GRAUPNER heim UNI-Mechanik 2000 Mode D'emploi page 48

Foreword
The Graupner/Heim UNI-mechanics 2000 set is a self-supporting helicopter mechanical
aggregate for two-stroke motors of 10 ... 15 cc capacity.
In conjunction with a fuselage kit (available separately) the system produces a model helicopter
which is equally suitable for training, aerobatics and competition work.
Good accessibility to all components makes maintenance and repair work easy and trouble-
free, both at the flying site and in the workshop.
The UNI-Mechanics 2000 can be completed with either a simple cabin and tubular tail boom to
form a trainer for beginners and more advanced practice flying, or installed in any of a wide
range of beautiful GRP fuselages. In every case the result is a model helicopter whose all-up
weight is very low, and therefore possesses considerable reserves of performance. This is the
result of the extensive exploitation of high-strength, vibration-absorbing glass fibre reinforced
nylon. The excess performance can be utilised by the experienced pilot for power-sapping
aerobatics, but it also provides ample reserves for the beginner who finds it difficult to set up his
model exactly perfectly. The extra performance also copes effortlessly with additional features
such as a training landing gear.
The Graupner/Heim UNI-Mechanics 2000 set offers the following outstanding design features:
• Mechanical construction based primarily on vibration-absorbing, fatigue-free, high-strength
glass fibre reinforced nylon.
• Highly efficient two-stage main gearbox with durable, machined Delrin gears.
• Replaceable gears enable the user to adjust the gearbox reduction ratio to suit different
sizes of model and main rotor diameter.
• Excellent access to all vital components, making the system easy to repair and maintain.
• Servo installation immediately below the swashplate for rigid, direct, backlash-free control
linkages. All mixing is carried out by the transmitter electronics, which results in accurate
overall control response.
• High-efficiency cooling fan for the motor.
• „In-line" silencer arrangement in the bottom section of the mechanics keeps the fuselage
slim, and is ideal for rear-exhaust motors; the system can also accommodate side-exhaust
motors.
