Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

  1. Funny you should say that ! I have done some more on a sunny day and all seemed ok. Played back on the A1 and PC MP10 no bother.

    When I came to import the video into Movie Maker MM said the file could not be imported as it had not been indexed ( I think this may be my fault as I renamed the file while it was still in the PVR H: drive))

    I had to down load MS encoder and that allowed me to import the file. trouble was it had made it jerky and pixelated in places, especially around the prop strobing

    Perhaps I should have just transferred the file to my PC then renamed it.

    Our aim is to get some really good air to air footage. My system is ok if you have two really good pilots (we are not) but Group Leader has the answer I think with his pan and tilt mechanism we just need to get his camera sorted out

  2. Well Here it is at long last - The first decentish video from a model aeroplane that I have been able to acieve to date.

    It is a big file at 34Meg but if your connection can handle it it can be found at:

    http://www.alanmorgandesigns.co.uk/video/tigermoth.wmv

    The camera is a bullet type helmet cam from rf concepts sporting 480 TVL powered by a 4.8 nicad via a dc dc converter ( Thanks Mr RC Cam)

    The recoring is done on board by a Mustek PVR A1 strapped to the centre section

    The ant you can see in the pilot space is for a 2.4 GHZ down link but it is not in use.

    2 video sequences were shot , one faing forward and one facing aft these were then spliced together in Movie Maker and the audio etc added.

    let me know what you think and what might be the best "save as " compression ratio to use to get it even better

  3. well guys it took me a while and a lot of advice from you but I finally got there

    Heres how I can get superb aerial video with zero dropouts recorded in the aircraft

    The Camera:

    CCD 480TVL 12V waterproof bullet camera and microphone all loomed up marketed as a Helmet Cam £165 from RF concepts

    The recorder:

    Mustek PVR A-1 190g with 512meg sd card from pixmania £123.90

    Tx:

    Uk legal 10mw 2.4 Ghz 4 channel with fitted rubber duck Maplins UK £34.99

    For power:

    2100MaH nMih 4.8v pack 4.8v to 12v booster chip Farnell UK £24

    Rx

    2.4 GHz Rx I had laying about with GP patch

    To view

    Eye trex goggles Ebay £77

    As my planes are all pretty big it was decided to use the spare room to the max

    What I have been trying to do is transmit good video to the ground - then record it

    so I have been recording what I saw

    the Mustek A1 is small enough to fit in the plane and is wired directly to the camera

    the A1 is set to record before the flight and stopped at the end the result perfect video with no range or multipath interference problems

    the camera is Y leaded into the Tx and the signal is tranmitted to the ground and I use the eye trex to view the action along with multipath interference

    What I am now doing is recording great, clean video in the air and viewing what the camera sees, on the ground

    I can then play back the video and sound on the A1 then transfer it to my Pc then burn to cd and view on TV MAGIC

    The bits of test movie are huge files but I will post on here when I can

    Thanks again Folks

  4. Hi there

    I bought my eyetrx on ebay for £77 although I have seen them for around £110 -£160

    There are two types the 200 series and the more expensive 700 series I GOT THE 200 SERIES

    the eyetrex goggle are fitted with phono type plugs so that they will accept a signal from almost any video and audio source I personally think they are great

    ALL IN ALL A GREAT INVESTMENT - EVEN WORK ON ps2

    Although they come with a mains adaptor I run mine from a 7.2 V buggy pack with a suitable plug

    On its first trial I was flying around while my buddy was looking through the goggles and he started to feel nauseous . Its that realistic

    The effect is a 56" screen about 2m in front of you and there are earphones fitted too

    another bonus is that they have an adjustable nose piece so if you wear prescription glasses you can wear the eyetrex over the top

  5. Hi terry

    Thanks for that I just found a Tx at Maplin with the following specs

    Input voltage = 12 V DC

    Power input (Current drawn) = 120mA

    Frequency Deviation = 200KHz

    Output power 10mW (12V DC, 50 Ohm load)

    Audio input = High impedance, 2V p-p

    Audio sub carrier = 6.5MHz

    Video input = 75 Ohm, 1 V p-p

    Frequency 2.434,2.453,2.473 & 2.411 GHz

    Operating temp 0-40 deg C

    Dimensions 55 x 37 x 12 mm

    2.453 & 2.473 match with Matt Klarich's freq set 2 diversity RX Ive asked him if its a match

    Hoping

    Ahab

  6. Hi again people. I have a question fo you all

    Is there available, a plug and play TX with a 10 mw output that is compatible with one of Matt Klarich's diversity receivers

    I am desperate to get a setup that is LEGAL in the UK

    Do Uk tx's operate on the same freuency sets ?

    set 1 2.410 2.430 2.450 2.470

    set 2 2.413 2.433 2.453 2.473

    Can I buy a 50Mw Tx that has been "dumbed down" to 10mw

    All I really want is good stuff I can use in UK

    Any ideas

  7. Hi Philthyy

    thanks for getting back to me. I "guestimated " that my setup was running at 1.16 so many folk have said that is the most likely so I made a patch ant scaling the 2.4 gHz one to suit

    I found an F connector and soldered this to the reflector with a piece of copper wire suitable for the F socket soldered directly to the element

    This gave me about twice the range as before.

    Then I had a brainwave! I remember reading (maybe Here) that the optimum length for the TX whip is 65mm Mine was 110 so I did a ground test with a pal watching the monitor I walked away with the Tx. my pal held his arm in the air and wnen the picture started to fail he dropped his arm. I then lopped the TX ant to 65 mm and walked on another 75 yard before we lost signal again.

    In tha air the results were really dramatic with an astounding increase in range still some dropout but in editable chuncks rather than great lumps.

    I am looking to get a really good setup soon so I can take some "atmosheric" video from some of my own designed planes
