Let me start by saying that if a P2 is assembled correctly, there isn't an affordable quad that can touch it. Ok. I ordered a "Production Kit" from Dronefly.com. After all was said and done I had spent a considerable amount of cheddar for a worthless and poorly assembled unit. The intereference board wasn't grounded and was on the outside of the hull so it was totally useless....basically a passthrough board. The IOSD was also on the outside introducing it to more interference. The gimbal was bad right off the bat. I sent it back on my dime. It came back after replacing the main board on the hull.(?) Whatever. I flew it once and the problem (drooping) was still there. The gimbal went dead. I sent it back a second time and they would not warranty the H3-3D. I had to buy another gimbal granted at a reduced price. Now there was no feed from the GoPro and again....no warranty. I sent the unit to a professional drone guy. He expressed that the unit was a joke as far as the assembly goes. He said that it was put together in haste and with no regard to electronic placement to maximize efficiency. I shipped the unit to him and from the pictures and video I get now it is a totally different photography platform. HE EVEN FIXED THE GOPRO! I am out over 600.00 for what I should have gotten the first time from Dronefly. If you want the guys name and facebook page....PM me. This guy is awesome....period. His work is perfect and his prices are even better. His communication is on the spot and your project will be documented with progression in pictures! Bad Dronefly......baaaaad Dronefly.
