We don't know who came up with this switch first, but we liked it so much that we figured we should sell it! We're calling it the "Warranty Voider" because it does exactly that. Neither FatShark or RMRC can honor the warranty once this is completed. This mod requires one to have acquired certain skills over their hobby career such as rotary tool skills so good you could carve Tim's face into a pumpkin and soldering skills so clean that a NASA engineer would try and fail to replicate. Not really, but if this scares you, please don't attempt this modification on your expensive goggles!
