10 TEAL 2 AV DETAILS
10.1 ARCHITECTURE
The AV is designed to be vertically integrated and fully modular, ensuring that each
payload, propulsion, and battery subsystem can be quickly repaired, replaced, and
upgraded. Each spares kit contains necessary parts and tools required to immediately
make repairs while in the field.
See the Field Repair and Maintenance appendix located at the end of this manual for more
information on repairing and replacing parts.
10.1.1 TEAL 2 SYSTEM POWER
The ON/OFF power switch for AV 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 AV to be recharged. The battery pack is not serviceable in the field but
is easily removed and replaced.
The AV does not support a
battery pack hot-swap. Be sure
to power down the battery pack
before removing and replacing it.
10.1.2 ANTENNAS
The AV 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.
10.1.3 ROTOR ARMS
The AV has foldable and replaceable rotor arms. The arms fold down and under the
bottom of the AV, 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.
10.1.4 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.
10.1.5 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
