QWinOutF550 Airframe RC Hexacopter Drone Kit DIY PNF Unassembly Combo Set with Kkmulticopter Flight Controller for Beginners (Only Airframe Kit)

drone appears decent quality for the price but the assembly instructions are garbage. drone would not work and the seller was useless to help troubleshoot issue. seller refused to send a replacement part (the flight controller that wouldn't activate/link up to controller). seller suggested I send the whole kit back for a refund, which I did. seller then refused to send a replacement drone when I ordered the kit again.

First, I would like to give this seller a big thumbs up! I reached out to them after I made my purchase and explained that I was buying this so that I would have something to do during quarantine, and they shipped it the next day! Fantastic!Now about the product: There were no instructions, which was fine. Building drones is a fairly straightforward process, especially since they already soldered the ESC's to the board. Important thing for those who have never done this before: Brown is the ground on the ESC's, and when you are plugging them into the flight controller, start with the motor that will be number one and the top, and rotate clockwise when plugging them in.Lastly, the bad: the landing gear is a little lacking in quality, if you plan on just using screws anyways. The holes weren't threaded very well, if at all and I ended up having to glue them into place to last until the better landing gear that I bought arrives. And the Flight Controller is a little unstable, so I would recommend picking up a DJI Naza at some point.TLDR: Great buy for the money, but some areas that you (as the consumer) can improve upon the design.

Product never worked and the vendor does not respond to my return request even after two weeks. Instead they say they I cancelled my return request.
