If you're asking about FPV
goggles, the Headplay HD's are awesome. The resolution is 720 to match the 720 downlink from the craft. They look big, but when you try them out you'll see the virtue of being so big, because it's like an Imax screen inside, much larger than other goggles. They are very light on the head, made mostly of Styrofoam with a plastic shell. They only cost $250, a great value. You'll need to buy the HDMI cord to connect to the RC. These goggles will blow you away, so nice. However, if you're old like me you may have vision issues. I had to jury-rig 3.0 X reader glasses with an extra
magnifier lens to get the screen in focus. The 2 Fresnel lens options included with the Headplay HD were not enough for my old eyes.
