Welcome to MAESTRO! Don’t let its size fool you, MAESTRO is many features that will
help you insure your aircraft is ready for a safe flight plus several features
to help you diagnose problems and help you setup a new aircraft.
MAESTRO incorporates the latest in microcontroller technologies to provide you the
following capabilities:
Battery testing features
No load voltage monitoring
Loaded voltage monitoring
Programmable load resistance
Calculation of battery cell impedance
Low voltage warning
Charge now error message
Visual Battery level indicator
Two programmable voltage test profiles
High low battery voltage monitoring
Pulse width monitoring
Servo cycler
Servo positioning
MAESTRO can be configured to the needs of each pilot. The voltage alarm and warning
levels are programmable as well as servo cycler positions; even the startup
message can be customized to display your name and AMA number if you like.
MAESTRO can be configured at the factory for you or with the addition of a
low cost interface you can configure the parameters yourself.
MAESTRO is very simple to use! Only 1 button, 1 red light and a small display packaged
in a small enclosure. Several operating modes are supported, to start MAESTRO
simply connect it to your radio system, using the charge jack, and you will
see the startup display and your systems no load battery voltage. Press the
button to read the loaded voltage, press the button one more time and MAESTRO
will calculate your battery packs cell impedance! If the battery voltage is
below a user defined limit, MAESTRO will warn you that your batteries are getting
low. If your batteries are below a critical limit, MAESTRO will tell you not
to fly! MEASTRO will fit in your pocket, or your flight box making it easy
to always have the tools you need to make sure its safe to fly.
MAESTRO’s voltage test options can be programmed at the factory for your convenience
or you can purchase a programming adapter. Connecting cables are also configurable
at the factory. The MAESTRO always comes with both male and female connectors
for added flexibility and support of servo cycling modes.
