I found an easier way to have a HQ cam for FPV flying and at the same time recording my aerial fun.
Until now I had a laptop with a framegrabber at my base-station to record the video which my receiver got. This of course had limitations such as 640x480 and radio interference.

Now my JayTech Cheapo 720p SD-Card camcorder does the job. Recording is done in H264 and the quality is good for the price of about 120$!

Bonus of using the video from the cam: before takeoff i press rec - so a REC-TIMER shows me the duration of my flying on my goggles!
The colors are more vivid and light-balancing is also better as on an small FPV cam.

The weight is about 133gram - I had to move my battery to adjust the CG.

    Mario, are you using the HD camcorders video output for transmission? Have you noticed a slight time lag, he camera not being "real time"?

    Hi, yes I'm using the "TV out" of the cam for video downlink (see rcschim.blogspot.com for details - in german). I only noticed a short delay or "wobbling" in low light conditions - the cam uses longer exposure times here.
    But under bright sunlight you have no problems!

    Gute Bildqualität und schöne Gegend! War es an dem Tag windig? Etwas wackelige Aufnahmen.

    Danke! Ja, gegen Mittag ist es immer windiger geworden. Ein Teil der Wackler kam aber sicher auch durch Nervosität zu Stande (immerhin war's eigentlich erst mein 2ter richtiger FPV Flug). Den e-Stabi der Billig-Cam hab ich weggelassen - der ist nicht besonders gut. Hier muß ich erst eine Software-Lösung suchen - um zumindest die kleineren Wackler rauszurechnen.

    Mfg,

    das "wackeln" könnte auch von dem etwas kleiner blickwinkel kommen...weitwinkel verzeihen das ja mehr...hast du ne ahnung was für eien brennweite das ist? oder wieviel blickwinkel?

    Guter Ansatz - das ist einer der Kritikpunkte der Cam - ein Weitwinkel wäre mir hier wesentlich lieber (auch wegen der Übersichtlichkeit). 7mm sind angegeben - das müsste so ca. 35-40mm KB entsprechen.
    Meine IF OSC Cam hingegen hat 3,6mm glaub ich - ist schon wesentlich besser.
    Wahrscheinlich werd ich zum Fliegen jetzt nach dem Crash mit der Twinstar eh wieder die IF Cam nehmen müssen. Und ich werd's mit meinem Heli versuchen - wird sicher spannend.

    You HD picture quality is a real improvement, but (blech, sorry airsickness) it was slightly shaky. No offense intended. Have you tried Paul Thompson's approach of not downlinking your video but rather saving it on your onboard cam? BTW- Nice recovery about halfway thru this video. Thought you were going to crash! TFTV (thanks for the video).
