result in good glide due to less parasitic drag. The SilexX is designed from scratch. Mehrere computerberechnete. Many CAD designs where prototyped, tested and the best was selected. The profil selected has great stability, soft, forgiving reactions, easy handling and excellent performance. The closed cells have Dacron Reinforcements for best Stability. Dacron reinforcements at the attachment points spread the loads evenly. The air enters the SilexX through the open cells at the underside of the wing. Large Crossports are utilized for even pressure throughout the wing.

Description and technical dates
SILEXX SUSPENSIONSYSTEM The SilexX lines are manufactured from white polyethylen (Dyneeema) with a colored sheath. The suspension system is constructed from individual lines that are looped and sewn at both ends. A,B,C and D Lines are 1.5 mm diameter, middle Lines 1.2 mm and upper Lines 1.0 mm On the main brakeline the proper length is marked and it should not be changed to remain within certification. The A Lines, Stabilo Lines and the A risers are red for easy identification. The B Lines and all brake lines are yellow while all other lines are blue. There are 4 Risers per side. The A lines are the most forward followed by the B Lines where the Stabilo Line is also attached. The C lines follow and the rear Riser is the D lines. A line plan can be found at the rear of this manual.
IMPORTANT SAFETY NOTICE Maximum caution is advised. You are operating at your own risk! It is your duty to check your equipment before every flight. The Silexx may NOT be operated under the following conditions: - outside of minimum or maximum load rating - during rain, snow, turbulence or strong winf - in clouds or fog - In any aerobatic manner - by an inexperienced pilot

Speedsystem
SPEEDSYSTEM The SilxX can be fitted with an accellerator. The accellerator activates A,B and C Risers. The normal length of all Risers is 48 cm During accelaration the A Riser is shoertened by 16 cm, The B Riser 11 cm and the C Riser 6 cm. The D Risers stays the same.
SPEEDSYSTEM-FITTING The accellerator needs to be properly routed and should be easy to reach.

TRIMMER USE WITHOUT MOTOR For free flight the trimmers are NOT to be used and should remain in the fully closed position. The ring at the end of the trimmer must be installed in the carabiner to disable trimmer use during unpowered flight.
TRIMMER USE WITH MOTOR During motor flight the trimmers may be used to compensate for torque. Depending on the propeller rotation the left or right trimmer can be opened to achieve straight line flight under power. Both trimmers can be opened for faster flight.
BRAKE LINE ROUTING FOR MOTORING During motor flight the Brakelines can be routed through the additional set of lower pulleys. In this case, both the upper and lower pulleys are used. This will make it easier to reach the Brakelines and make it less likely to get the brake toggle caught in the propeller. The brake lines need to be lengthened by the additional distance between the pulleys.

Harness - Flying and Handling
HARNESS The SilexX is vertified only with the use of a GH type harness. All modern harness are of the GH type. Fixed Cross Bracing is NOT allowed and does NOT increase safety.
FLYING AND HANDLING PREFLIGHT CHECK AND MAINTENANCE The Glider needs to be thoroughly inspected before every flight and after long periods of storage.
ITEMS TO CHECK -
Stitching on the harness, Glider, Risers and Reserve All Quick Links and Carabiners Brakelines and knots all other lines all the way up all attachment points on the canopy the canopuy fabric the crossports and cellwalls
Don’t launch even with small problems! If you find signs of wear please contact your dealer.
LAY OUT THE GLIDER It is advised to lay out the glider in a Horseshoe Shape so that the A lines tension first. This is also known as the inverted V Layout. All Lines must be clear. Pay special attention to the brakelines. Makes sure there are NO Lines over the top of the glider as that will lead to an unrecoverable flight situation.
MAKESHIFTSTEARING In case of a Brakeline failure the Silexx can be steered with gentle pulls on the rear risers.
AKTIV FLYING Aktive flying is advised. You constantly make small adjustments to keep the Glider pressurized and overhead. A little tesnsion in the brakelines will gibe feedback from the Canopy. For example when entering an updraft release the brakes to allow the glider to speed up. When leaving an updraft apply some brakes to slow any surge. Should the pressure in the brakes decrease, indicating an impending depressurization you can apply some brake to avoid that.

Flying and Handling
FLYING WITH ACCELERARTION During accelerated flight the glider is more likely to depressurize thus you should use the accelerated flight mode in calm air only and never close to the ground. - Do not set the brake lines too short - Never Fly accelerated in turbulent conditions! - Never Release the brake lines! - Should the glider collapse release the accelerator.
TOWING The Silex is very suitable for towing. Do not use too much tension and climb gradually, not too steeply. Do not use brakes during tow other than for steering.

Descent Possibility
DESCENT POSSIBILITY SPIRAL DIVE A Spiral dive can be achieved with holding one brake down until the glider enters the dive. The dive can be adjusted with more or less inside brake and outside brake can be applied to stabilize the canopy. The spiral dive is the fastest method to reduce altitude but can be very dangerous if the pilot is not familiar with the maneuver. High G forces occur during a spiral and the inexperienced pilot needs to be very careful! If you experience any discomfort the spiral should be stopped immediately. To exit from the dive slowly release the inside brake and give the glider time to continue the turn for a few revolutions. Spiral dives should be practiced during a safety clinic!
B LINE STALL Both B Risers are being pulled down symetrically until the glider enters the stall. To exit, quickly release both B Risers at the same time. If the glider horsehoes during the B Line stall, exit immediately. It may be necessary to pump both brakes to recover from the horseshoe. B Line Stall should be practiced during a Safety Clinic.
BIG EARS Big Ears are a gentle decent maneuvers that retains forward speed. To enter Big Ears pull both outside A Lines until the Ears fold under. You can steer the glider with weight shift during Big Ears You can also apply the accelerator with Big Ears to further increase sink rate and forward speed. To recover from Big Ears simply release the lines, one at a time. Pumping the brakes expedites the exit. All Decent Maneuvers should be practiced in calm air with plenty of altitude, best during a safety clinic.

