A Tragic RC FPV Helicopter Crash!!! Failure Heli Accident Crashing Crashes Funny Epic Fails Fun Air

21st FPV helicopter flight

Only minor damage, I guess "only" 50 Euro and some hours of work......
The crash was caused by a receiver failure. I had no problems at the last two flights at the wind turbine, but now the receiver only has a jerky servo output and it fails randomly. It is a Multiplex RX-7 SYNTH DS IPD receiver, the range is outstanding but it is defective somehow.

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!) or RockAmp 11,1V 3s 2200mAh 30C (193g, but very powerful!!!)
3x EMAX ES08A swash plate servos from BEVRC, 10.5mm servo arm length
1x Futaba S3154 digital tail servo, 8.5mm servo arm length
Robbe- Futaba GY-240 gyro
BBT Maniac 321 CFK blades, 2nd choice
Align Tail Rotor Blades for T-Rex 450 (plastic)
Graupner- JR MX-16S, 40 Mhz transmitter (+ emergency booster)
Multiplex RX-7 SYNTH DS IPD 40 MHz receiver with 1,75m antenna (Lamda/4)
Approx. 2600 rpm headspeed
+- 7° 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, ferrite ring used against interference (I had some brightness problems, much better now!)
32V 100µF Capacitor against interference, 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 RX-7 DS IPD doesn't like the switching BEC next to it- reduced range!!! And 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 Ulead Videostudio 11
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 953 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. 900 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

[muni86]

@MrMarijuanaKills Yes, my ego....

[MrProjectdjim007]

and ur boom is still ok .. lols if that was mine my boom would of gone .. always does for some reason..???

even on the lightest landings.. nice setup though.

[muni86]

@MrProjectdjim007 It was bent down slightly. I could fix it with my hands, but very exhausting.

[muni86]

@cracker442 I am that guy ;-)

[locouk]

I'm glad I'm not the only one!

[flightoftheunknown]

I stopped watching the moment I heard that awful music.

[FPVUAV]

Dont waste your money on a clone dude

[hallobaaaby]

i think it craches because of the music!

[yeogav]

was it worth uploading this vid? I think not.

[azezrtyuuiopqsdfghjk]

Why are the blades always broken and flybar bend???

[Blackenedbarman]

;-(

[muni86]

@muni86 No, the RC receiver "Multiplex RX-7 Synth DS IPD" is defective! Excellent range but loss of control sometimes. There is also a jerky servo output when moving the controls fast.

The E-MAX servos are excellent so far!
