This little beauty can help transform goggles without a module bay. Taking advantage of AV in and Out, this will allow you to run modules like Rapidfire, Wildfire or Achilles on goggles that otherwise rely on their internal receivers.
Often it is the receivers that wear out in a pair of goggles before everything else. This option from Skyzone could actually help you to revive a dead or dying pair of goggles. Or buy if you fly in high multipathing environments, like bando’s or places with strong WIFI interference.
