Heli Tower Patrol!!! FPV RC 3D Helicopter Danube Tower Donauturm Vienna Austria Wien Hubschrauber DC

Helicopter 3D aerobatics, keeping the people in the Danube Tower under surveillance (playing police helicopter) and chasing Prometreus’ FPV EasyStar plane.

This is the video of Prometreus, he killed me almost: http://www.youtube.com/watch?v=FXoqO …

26th and 27th 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 Mh transmitter (+ emergency booster)

Graupner/JR SMC-19 DS 40 MH 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 GH 400 mW video transmitter from BEVRC (www.bevrc.com) with small Lawmate 3 dBi antenna

Lawmate 1,3 GH (1.2, 1.3 GH ) video receiver with BEVRC 3 dBi antenna (upper plastic casing removed, should be better for 1280MH )

Video receiver powered with 11,1V LiPo battery

1,2 or 1,3 GH transmitters are legal in Austria with Radio (Ham) License between 1240 and 1300 MH up to 200W

I’m using channel 9 (1280 MH )

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 Ja 40-6-18. I could not see any lines with the Ja 40!!! But the soft start of the Ja is not good for autorotations…..

FPV Recording:

Video splitting with a simple Y-cable

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 Corel VideoStudio Pro X4

Compressing with Xvid, Single Pass, Quanti er 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
