Pulled this out of my P2V and hooked up an external NAZA puck instead. This unit is in perfect working condition. These are guaranteed to work in all Phantoms. They seem to sell for between $150 and $165 and do not include the compass. Will sell for $90 with free shipping via Priority Mail to the US only. Please, US addresses only, and only via Paypal. I am a verified Paypal seller for my RL business and will be more than happy to speak with you on the phone if you have any concerns. Please PM if interested.
