To make things easy for you guys, here’s a list on what’s inside the Harrier.

But first some notes on whats setup here:

• Buzzer
• Air Mode, Horizon mode on channel
• Auto trim and autotune
• Multiple OSD screens on a wheelknob
• Loiter/PosHold and RTH
• no differential thrust – makes no sense as the wing handles great without it
• LEDs switchable which comes in handy at low light conditions

Used components  (may contain affiliated links):

• Reptile S1100 Harrier Kit (in black)
• 2 x TowerPro MG92B servos
• 2x SunnySky X2216 1250kv
• GPS module Beitian BN-880
• Matek F405-WING FC running iNav (currently V2.2.1)
• 2 x Racerstar RS30A 30A Blheli_S OPTO 2-4S ESC or similar
• 2x 8045“ Props Aero-naut CAMcarbon Light Prop (nr 7216/12 and 7217/12)
• Buzzer
• LED connected to a switching controller
  • 2x Diatone DT-LED Flash bang LED in Orange (Nacelle)
  • 2x Diatone DT-LED Flash bang LED in White (front lights)
• RunCam Eagle 2 as fpv cam
• Gitup F1 running Firmware V1.2 Mod 1.6 for the 4K footage
• Battery:
  • 4s2p6000 Li-Ion pack giving 45-53min flight time
  • 4s5200 LiHv battery giving 30-40min of flight time
• iNav Radar module running Radar v1.6

CG – center of gravity at 300mm-305mm

ignore the note that are with the Harrier and says something about 2xxmm from the nose. The good CG is about 300-305mm from the nose!
