Help!
goggle video cuts out

The video cuts I experience in my goggles are longer and more frequent than what I see in the recorded video. I am using a powered video splitter amplifier, so I don't think the splitting is the issue. I am suspecting something about the goggles shutting down once they don't see a video signal for a couple seconds whereas the video camera I'm using for recording doesn't turn on or shut off based on if it's receiving a signal or not.

Has anyone else noticed this, and is there any solution for it?

I'm using both the Icuiti and the RangeVideo goggles and they are either fully charged or running on AC.

I've noticed the same thing when my friend/spotter decided to "help me" by staying next to my Rx antenna and pointing it to the plane, while he had his cell phone with Bluetooth enabled in his pocked.

Does your video receiver use a "blue screen" if it is getting no signal or does it show static snow?

Do you get the exact same behaivior if the displays are connected directly to the video receiver and there is not an image?

Which ICUITI's? The ICUITI's are sensitive to signal since they are 3D capable unless you have the AV320's. I haven't tried them yet.

The blank screen is the power saving mode in the Kopin Modules. It turns the backlight off whenever it sees signal degradation (or in this application, static). Its even more annoying on an RC car where you get a lot more signal breakup. The Oriscape video headsets (the flip down visor type) don't have this problem - that's the main reason I used this module as opposed to the Kopin module in the RCV922. Its better to have a static image than no image! -Fat Shark

Yes Jack, I got the same problem. Effectively the picture come black when the video signal is to weak. I did not have this problem with my old goggle. We can do nothing. Our goggle are not design for FPV...

Thanks, guys, for confirming the explanation to this problem. It's good to understand what's happening and know that it can't be fixed (unless I were to get the Oriscapes). Now I can relax

Can I ask what model you are having trouble with? Im in the market for a good pair and was looking at the ones Vova has on RangeVideo. I see he has 2 models now, and would like to know what models to avoid.

Thanks.. Jon

Jon, I don't think the problem is with those specific goggles, but just with any goggle that has this energy-saving feature that powers off the goggle (to some extent) when it thinks it's not receiving a signal. The ones I got from RangeVideo (the Rvision 640x480) and also the AV230 I have from Icuiti both do this, and it sounds like only something like the Oriscape goggles mentioned by fatshark don't, but then those are the visor type and I don't know if you want that.

In summary I would highly recommend the Rvision goggles from RangeVideo.

Has anyone besides myself tried using the high res DV920 ICUITI's? The AV230 is their bargian version. As you might expect from the name the AV230's are 320x240 vs. the Rvisions 640x480.

Holy Cow! The VR920's are $400 WITH 3 axis head tracking. WOW http://www.icuiti.com/products/vr920.html. No wonder there is a back log of orders.

How will you use the 3 axis head tracking, it's not compatible with our radio.
$245 for FH545 goggle + Aeropix headtracker is around the same price.

I am using a PCTx AND/OR external tracker, (TrackR1) to my TX so I can use both.

Anyone that has the Z-800's can do the same thing with the internal tracker built in.
