Instruction Manual for the Airspeed MicroSensor V3
Document Version 2.0
Thank you for your purchase! This instruction manual will guide you through the installation and operation of your Airspeed MicroSensor
V3 (the MicroSensor). Please read the entire manual carefully before proceeding. If, after you read the manual, you have further
questions or problems, see the Support page on
http://www.eagletreesystems.com for additional information, or email us at

updated if changes were made after printing, or if you want to view the manual on your computer.
Intended Uses
The Airspeed Microsensor is intended to be used exclusively for recreational purposes in model planes, boats and cars. Other uses are not
supported. Further, using the Microsensor in situations where its use or failure could result in loss of life, bodily injury or property damage is
expressly prohibited.
What the MicroSensor Does
The MicroSensor uses a Prandtl style pitot-static tube to measure airspeed, just as full sized planes do. When used standalone, the
MicroSensor displays your maximum speed on the built-in 7 segment LED display. The maximum speed continues to be updated and
displayed on the LED, until you turn power off and on the MicroSensor. When power is turned off and on, the maximum speed from the last
flight is displayed, and now the MicroSensor is ready to record your next maximum speed (even if it is lower than the previous maximum
speed).
Additionally, the MicroSensor can be connected to your eLogger (any version) to provide airspeed data for your entire flight. When
connected to the eLogger, airspeed can be displayed and graphed using the eLogger’s Windows software.
IMPORTANT: It is extremely unlikely that the installation of the MicroSensor will affect your model’s radio range or control. But, as
always after making an electronics change to your model, it is very important that you range and function test your model once the
MicroSensor is installed to ensure that there is no impact on your system.
Packing List
Your package should include the following: The MicroSensor, a machined brass and aluminum Prandtl style pitot-static tube, the Standalone
Cable, approximately 3 feet (1 meter) of small diameter silicon hose, and a printed version of this manual. NOTE: Additional Pitot Tube
kits are available for purchase on our website, for use with multiple models.
Installing the Pitot Tube and MicroSensor in your Model
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 in Figure 1. It is best to mount the pitot tube in your model first, then determine where
you will mount the MicroSensor,
and then cut the two lengths of
silicon tube so they reach between
the two.
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
