Austria's Highest Skyscraper: • VIENNA'S HIGHEST LEVEL...
Enercon E-126: World's biggest and most powerful wind turbine in Potzneusiedl, Austria!!!
Weltgrößtes Windrad im Burgenland, ENERCON E126
Crawler cranes Terex- Demag CC 2800-1, CC 9100-1 and Liebherr LR 1200
24th and 25th FPV helicopter flight
Live video feed, video from onboard camera gets transmitted in real time to the video goggles.
FPV= acronym for "First Person View"
Setup:
Standard Thunder Tiger Mini Titan E325
Aluminum rotor head
Aluminum washout base
ACE RC BLC-40 ESC; Settings: Helicopter mode without governor (Throttle curves), Standard timing, Quick throttle response, No brake, Light discharge protection
Hacker A20-6XL motor without cooling fan (broken at a crash), 15 tooth pinion
Thunder Power 11,1V 3s 20C 2600mAh LiPo battery (weighs only 188 g)
Turnigy 3A Low RF Noise external BEC (UBEC), 6V voltage output
6,3V 2200μF buffer capacitor for the BEC, but not necessary
3x EMAX ES08A analog swash plate servos from BEVRC, 10.5mm servo arm length (shorter servo arm= better resolution!!!)
1x EMAX ES08A analog tail servo, 8.5mm servo arm length
Robbe- Futaba GY-240 gyro
Align 325 PRO rotor blades, they are good enough for soft 3D
Align Tail Rotor Blades for T-Rex 450 (plastic)
Graupner- JR MX-16S, 40 Mhz transmitter (+ emergency booster)
Graupner/JR SMC-19 DS 40 MHz receiver with 1,75m antenna (Lamda/4)
The Multiplex RX-7 SYNTH DS IPD is defective, it was the reason for the last crash
Approx. 2600 rpm headspeed
+- 9° blade pitch
FPV Setup:
1,3 GHz 400 mW video transmitter from BEVRC (www.bevrc.com) with small Lawmate 3 dBi antenna
Lawmate 1,3 GHz (1.2, 1.3 GHz) video receiver with BEVRC 3 dBi antenna (upper plastic casing removed, should be better for 1280MHz)
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 through the EH balancer connector
Ferrite ring (= toroid), 32V 100µF and 16V 1000µF Capacitors against interference (= LC- filter), the BLC-40 has much more noise than the Kontronik Jazz 40-6-18. I could not see any lines with the Jazz 40!!! But the soft start of the Jazz is not good for autorotations.....
FPV Recording:
Video splitting with a simple Y-cable
Canon MVX200i Mini DV PAL Camcorder (DV-AVI, 720x576, 25 fps)
Deinterlacing with "Alparysoft Deinterlace" (Advanced method, ME search enabled) ,saved with "Cedocida DV Codec" and Virtual Dub
Editing with Corel VideoStudio Pro X4
Compressing with Xvid, Single Pass, Quantizer 2 (approx. 72 MB per minute), MP3 256 kps CBR Stereo
This is the best possible quality in my opinion (with this camera, transmitter setup)
AUW 981 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. 850 Euro
Altogether approx. 2500 Euro (Flight Simulator, transmitter, batteries, charger, video goggles, FPV video recorder....)
Typical crash costs: 50- 300 Euro
