Thank you for purchasing the Hangar 9 Angle Pro™
4-in-1 Digital Control Throw & Incidence Meter. The
Angle Pro™ allows ultra precision measurements of
control throws, wing and tail incidence as well as engine
thrust angles to 1/10
th
of a degree. You will also find the
Angle Pro to be a handy tool around the shop allowing
precision angular measurements of many of your building
projects and works great as a precision level. Its patented
sensor system utilizes the comparative force of gravity
acting upon dual accelerometers to precisely determine
angles. The angle pro features an acquire function that
allows you to zero the unit at any angle, especially helpful
when adjusting control throws. The hold function holds
the last angle measured for easy reference.
Note: The Angle Pro comes calibrated
from the factory with a battery installed.
When replacing the battery it’s necessary to
recalibrate the unit (see calibration below).
Features
• Patented technology works on models of all types
& sizes (U.S. Patent 6880258)
• Easily measures control throws
• Incidence attachments allows precise digital
measurement of wing, tail & thrust angles
• Clamps firmly and evenly to most control surfaces
• Reset ‘zero’ at any angle – no need to level
the airplane
• Hold function allows the last reading to be stored
• 18-inch bar included
Measuring control throw
• Attach the meter to the control throw clamp via the
fitting on the back of the meter.
• Attach the clamp to the aircrafts control surface as
shown.
• Turn on the radio and center the trim.
• Press the acquire button to zero the angle.
• Using the transmitter deflect the control
surface fully in one direction and record
control surface angle.
• Now record the angle in the opposite direction.
• Make the appropriate travel adjustments to
achieve the desired control throw.
• To measure the rudder control throw it is
necessary to place the fuselage on its side.
