Suggestion....buy another brand quad. I'm not kidding. I have a P2V+ V3 that was given to me with this problem fortunately I have another P2V+ that works fine. I can use the free one for ground station flights but these are my last DJI products. I am going to buy Yuneec products from now on. Hope you find a junk P2V+ for parts. Amazon wants $467.00 for the freakin module. You can buy a new DJI Phantom 3 Standard Quad for $499.00!
