QWinOutDIY 2.4G 8CH KK V2.3 F450 Frame RC Quadcopter 4-Axle UFO Unassembly Kit RTF/ARF Drone (KK FC Version)

This one a replacement the first one had some issues they resolved it quickly and working as described very upgradable

I bought for my honors project and it was fun to build it but it has lack of instructions

DearHello, you will find attached the letter of complaint. By this letter, I come to inform you that the drone kit that I bought from you malfunctioned, I followed the instructions from the link <https://youtu.be/BssJG1M-X9 and the tutorial > present in the kit on a badly printed sheet.Unfortunately the motors are activated but the flight controller which stabilizes the drone during flight does not activate, as well as the second lever to the right of the joystick, for a month of testing and a few weeks now.In addition, what I noticed on the site there are 4 propellers, it must have had its original packaging box and the instructions but all that was not there except a badly printed sheet to show how to calibrate a drone and other way to turn it on.

This kit seems like a great introduction to quadmotor RC's. There are no instructions and the you tube instruction videos (make sure to read through the Q&A to get all of them) lacks any instructions about orientation of wiring, paring the controller to the board, tuning the response, etc. I built a lot of stuff, so I could figure it out, but beginners would find it difficult. On the trial run, found the controls erratic and highly sensitive. I first scooted around the ground to get a feel for the controls before I lifted it into the air, even still it leaned too far to one side and the propeller hit the ground and shattered, which flipped the device around and shattered another propeller. On my second flight session it crashed and shattered more blades (even in the grass). The copter was very unstable with the initial settings. I advise using a 4-point tether until the controls are tuned. Buy lots of extra propeller blades until you get it tuned. You can find manuals for the KKmulicontroller V5.5 flight controller, and the Radiolink RC components on the web that explain how to tune it. I give it a 2 star for product friendliness (have to do a lot of you own research on the parts). I give it a 4 star as a group of components for the enthusiast who wants to research and learn how quadcopters work.

Easy to Assemble ! Worked great

My son had a good time putting it together

I put together the quad copter in one evening, but then I had trouble figuring out the wiring, i’ve watched as many videos as I could find and I still can’t get it to work, I’m concerned I will never ever get it to fly

Esc smoked to one of the motors then smoked the motor in tear down. mister Chinese on the soldering job left a piece of floating solder which shorted the esc not to mention while figuring out why all this happened the motors just kicked on blades went everywhere one stuck in my foot the other in my arm. 14 stitches save a trip to the ER run..... ps controller board is so outdated it is a relic
