Watching the video it looks not that bat I have to admit. Using my videogoggles it's another thing.
I have two RC305 receivers on 5.8 like http://www.rc4y.com/bev-58ghz-pocket...iver-p-24.html
And yes, a laptop is no problem. I guess you have some test software for Windows? Don't think I can do anything but uploading new firmware with the standard software since I do not own your OSD yet.
Thanks for quick and great support,
