Check the weather carefully when planning your flight! Some favorite sites and apps to check the weather include:

Drones

Beta FPV

The Beta FPV Cetus Pro is a small drone we use for indoor flight training. It is moderately difficult to fly, and so trains the pilot to react to drifting and yawing of the drone, and flying "first person".

Getting Started

  • This drone is for INDOOR USE only. It CAN fly outside, but is easily lost.
  • Batteries and controllers charge with USB. Batteries only last a few minutes.
  • Before arming: Make sure throttle is down and all switches (SA to SD) are back/down. This is common to all transmitters of this type.
  • To arm: Flip "SA" switch up to arm, down to disarm.
  • Speed: Speed is controlled with the 3-position "SC" switch. Down is slow, up is fast.

Battery charging

  • Batteries are small 1S, single-cell, nominally 3.3 volts per cell. They charge via a USB-C charger.
  • Place used batteries in the used controller until they can be charged.
  • Charging batteries should not be left unattended.
  • Controller is charged via USB-C.

DJI Avata

A small, sub 250 gram drone useful for pilot development and FPV flying. It cannot be used to fly between waypoints.

Preparing to fly

Getting Started

  • DJI drones and controllers start with a short followed by a long press on the power button.
  • Plug your phone to the goggles and start DJI Fly.
  • In order, turn on the controller, goggles, then drone. Always be sure to turn on your controller before your drone!
  • Press the "lock" button two times to arm. Long-press to take off to a height of 1.2 meters. Long press again to land.
  • Pressing the Lock button once in flight freezes it in position; press again to release. Tilting the controller rotates the craft. Trigger moves forward and back. Joystick moves up and down, and left and right. Tilting forward in flight moves the drone up or down. It can also move the camera gimbal up and down. Press and hold Mode button to initiate RTH. If landing from altitude, use joystick to adjust position if needed.

Other Controls

  • Mode button toggles Normal and Sport modes.
  • Shutter button: press once to take a photo, hold down to take video. Press again to stop.
  • FN dial controls camera settings, viewable in goggles. Press and hold to save setting.
  • Speed settings can be controlled in the Goggle menus.

Pairing / Linking

Controllers should be paired already, but if new controllers are needed you can initiate pairing on a graphical controller using a menu. On the drone, turn it on, and then hold the power button for 5 seconds to complete pairing. On the RC Motion 2, power on and hold the power button for 5 seconds to initiate pairing. Googles are linked the same way.

Autel Evo II V3

Autel produces small consumer drones commensurate with DJI's Mavic drones. We use the Autel Evo II V3 for training, which includes smart controller for mission planning. The Autel features a 1 inch CMOS imaging sensor, 40 minutes of flight time, 15 km transmission range, and 360° obstacle avoidance.

Operation

  • Power on the controller and drone with a single long-press of the power button.
  • Arm the drone by pushing both sticks in and down.
  • The charging hub can charge four batteries and the controller simultaneously. The LED indicates the charge mode, and the button at the top changes the mode. Blue is parallel charging mode meaning it will charge the lowest battery first then charge two batteries (at half rate) at a time until both are 100%. When it is green it is in Sequential charging mode which means it will start charging the battery with the highest level first then move to the next one. [source]

Mavic 3T

  • RGB Camera Specs: DFOV 84%, 4000x3000 (12 MP), 1/2 CMOS sensor
  • Thermal Camera Specs: DFOV 61%, 640x512 (0.3 MP)
