A few months ago, I tested latency differences between the Mobius, Sony Super HAD II 600TVL and Effio-V cameras. Today I received the Headplay HD FPV goggles I pre-ordered a few months ago.
I did a quick comparison test showing latency differences between the Headplay goggles and a Skyflight Black Pearl RC801 monitor. Here’s the video.

This was shot with an iPhone 6 at 240fps. Youtube shows the video at 60fps. At 60fps, the Black Pearl shows approximately 2 frames of latency. The Headplay goggles show 3-4 frames of latency. I don’t have an isolated measure of the latency in the Headplay goggles, but they have 16-33ms more latency than the Black Pearl monitor. In real numbers, the latency of the entire FPV system with the Black Pearl monitor is about 33 milliseconds. With the Headplay, the entire system has roughly a 50-67ms latency.
So, it’s this too much for FPV? Probably not. Some very skilled FPV pilots use an Effio-V with setups that generate a combined latency of roughly 100ms. It is worth noting however when you’re picking parts for your FPV system. If you use a higher latency camera like the Mobius or Effio-V, then the extra latency might be noticable. With a fast FPV camera like the 600TVL, you should still have a system that’s fast enough for almost all pilots.
The picture and field of view on the Headplay goggles are very good. I have an upgraded setup of Hobby King goggles with an 800×480 pixel screen. I wasn’t expecting the Headplay goggles to be much better than those, but the difference is striking. Eye focus is much easier too. I’m looking forward to flying them soon.
