Today I received the Foxtech D1 recorder. http://www.foxtechfpv.com/mini-d1-qu...der-p-451.html
I hooked it up to my groundstation suitcase, containing 15" lcd, Fatshark Dominator and Eagletree diversity controller.
The D1 board is VERY small (60x45mm). It is fragile, and should be wrapped in heatshrink (NO packing tape as it gets warm!). The connection plugs sits very tight, and will not come loose in any situasion. The menusystem is very easy to set up with the remote. There is no buttons on the board, so you have to use the remote.
The first few tests went bad. The unit reset it self after just 30-45 seconds (only when recording). I thought it had a defect. Then I realized that around my GS suitcase I had a computer running, baby call on, dragonlink tx on, my charger setup running, fpv-cam on and the video tx on my plane on. It was all situated about 1-2m from the recorder. When I shut down everything except video tx, fpv-cam and dragonlink, the unit worked perfect! It records everything, included static/no signal.
The unit work as it should. Playback is only a few clicks on the remote away. You can also delete files on your SD card.
The weather here is pretty bad these days, so I maybe have to wait until weekend to record a flight with my Ritewing Zephyr 2. When I go for my next flight, I will upload the video and post it here.

Hi RemiWM,
Are you using PAL video? Does the foxtech SD card recorder crop the video edges?
I am wondering due to horizontal resolution being only 705 instead of the normal PAL 756?

Yes, I'm using PAL.
I had to use the VGA recording settings to make the video fit in my screen. When playing the playback, it did not crop the edges.
I tried the D1 recording settings, but then the picture on playback mode didn't show all the info.

Is VGA NTSC? Does that mean it is shrinking the video to NTSC resolution?
Would you say the recorded video is pretty much as good as the original video?
Cheers for helping me out

VGA is 640x576. I don't know if that is NTSC. It's PAL that is the normal standard in Europe. I had to choose VGA recording so I can see all info on the screen when playback. The recorded video is almost as good as the original transmittet video. I would say that the quality is the same as you see on almost every fpv onboard recordings on youtube.

Ill have to google video resolutions and formats
PAL I know is 720x576, NTSC is 720x480, so I dunno if the VGA recording would be stretching (well, shrinking) the video horizontally a little to record PAL?

Nope...it's not listed on the FPV-Japan site. You could send Ren an e-mail to see what he says. I will say the display is very crisp though...not blocky at all...at least not to my eyes.

Well I received my JapanDVR and like it so far. I haven't been able to FPV or record with it yet (and won't for a long time) but here are a couple observations of mine in regards to comparing it to the PV500ECO.

The JDVRs remote works from almost any angle. The 500ECOs remote has to be pointed directly at it, which is on the side. This made it a pain to use as I have it countersunk into my GCS.

The remote record button for the JDVR is a simple push button which could be changed to any other type of button to mount in a GCS. The ECO remote record button is a proprietary slide button. But, the JDVR remote button plugs into the AV out so you cant use the remote button and an external monitor at the same time.

The JDVR can't (as far as I can find out) display video on the built in screen and an external monitor at the same time. The ECO can.

The ECO records in .asf format. This can be finicky during playback. The .asf format was designed for streaming video. I think this is why searching through an asf video locks up the media player some times. The JDVR records in .avi format which is much easier to work with.

Oh, and the "Black Box FPV Flight Recorder" is the same. I downloaded the manual for it and it shows all the same buttons etc.

At work we use the Lawmate PV1000 and I am going to try to record some with the JDVR and compare it directly to the PV1000 but I imagine the quality will be the same on the PV1000 as my ECO500.

I am thinking of putting either the JDVR or ECO in my FPV planes (Skywalker and X8) to get some really clear video with the OSD. whichever I don't use in the plane will be in my GCS.

Does this mean that the JDVR cannot take a single video input from the VRx, record and display realtime, as well as output to a pair of goggles? Would i need to split the video prior to the JDVR so that i can record with the JDVR and see the footage in my goggles?
