5.2 Charging US-1 US-1 can be safely charged when the battery cells are between 32 F and 104 F. Should the cells be too cold or too warm, the charger will turn off. The vehicle will resume charging onche cells are within the above temperature range.
The US-1 in its hardshell case with charger weighs roughly 75 pounds. Be certain to maneuver the case and its contents with two people to limit the risk of injury. When moving US-1 outside of its case, grasp the vehicle firmly with both hands. In the event of an acci-...
6.3 Deploying US-1 1. Gently lift the US-1 out of its case and place it on its side. 2. Unfold each leg and attach the feet. Attach each foot to the inner leg first, then the outer leg. Ensure the detents click into place.
6.5 Powering On 1. To power on US-1, press and hold the black power button. 2. To power on the handset, slide the switch on the bottom right of the handset to the ‘ON’ position. 3. Ensure the tablet is powered on and the USB cable is con- nected to the handset, and launch the IAGS application.
, and green when the action has been completed. Remember that the back of the US-1 is the side of the airframe with the power button; this should correspond to the tail of the small airplane shown during calibration.

(a) Ensure the Failsafe Action is set to ”Return Mode”. (b) Ensure the Battery Warn Level is set as desired (20% recommended). (c) Ensure the Battery Failsafe Level is set as desired (15% recommended). (d) Ensure the Battery Emergency Level is set as desired (5% recommended).
7.2 Arming and Taking off Arming US-1 starts the propellers spinning and allows the vehicle to take off. If US-1 is armed but no takeoff is performed, the vehicle will disarm after roughly 8 seconds. Before arming: 1.
3. 3. To take off, advance the left stick away from the operator until the aircraft becomes airborne. 7.3 Controlling US-1 in Flight In Position Hold mode, the aircraft will not move or drift when the sticks are centered.
7.4 Landing US-1 1. Before landing US-1, tilt the camera upward to protect its lens from dust and debris. 2. To land, hover over the desired landing spot and pull the left stick towards the operator until the vehicle lands and disarms.
In the high posi- tion, full-screen thermal is enabled. 7.6 US-1 Autonomous Flight US-1 supports autonomous flight modes to reduce pilot workload. Remember that autonomous operation is not a replacement for a qualified operator. If an operator can’t perform an action manually, they shouldn’t attempt it autonomously.
To perform an Automatic Landing: 1. Fly over the desired landing spot. 2. Before landing US-1, tilt the camera upward to protect its lens from dust and debris. 3. From the Fly view, press the ’Land’ button on the left.
To automatically go to a location while flying: 1. In Fly view, press a location on the map. 2. Select ’Go to Location’. Remember, US-1 will not avoid obsta- cles. Ensure there are no obstacles above the vehicle’s current altitude. Do not select ’Orbit Location’.
UAS. Though Battery consumption varies depending on wind, flight profile, and payload. The battery voltage of a flying US-1 with a FLIR will decrease roughly 1 volt per 10 minutes of operation. Operators should know the following voltages and their mean-...
9. Securely latch the hardshell case before moving. 8 US-1 Operational Limitations 8.1 Wind US-1 is capable of flying in sustained wind speeds of up to 25 MPH and gusts of 30 MPH. In high wind conditions, US-1’s battery will deplete faster than usual.
9 Emergency Procedures 9.1 Flyaway Procedures In position mode, the US-1 uses GPS to maintain its location. In the extremely unlikely event of a GPS or radio error, a US-1 in position mode could begin moving when no command is given , causing a “Flyaway”.
