Electrical earth
An electrical connection must be created as an earth between the tail boom,
the motor crankcase and the helicopter chassis. Note that carbon is a
conductive material! Belt drives inside the tail boom are particularly dangerous,
as they act as a high voltagte generator. Cables running along the tail boom
may conduct sparks to receiver and servos.
On-board location
The mounting surface should be solid and should not "give", as this could ge-
nerate resonance effects.For Position mode: the higher the installation loca-
tion in the model, the smoother the stabilisation effect in position mode at low
altitude, and the larger the possible gain setting you can safely use. In many
models a suitable location is one side of the tail rotor servo, or - using the
mounting bracket supplied - the tail boom, the tail rotor servo, the chassis or
the fuselage nose.
Installed attitude
Vertical, with optical sensor facing down.
Any of the four possible directions can be used.
Unobstructed view between the sensor and the ground
The cross-section of the vision cone is square, with an open angle of 15° x 15°.
For this reason you must arrange an unobstructed square vertically below the
sensor, with at least the side length of (safety tolerance included)
S = window size (15mm) + [0,28 * distance from window]
(see drawing on the left side).
It is important that neither the aerial wire nor anything else can get in the way
of the vision beam!
Installation in an enclosed fuselage
Cut an opening in the fuselage (see above for size); alternatively do not cut a
hole (no sensor view), and manage without position mode. In this case cover
the sensor window with dark adhesive tape.
If you do this, you can only exploit horizontal mode, and not position mode.
