1x 67919 Tailpipe
Properly adjust the belts tension.
Remember, too much friction costs
energy. Energy is flight time and flight
performance!
Make sure that the belt runs straight in the tailboom.
Insert the tailboom into the frame.
Twist the belt by 90° to the left!
Pull the belt over the pulley.
Pull the tailboom backwards, adjust the belts tension
and tighten the M2 x 30 mm screws.
The belts tension:
If you can compress the belt by
abt. 5 mm the tension is just right.
If you can compress the belt
completely, the tension is low.
If you can hardly compress the
belt, the tension is too tight.
Loosen the two M2 x 30 mm screw
for inserting the tailpipe.
Tighten the screws again after
adjusting the belt tension.
Have a break here. Check all screws and check the moving parts for
easy operation. Pay special attention to the levers of both rotors and
the gear meshing of the central drive unit. Don't forget to use
screw-lock on certain marked parts. Do not underestimate the belt
drive! Once it is properly adjusted it moves with hardly any friction.
Misadjustment can cause a lot of damage and is a waste of energy.
