I purchased the NFZ unlock through Yuneec Skins and installed this afternoon. After ordering on the Yuneec Skins website, I got an email from them requesting my photo ID, a copy of my FAA remote pilot card and the ID number of my TH. The email also included a link to the GUI interface to be able to obtain the Typhoon H ID number. After emailing these three items back to Yuneec Skins, I got a call from John at Yuneec Skins to walk me through the unlock process. Kudos to John for the great customer service.
