Helicopters:
• Use an earthing strap to connect the tail boom
to the chassis. Toothed-belt tail rotor drive
systems may require a "copper brush" to dissi-
pate electrical charges from the toothed belt. It
may also be necessary to connect the toothed-
belt pulleys electrically to the chassis.
• In electric-powered model helicopters it is
generally necessary to connect the tail boom to
the motor case.
• If the model is fitted with CFRP / GRP blades
and a carbon fibre tail boom, massive static
charges can be generated at high rotational
speeds when air humidity is low. To avoid this
an electrically conductive connection should be
present between the tail rotor gearbox and the
main rotor shaft. The use of anti-static sprays
(e.g. Kontakt Chemie) has also proved effec-
tive.
Range-checking:
• We recommend that a range check should be
carried out every time before you fly a new
model, or fly a model fitted with a new receiver.
Note that the model should not stand on the
ground for the check: it should be raised above
the ground by about 1 to 1.5 m. Use a plastic
or wooden table, box, carton etc. as a support
- never a metal object (camping table, etc.). No
electrically conductive objects (fences, cars.
etc.) should be in the vicinity, and your assi-
stant should not stand too close to the model.
• Start by switching the system on, but leave the
motor or engine switched off. Walk slowly away

from the model, and operate one control func-
tion slowly but continuously.
• While you increase the range, carefully watch
the control function on the model, and observe
whether it follows the stick movement accura-
tely, or occasionally stops or wavers. You may
find it easier to ask a friend to watch the control
function from a certain distance.
Turn the transmitter to left and right as you
increase the distance from the model, in order
to simulate different aerial positions relative to
the model.
• In Power-Down mode (range-check mode) you
should achieve a range of about 50 m. In most
cases the ground-range will be about 80 to 120
m, which is a very good result. If the value is
only about 40 m or less, then you should cer-
tainly not fly the model: seek out the cause of
the problem and eliminate it before flying.
• If this initial range-check is successful, repeat
the whole procedure with the motor running
(caution: secure the model well beforehand).
The range now achieved should be the same
or only slightly less (approx. 20% reduction is
acceptable). If the groundrange is substanti-
ally reduced, then the power system is causing
interference to the receiver. Running through
all the measures listed above should enable
you to cure the problem.
