4.2.4 The GPS Stand and Clip
The GPS Stand is designed for multirotors, where it lifts the GPS/MAG sufficiently above the
multirotor frame to avoid electromagnetic interference. However, it can be used for any
type of model. The stand must be mounted vertically, and the base can be mounted either
by placing it under 2 or more of the multirotor’s arm mounting bolts, or with closed cell,
double sided foam tape.
The stand also has a slot that can be used to neatly route the GPS cable.
Make sure that the screw that holds the mounting clip to the stand is tightened sufficiently
to keep the GPS from rotating easily, but don’t tighten it so tightly that the threads are stripped.
If the stand comes loose or rotates during flight and the compass is enabled, GPS flight modes such as
RTH and loiter will not work correctly, and the model may fly away at high speed when in these modes!
Consider using a small amount of glue or double sided foam tape on the top of the GPS stalk where it
meets the clip, to permanently set the direction the GPS/MAG is facing.
4.3 Mounting the Current Sensor/PSU
The Current Sensor/PSU can be mounted with double sided foam tape, or with other methods. Before
mounting the Current Sensor/PSU, make sure that your ESC/Motor connector, battery connector and video
harness will reach.
It is recommended that the Current Sensor/PSU be mounted so that cooling air can flow into the one of the
openings of the current sensor during flight.
4.4 Mounting the Optional Pitot Tube
If you have the optional airspeed sensor, the pitot tube should be mounted as follows.
Using two lengths of the included small diameter silicon tube, the pressure and static connections of the pitot
tube connect to the “+” and “-”
ports of the MicroSensor,
respectively, as shown below.
It is best to mount the pitot tube in
your model first, then determine
where you will mount the sensor,
and then cut the two lengths of
silicon tube so they reach between
the two. Note that the sensor itself
can be mounted anywhere in the
model.
Follow these guidelines when
mounting the pitot tube:
1) The pickup end of the pitot tube (the silver colored tip) should be pointing toward the direction of the
model’s travel. While best results will be obtained if the pitot tube is perfectly aligned with the direction
of travel in both axes, the “Prandtl” design of the tube will compensate somewhat for higher angles of
attack.
