14th, 15th and 16th FPV helicopter flight Live video feed, video from onboard camera gets transmitted in real time to the video goggles. FPV= abbreviation for “First Person View”.

FPV Setup:
1,3 GHz 400 mW video transmitter and receiver from BEVRC (www.bevrc.com) with stock 3 dBi antenna (upper plastic casing removed, should be better for 1280MHz) on RX and small Lawmate 3 dBi antenna on TX
Video receiver powered with 11,1V LiPo battery
1,2 or 1,3 GHz transmitters are legal in Austria with Radio (Ham) License between 1240 and 1300 MHz up to 200W
I’m using channel 9 (1280 MHz)
WDR700 (= KPC-DNR700PHB) PAL camera (Sony Super HADII CCD), factory (= default) settings, I’ve tried other settings but default is the best in my opinion
Fat Shark RCV922 Aviator Edition video goggles
Microphone
Weight FPV gear: approx. 100 g
Powering the FPV gear with the 3s flight battery, ferrite ring used against interference (I had some brightness problems, much better now!)

FPV Recording:
Canon MVX200i Mini DV PAL Camcorder (DV-AVI, 720×576, 25 fps)
Deinterlacing with “Alparysoft Deinterlace” (Advanced method, ME search enabled) ,saved with “Cedocida DV Codec” and Virtual Dub
Editing with Ulead Videostudio 11
Compressing with Xvid, Single Pass, Quantizer 4 (approx. 55 MB per minute), MP3 256 kps CBR Stereo
This is the best possible quality in my opinion (with this camera, transmitter setup)

AUW 974 g
Maximum flight time (hovering, slow flying): 10 min. (260 mAh/min energy consumption)
Average flight time: 7 min.
Range: approx. 800m with this setup

Costs:
Heli, camera approx. 1000 Euro (special setup for hard 3D flight)
Altogether approx. 2500 Euro (Flight Simulator, transmitter, batteries, charger, video goggles, FPV video recorder….)

Typical crash costs: 50 – 300 Euro
