Willing to sell together or apart. Bought this for a specific project that never materialized. It's never been assembled or used. Naza M V2 - can support Phantom 1, 1.1, or 2, F450 or F550. New in box. Never used or even removed from packaging. Price: $250 F550 Kit: New in box, never assembled. I did start to mount the engines on the arms, but those can easily be removed. Never mounted arms to centerboard. Price: $300 I tried to price both these at slightly less than current market price. Let me know if you're interested. I can invoice you from Paypal to set up payment. As long as it's within CONUS, I'll throw in free UPS Ground shipping and provide the confirmation number. Intl shipping will be invoiced at direct cost.
