Landing with the Boomerang 

 

  The travel of the brakes is enough for a clean stall in normal conditions without taking 
wraps around your hands. The low min. Sink and flyable min. Speed will help you to make a 
soft landing in all conditions. Remember, this is a dynamic high performance glider. Don´t do 
your last turn too late or too steep. It is easy to misjudge your speed and altitude.   
 
 
 

Packing instructions 
 

  We advise you to pack the glider ”accordion wise”. See drawing. 
This kind of packing procedure may take slightly longer, but conserves the rigidity in the 
profile reinforcements and the Rigifoils and is worth it in the long term. You will enjoy 
unadulterated performance, top speed, ease of take off and tuck resistance for years ahead. 
Sounds good, huh? 

 

 

 

Care and maintenance 

 

  Care should be taken with the small reinforcements of the Rigifoil System. They are 
generally very resistant, but should they become damaged, they can be replaced easily by an 
official GIN distributor or dealer.   
  If a line is damaged, please consult your dealer and have it replaced. The kevlar inside the 
sheath can take lots of pulling force without stretching, but is sensitive to bending with small 
radius. Damage is not always easy to see, so pre-flight check your glider meticulously. When 
not in use, store the glider in a dry place out of the sun. Take caution when transporting 
together with gasoline or solvents in a vehicle.
