  • Insert bare end into leg receptacles (with foot pad facing away)

  • CAUTION: Ensure the collar is tight and properly threaded around the leg. 

Install Arms In Matching sockets

  • Remove Arms from arm case

  • Use guide pins to align

  • Push inward to mate

  • Arms may be stiff. This is normal

  • DANGER: ENSURE correct arm placement.  A to A, B to B, C to C, D to D.  Improper arm placement may lead to abnormal flight performance.

Secure Arm Joints with Supplied Hardware

  • With arms fully mated, insert arm nuts and hand tighten

  • There are two wingnuts per arm

  • One upper and one lower

  • DANGER: TWO wingnuts must be used per arm to ensure a secure connection.

  • Use Carbon Wrench to tighten all wingnuts

  • Use moderate pressure

  • Do not overtighten

Batteries

  • Center batteries

  • Secure with battery straps

  • Make sure battery strap buckles do not crush corners of batteries

  • Note: Do not connect power wires yet

Propellers

  • Check condition

  • CAUTION: Damaged propellers can cause reduced flight performance.

GPS Masts

  • Unfold GPS masts to the extended position shown in the photo

  • CAUTION: Improperly deployed masts will lead to erratic flight characteristics.

  • Lock mast in extended position using light to moderate pressure on wingnut



R/C Antennas

  • Rotate the 90deg antenna to the position shown. Where it is clear of the hub.

Move Aircraft to RTL Safe Location

  • Move Aircraft to a safe takeoff location

  • This location is also the return to land location that will be used for landing in the event of a loss of R/C link or an RTL triggered by the pilot

Connect All Batteries

  • Connect all batteries

  • Make sure all connectors are fully seated

BEFORE TAKEOFF

Hardware Safety Switch

  • Press and hold hardware safety button for approximately one second

  • The button is located on the left GPS unit

  • The small red indicator light around the button will blink when the aircraft is disarmed and incapable of arming

  • The small indicator light will be solid red when the aircraft is capable of arming

R/C Controller

  • Set Flight Mode to desired mode for takeoff

    • A typical takeoff will be in loiter

  • Ensure other switch positions are as desired

Check Battery Voltage

  • Check the battery voltage before takeoff

  • Fully charged voltage should be 49.5V or greater

  • Minimum recommended takeoff voltage is 46.0V

NORMAL TAKEOFF

Area

  • Verify area is clear

  • Announce takeoff

Arm Vehicle

  • Left Control Stick -- Down & Right

Climb

  • Raise throttle to takeoff and climb
