GRAUPNER G-BOOSTER 160 – Manual 1.91
Warning:
Compared to an ducted fan model aircraft, the model with a jet engine reaches much higher
airspeeds due to the considerably higher exhaust speed at the same static thrust. The achievable
airspeeds of more than 300 km/h (190 mph) normally exceed the speed range an aircraft model is
approved for (risk of rudder flutter, sudden nose dives and overload of the fuselage and the
servos).
Therefore always take care of the following: After taking off and accelerating to normal airspeed,
always pull the throttle back. For horizontal flight, 50 % of thrust is sufficient to achieve the same
flight performance as with an ducted fan !
Only use the full thrust of the jet engine for takeoff and for vertical climbing in aerobatics!
For limiting the airspeed, we highly recommend using the optionally available airspeed sensor (part
no. 6813.15)!
Warranty Conditions
The warranty covers the free repair or replacement of parts that exhibit proven defects of
fabrication or material defects within the warranty period of 24 months from the date of
purchase. Any further claims are excluded. Costs for packaging and shipping are paid by the

Graupner or to the service contractor in charge for the respective country, a detailed description

the defect of the part or the model is caused by an accident, improper handling or improper use.
Removing or damaging the safety seal on the cover of the jet engine voids the warranty.
