I've worn several different brands and models of FPV goggles. While some may be slightly better than others, I've yet to find any goggles that I thought were particularly comfortable. I tend to devote a good bit of time prior to every FPV flight fidgeting with my goggles to get them positioned just right. Their poor fit was something that I tolerated for the thrill of flying FPV. Recently, I decided to take a more proactive approach to the problem.
A popular modification for FPV goggles is to mate them to the frame of ski goggles. These goggles typically have a much larger frame than their FPV cousins, which makes them more comfortable and easier to position correctly. I tried this modification on my Skyzone FPV goggles and I'm very happy with the result.
A Proven Mod Method
I didn't feel any need to innovate with this project, so I searched the web to see how other modelers have tackled goggle mods. I found that Jim T Graham from RC Groups posted a tutorial back in 2013 that also used Skyzone goggles. I used Jim's guide as my starting point and pushed forward.
I chose to use different ski goggles than Mr. Graham (actually, he used motorcycle goggles). That deviation created significant differences in the challenges of our respective projects. Some aspects that were no issue for Jim required me to think a bit, and vice-versa. Although there is considerable overlap in our processes, I think that they are sufficiently different to warrant a separate overview.
The goggles I chose are just something cheap I found on Amazon. When shopping for goggles, don't worry about the lens coloring since you'll be discarding that bit in the initial steps of the modification.