Extreme Maneuvers
EXTREME MANEUVERS ASSYMETRIC CLOSURES By applying a small amount of opposite brake the Silexx can be kept from turning. During a large assymetric closure only small amounts of opposite brake should be used to keep from stalling. Should the glider not open a few deep pumps on the collapese side will help open the closure.
CRAVATTE A cravatte ist one or more Lines over the top of the glider. Opposite brake is applied to keep from entering an involuntary spiral dive. To recover from the cravatte you can try: - Pump the brake on the affected side - Pull down the Stabilo Line on the affected side - If unable to recover, a full stall can be used by highly experienced pilots, otherwise the - reserve parachute should be activated.
FRONTAL COLLAPSE During te exit from a thermal or upon entering a strong downdraft the front of the glider can symmetrically collapse. A small amount of both brakes will open the glider quickly. The Silexx usually opens on its own.
PARACHUTAL STALL (DEEP STALL) There is no forward speed with a high sink rate. During a slow exit from a B line stall parachutage may occur. A porous fabric and streched A lines will make a Glider more subcepptable for a deep stall. To recover push the A lines forward and/or apply the accelerator.
Caution: If any brake is applied during deep stall the glider will immediately full stall. If close to the ground it is advised to land using the PLF (Parachute landing fall) rather than trying to exit deep stall and risk a big surge.
FULL STALL Take a wrap on both brake lines and pull them under the seat. Hold them there and resist the tension. You must hold the stall until the glider has come back overhead. To exit, slowly bring both hands up when the glider is overhead. Not behind.
If the Full Stall is exited incorrectly the glider can surge very much and the pilot can fall through or into the glider. Fullstalls are very dangerous and need to be practiced only during a safety class over water!

Extreme Maneuvers - Materials
NEGATIVE SPIN A negative spin is a rotation around the span of the glider. One side of the wing flies forward while other flies backward.
What causes Spins: - One brake is being applied too fast and too much. - During slow flight one brake is applied too much An accidental spin should be exited righ away and the glider will recover quickly. If crossbracing on the harness is pulled tight the glider will spin easier.
WINGOVERS Alternating turns with high bank angles.
Caution: Fullstall, Spins and wing overs more than 90 degrees are considered dangerous aerobatics !
MATERIALS The Silexx is made from best quality materials.
SEGEL UND PROFILE Top Surface Toray Undersaurface Toray Ribs: Toray Leading Edge Reinforcements
Torray Toray Toray Dacron
LINES We use New Dyneema PPSL200 because of the low strech and longevity.
RISERS Risers are made from best quality 25 mm Polyester manufactured by Gueth and Wolf with highest values for strengt and stability.

Storage and Check
STORAGE AND CHECK With proper care the Silexx will remain airworthy for several years. Don´t forget. Your life depends on it!
STORAGE Store the glider loosely folded, dry , out of the sun and away from chemicals. Moisture is an enemy, always store the glider dry, best indoors in a heated/air conditioned room.
CLEANING Any cleaning will remove from the lifespan of the fabric, avoid cleaning of possible. Use only a soft, wet cloth. No chemicals at all.
REPAIR Use only an approved repair facility.
AGING UV Rays are the biggest enemy. Never leave the glider in the sun if you are not using it.
LINES Do not overload individual lines as they may stretch. Do not kink the lines. Any damage requires replacement of the affected line. Compare the lines before replacement for correct lenght and only use the proper line material from an approved repair facility Kite the glider after line replacement to check for proper routing.
TIPS Keep Glider and lines clean as dirt particles will cause damage. If ines snag on the ground they can be damaged. Don’t step on the lines! Make sure no forein objects enter the glider, like rocks, sand of snow as it may cause a stall. Sharp objects will damage the fabric! During high winds if the canopy hits the ground it can cause internal damage After landing avoid the glider hitting the ground with the leading edge as this can cause damage. After tree and/or water landings the lines need to be checked. If the glider contacts salt water immediately rinse in fresh water. A line plan is attached or can be obtained from your dealer.

2 years Inspection - Closing Comments
2 YEARS INSPECTION After 2 years the glider needs to be inspected by an approved repair facility. This check should be confirmed through a DHV stamp in the glider If you forget this to do within all 2 years the SilexX loose the “Musterzulassung” Germany approvement and all guarantie.
MODIFICATIONS TO THE GLIDER No Modifications whatsoever are allowed and will void any warranty.
CLOSING COMMENTS The Silexx is the result of high end development. The glider will last many years if treated and cared for properly. Respect and an appreciation of the potential dangers of personal flight are required for a succesful flying career. Even the safest Glider can not prevent pilot error. Keep in mind that any airsport is potentially dangerous and your safety is up to you! You may only fly with proper back protection, helmet and reserve parachute.
Fly at your own risk We wish you plenty of sunshine, Safe flight and happy landings See you in the Sky!
