  1. FPV, all lives out of the visual aspect, from the point of view from within the plane / helicopter. We do deploy redundant Rx's at the ground station .... but how about redundant Tx from the plane / helicopter we fly from? (if you consider "weight" not to be the limiting factor) I'm certainly a digital person (with 0's and 1's) so what will it take to make this work out: Camera ---> Tx #1 ---> same frequency towards Rx \----> Tx #2 ---> same frequency towards Rx[/codebox] Q1: what will it take to "beef" up the analog video signal from the cam to provide enough

    Kilrah already found a better method Cheers, relee

    PS: thought I should start a new thread, where people can find each other & help during the first FPV steps. Cheers, relee
  4. Yes Terry I did - but only towards the left side (back) - since by design (5 mm) it wasn't touching the top .... but then the screw came
  5. Changes: 1) soldered the 4 corners of the Tx chassis 2) moved the Tx from the alu stand-up to point downwards (this made the antenna stick "ouside" the heli) 3) chaged the setup of the cam from 2 screws to my old setup: a bit of foam on each side & cable ties Next I went to the same spot again and did the distance check .... but this time with the heli (quite heavy after a while). When I came back and checked the recording: crystal clear So with good hope, I put the main battery in and started the engine .... again this terrible noise. Stopped everything and took the h
  6. here are the videos Main flight direction - North Main flight direction - West
  7. @ Mr. RC-CAM What does this mean? In a digital world (with 0's and 1's) that just tells me: solder the SMA connector instead of the existing antenna: ...use the existing ground as the ground for the SMA connector and the existing "signal" for the SMA signal ... is that right?
  8. @ Terry: no mobile phone / WiFi for the next 1000 meters @ Mr. CR-Cam: can't I use a regular 8 USD SMA based rubber duck antenna? no external interference - other than the heli - used exactly the same location / setup (Tx+Cam+Rx+Recording+Car+Shoes+Person) while doing a "walking" range check the day before so far implemented: 1) soldered every 4 corners of the Tx (sorry for the warranty) 2) orientation of the antenna is now towards the bottom 3) metal plate removed (cooking time's ahead - since the Tx get's quite warm) 4) mounted the Tx with a shock absorbing double sided sticky t
  9. I could flip the setup - so that the antenna points downwards ... through a hole in the frame. Can't I replace the antenna against a rubber duck?
  10. Thanks for your ongoing help with this .... I wouldn't knew where to turn otherwise. To answer your question about the "ghost audio" I don't have any other proof. Only during spin-up and spin-down I can easily identify the audio signal - otherwise it's way to loud. Here is a VIDEO during the flight today to show the video issues I'm facing with. The Tx / heli nose points towards 0 degrees (North), the diversity Rx is at about 110 degrees, Antenna is left of the heli ~ 270 degrees. So the antenna is right between the heli and the Rx. What I don't like at all about the Tx is, that the "
  11. the new video has audio in it .... which by definition shouldn't be there since the Audio line was CUT. I didn't wanted to bother you with another crappy video (noisy again) so I only put the sequence of the spin-up into the video, where you can listen to the spin up of the rotor I'll also test the vibration thing .... with the cheap Cam incl. Tx I used a sticky foam (since I couldn't get the screws in) ... excellent point, thanks Any good explanation, why the video has audio in it, when there is no mic attached? And yes, the main motor runs on 8s1p; Tx has it's own battery 2s1p (
  12. I sense the pest got me .... simply cutting the audio line between the cam and the Tx was fixing the "clapping" .... but when I took the gear today to the field .... still noise I must admit, I'm a "digital" person ... no great sense for analogue technology / or even high frequency. and here is the video where you can hear the motor spinning up: LINK Q: do I have to ground the Tx audio-in signal ? Any help greatly appreciated. Here's the picture of the cut wire:
  13. Thanks again Mr.RC-Cam Issue fixed by removing the white (audio) signal - the audio wouldn't have been of too much help inside the helicopter anyhow
  14. Thanks folks, vibrations are not the cause. This heli is extremely vibration arm - check it out on youtube.com author "DreleeD" - all movies for "DNHP Centurio". Thanks Mr. RC-Cam for your hint on the microphone. CONFIRMED ISSUE clapping Any good advise on how to remove / isolate the mic? Trillions of thanks to you folks - who get us newbies going. Cheers, relee
