b) Checking the Drive Mechanics
Before commissioning your model helicopter, you need to check the drive mechanics. Only if the mechanics work
securely, without play and absolutely smoothly can be model fly with the lowest possible energy expenditure. For this
reason, you should check the model function before each flight.
For this, carefully turn the main rotor back and forth and check
the interaction of the main gear (1) and the motor pinion (2).
The gears must securely fit into each other without catching or
showing too much friction.
The motor shaft with the drive pinion must be aligned perfectly
straight and must not be eccentric.
The tail rotor must be easily turned by hand and the motor shaft
(see fig. 53, item 2) must be perfectly straight for vibration-free
operation.
The holding screws (3) of the rotor blades (4) must only be
tightened to where the rotor blades may fold down under their
dead weight when the helicopter is tilted to the side.
Therefore, never turn the holding screws in so tightly that the
rotor blades can no longer move.
c) Inserting the Flight Battery
The charged flight battery (1) is slid into the battery holder (2)
below the skid brackets. The battery connection cable (3) must
point backwards.
