ARCHITECTURE & RATIONALE
The Teal 2 is designed to be vertically integrated and
fully modular, ensuring that each payload, propulsion,
and battery system can be quickly repaired, replaced,
and upgraded. Each spares kit contains necessary parts
and tools required to immediately make repairs while
in the field.
For more information on repairing and replacing parts,
please see the FIELD REPAIR & MAINTENANCE
appendix at the end of this manual.
TEAL 2 SYSTEM POWER
The ON/OFF power switch for Teal 2 is built into the
battery pack. A 4-second press-and-hold of the battery
power button turns the pack on or off. The battery
pack must be removed from the Teal 2 to be
recharged. The battery pack is not serviceable in the
field but is easily removed and replaced.
The Teal 2 does not support a battery pack
hot-
swap. Be sure to power down the
battery pack before removing and replacing
it.
ANTENNAS
The Teal 2 antenna is highly flexible, providing for
greater crash survivability. When placed in its tactical
case, the case lid can be closed, bending the antenna(s)
down to the top case. The antennas are permanently
attached to the top cover and are not field-replaceable.
ROTOR ARMS
The Teal 2 has foldable and replaceable rotor arms. The
arms fold down and under the bottom of the Teal 2,
even with the propellers attached. No latching or
unlatching is necessary when folding the arms. When
folding, the arms give at a torque of about 7 in-lbs.
Locking the arms in the extended (flying) position
requires a torque of about 3 in-lbs.
PROPELLER MOTORS
A custom brushless DC motor is mounted to each
folding arms. These 3-phase motors spin at speeds up
to 14,000 rpm. Optimized motor drive algorithms
maximize the motors’ power, efficiency, and audible
signature. Note that individual motors cannot be
replaced if damaged – only complete arm assemblies
can be replaced.
PROPELLER ASSEMBLIES
Propeller assemblies are easily replaced in case of
breakage with a simple no-tools push-and-twist
method and are keyed so that a CCW one cannot be
mounted to a CW hub and vice-versa. Replacement
arms are prewired with the motor installed and are
easily swappable in the field by removing a single T8
Torx screw.
MULTI-FUNCTION BUTTON
A multi-function button is used during the process of
pairing Teal 2 to the TAC, among other functions,
including future functionality.
RESET/ FACTORY RESTORE BUTTON
The reset / factory restore button is recessed internally
and is accessed through a pin hole to prevent
accidental actuation. A paper clip or other small rigid
pin can be used to actuate it. Pressing and holding this
switch for at least 10 seconds before releasing initiates
the following functions:
• Clears all media on either the SD.
• Clears all pairing information, causing a full
radio settings re-program on the next pairing
attempt (but does not clear the radio settings
that are active on the radio).
• Sends a MAVLink message to PX4 to reset its
parameters to default.
• Clears flight logs.
