Wow, that is a portly ship! They look so sleek and sexy, but put 'em on a scale...

About the FOV, I've heard that can be a problem, showing the fuselage (nose) too much. I'd like to see someone mount it on a TS II...
Looking forward to the video, Dario!
Thanks for the reply! It is going to be a big disappointment if this can't be resolved. Maybe Thomas Black at DPC could help. He designed and built several special filters to make 900MHz video more compatable with GPS.

I think Thomas will have the same problem. just takes some time to have a dig around without voiding warranties. Here's a couple of pictures of the Vert & Horiz waveforms if anybody see's something I missed let me know. Upper trace is from GoPro and lower is from KX-191. The vert looks off but it's the black bars in the video (I have tried it in 4x3 mode and same effect)

I think this problem can be related to the presense of the GoPro OSD on the screen. I remember someone had this same problem with Aiptek cameras, and I had some problems stacking two RVOSD's one after another.
For all the common factor is OSd added to the screen.
I searched the Aiptek thread on this and while nothing was found on the combination of A-HD and RVOSD there were comments that it did work with the EzOSD and Remzibi OSD. The only issue being that the camera and external OSD may put data in the same spot on the screen.
When playing back movies the Gopro osd is on for a short time then go's away and still the Rvosd is screwed up. So It's not the camera's osd problem. I'll check the DC levels of the cameras and see whats the differance. I'll get back later.
First off, here is a good link someone found for a good price on the GoPro

Read through this thread and watch the Video from Wobby, he talks about a simple USB trick to put in in Live view through the video out cables.
So, i couldnt really tell from these forums, im at work and cant watch Videos from firewalls, but has anyone Got the RvOSD to work on the GoPro? So far RvOSD is number 1 on my to buy list for an OSD, but if it wont work with the GoPro I will go with something else. The GoPro Quality is just bar none the best for an FPV cam and also the Fact you can Record on the SD card during the Flight... Check out user man2000me on Vimeo for the Quality of this thing.
BTW, looking at the plane pics from above, i would also prob leave as much as the case on i could to protect the camera.
Found the problem. I made a amature mistake . I didn't check video levels when loaded. As I discovered the GoPro has a 1 V P-P (DC) UNPLUGED, but when attached to either my monitor or OSD output drops to .65 V P-P. So I plug in my KX-191 into my monitor and adjusted level (I have micropot in video line), I got same effect when reduced below .8 volts. So we need to have a buffer amplifier with varaible output to osd to get it to work properly. Some of the GoPro units must have higher level outs then others. Thats why some work and others dont.
RVOSD input has a 75ohm resistor to be compatible with the standard for input/output video signals. You can remove this resistor on the OSD and the Gopro level should go back to 1Vpp. However it will need to be restored to use with other cameras. Make sure that you remove the resistor from the graphic board pictured bellow, removing the R7 resistor from the main board will cause catastrophic damage to the OSD.

I'll try it and let you know. thanks Alex
