I also have very bad experience with Yuneec products and services. At first I bought the DJI phantom 1 and having a lot of problem flying it I decided to let go on DJI and bought some other models drone like Walker, and felt it was cheaply built, then came Yuneec Typhoon 500+4k, that I enjoyed the simplicity of flying, but unfortunately, on my first flight, the craft has crashed into a tree and a metal fence, on RTH function, couldn't understand why, I guess the RTH didn't work, the craft was broken in two and the camera and Gimbal went apart, so I decided to rebuilt the whole thing (as an electronic technician) and ordered the replacement craft shell from Yuneec (it would be much cheaper than send back the craft to California from Quebec city Canada) and to be sure I would get exactly the same electrical configuration I bought another Q500+4k, (this time from B&H) Yuneec would not provide any schematic diagram of that drone. So after a week of rebuilt, my crashed Typhoon was ready to fly, and it did well for approx. 5 flight, and at the last flight, only 3 motors would spin, so I've open the cage of that motor, and found one wire going to the motor controller was broken, and the socket was also broken, so I decided to solder the 3 wires directly to the board, and that was fine ,it did work for a few flights, and again that same motor stop to spin, open it again and found one IC has burned on the controller, got in touch with Yuneec, after many attempts and was told that board was not available!!!! isn't that ridiculous I now have one Q500 that's grounded, useless.
Then came the Typhoon H, it was very impressive, and was stupid enough to go ahead and buy one, but I've enjoyed very much the few time I was able to fly that drone, for last week while flying in an open range, suddenly the H would spin on itself at approx. 100 feet in the air, I was afraid it would crash, and used the RTH function and it landed safely, upon inspection I found it had lost one side of a propeller!!! so there was only half propeller working on that position (propeller A) and as stated in the manual, the drone would switch automatically in a five rotors state if a problem occurred, and it did well. What surprised me, when I replaced that broken propeller ( forgot to mention i'd already checked if it was in good condition before flying and there were all in good shape no cracks ) and try to fly again, and as soon I hit the power button, I got a warning not to fly for it was in the state of 5 motors!!!! tried a second time after shutting down and turning it on again, and all the 6 motors started to spin, so I thought it would have reset to a 6 motors state, I push the throttle stick up, and suddenly the craft felt on it's side and broke another propeller.
Needless to say I was very upset, phone the lousy Yuneec service dept, and told them of my bad experience, and was told to send the craft to California and again told them I wouldn't do so, for it's to expensive sending goods from here to USA. Why at first that darn H wouldn't reprogrammed to 6 motors state, it's useless to have that option if you're not able to use it again... sent another e-mail to Yuneec two days again, and waiting for a positive reply, worst of all, I received yesterday two ordered batteries ($200.00 a piece landed here) that I don't know when I'll be able to, try.
Sorry for my long story and my bad English. Thanks for reading.
