So first let me start by saying a couple of weeks ago I bought the Headplay Goggles for flying. When I received them I couldn't see and had to buy lenses to go with them. Even after I wasn't impressed with the view, I have mono vision contacts so Headplay without diopter adjustments are a problem. Last night on this forum I read about the Litchi app now having FPV for use with cheap glasses. I did some research and settled on the BlitzWolf VR https://www.amazon.com/gp/product/B01AJSKIDG/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1 glasses for a whopping $26.99. I bought the app for $22.99 so I was all in for under $50. Compare that to $250 for the Headplay and $100 for the controller HDMI mod and a few more bucks for lenses and you can see the difference in price. As for performance, the view blew away what I was getting in Headplay, again not blaming headplay but my vision. However, to have a system that works great, small self contained with no battery etc is a pleasure. Now for my question. About 10 minutes into my flight I started to lose the image and I was close by. Controller was reporting 100% HD. I took the headset off and went back to flying from the app and still the image would disappear for a good bit then come back and this went in until I ended the flight. Anyone have an idea what might have caused this?
