VIENNA’S HIGHEST LEVEL: DC TOWER 1, Insane 3D FPV RC Helicopter Stunts Building Heli Skyscraper Top

Vienna’s and FPV’s highest level.

DC (acronym for Donau City) Tower 1:
Height: 220m, 60 floors
Finished in summer 2013
Right now approx. 2/3 of the final height: 150m

32nd, 33rd and 34th 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”

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!) or RockAmp 11,1V 3s 2200mAh 30C (193g, but very powerful)
Turnigy 3A Low RF Noise external BEC (UBEC), 6V voltage output
6,3V 2200?F 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 Robbe FS550 BB Carbon Digital Speed tail servo, 8mm servo arm length
Robbe- Futaba GY-520 gyro (F3C flight mode, fast response)
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)
Approx. 2550 rpm headspeed
+11° -10° blade pitch

FPV Setup:
1,3 GHz 400 mW video transmitter from BEVRC ( 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
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
Weight FPV gear: approx. 100 g
Powering the FPV gear with the 3s flight battery through the EH balancer connector
Ferrite ring (= toroid), 16V 1000µF Capacitor 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, 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, Quantizer 2 (approx. 72 MB per minute), MP3 256 kps CBR Stereo (I take PCM 16bit, 48000Hz, Stereo now because Corel VideoStudio Pro X4 has no MP3 option anymore)
This is the best possible quality in my opinion (with this camera, transmitter setup)

AUW 980 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

Heli, camera approx. 850 Euro

Buy Syma X5SW

This is Syma X5SW Quadcopter with WIFI FPV Camera. It’s the same old Syma X5C Quadcopter but this time it is equipped with a WIFI Enabled camera that sends live video, and still shots directly to your smartphone via a live WIFI link. Now you can view the video coming from Syma X5SW on your Smartphone, Android or iPhone and take pictures and record videos with just one click on respective icons. All pictures and videos are stored directly on your Android or iPhone. It’s a very light weight quadcopter, so flying it outdoors, if there are winds, this quadcopter is not going to fly well. This quadcopter needs calm days to fly outdoors, else you better stay indoors with this quad.

Camera Live WIFI Transmission has a serious and dreaded delay so you do not want to fly FPV with this feature. Also the recorded pictures and videos are not of that good quality. They are still old school low resolution pictures and videos that in no way we can call HD. Its standard definition camera, not High definition

Nonetheless is a neat little fun quadcopter.
You can order it here
