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ywiththelowestpossibleenergyexpenditure.Forthis
reason,youshouldcheckthemodelfunctionbeforeeachight.
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t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g.53,item2)mustbeperfectlystraightforvibration-free
operation.
The holding screws (3) of the rotor blades (4) must only be tight-
ened 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.
