I purchased a phantom 2 from B&H photo on a sale for a reconditioned unit. I paid $349. The catch was there was no warranty as it is. I jumped in and took the risk. I started out great and simple but had a rough encounter with the tree. it was my fault. after that the GPS lights would not come on any would not read the battery as a DJ DJ I model. I thought it was a bad cable from the connection pins to the board and replaced it myself. that seemed to work but right away it was very intermittent sometimes it would work sometimes it wouldn't. so I sent off the unit to drone fly for repair. their deal is $99.00 for all the labor to repair and evaluate the unit. then if you need parts you have to pay them that too. Arrived yesterday at drone fly and they called me right away. but the news was not good it looks like the nav system is busted. $229.00 for replacement. the dilemma is to pay and keep going or have them send it back part it out and go from there. I think I have a big case of drone fever and I'm going to throw more money down the DJI Trail. Anyone have any thoughts or alternatives?
