I found the build of the frame to be a non-event. I had none of the fitiment issues that many have complained about. There were two holes that did no line up but a quick pass with a file and all was good. The camera mount is another matter. RTRyder has the same mount and has been a great help in pioneering the mods necessary to make this mount work. That thread is here if you are interested: http://www.multirotorforums.com/showthread.php?1190-WKM-Quad-and-RC-Carbon-GoPro-mount. You will note in the raw video that it is very jumpy. I noticed after the flight was over that one of the roll control rods had come apart during the flight. I cannot get the control rods long enough and I don't have any spare rods that will work. So I am going to mod the servo mount to lower the servo and allow for shorter control rods. A few minutes with a file and it should be fine.
Flight notes: All WK-M settings are default. I am using 2 x 3S 2200mAh. My 1st voltage warning comes on at 10.5v and the 2nd at 9.9v. The GPS is drifting and I am pretty sure this is a CG position mis-adjustment. The video was flown in Atti only. The motors are RCTimer 2830-14's with 30A Plush esc's and 10x4.5 props. The flying weight is 1.9kg. Note at :56 the motors seem like they loose power slightly and again at 1:56 where the quad started to wobble and lost power. I flew for another minute before I got the red battery warning light. When i charged the lipos, I put 884 and 1117 back in each. They both were at 11.4v when I put them on the charger, but that is not under load. I got a total of 6 minutes flying time. I expected more. Now that DJI has posted their explanation of the parameters there should be less set by the seat of your pants testing. Not a bad first flight but I was expecting more after my experience on my test mule, an ArduCopter.
