AR.Drone ~ "My Drone Won’t Take Off"

004.CRWWell, I experienced that [to my surprise] after replacing the bushings in my AR.Drone with bearings as described in this blog article. It looks simple. It is simple; but, one must be careful. I thought I was being so, but discovered that I had apparently made a mistake along the way—my drone would no longer take off. “My birdie would not fly.” I tried everything:

  • Reset the drone
  • Returned to default settings
  • Flat trimmed multiple times
  • Tried both hulls
  • Recharged battery
  • Disconnected battery
  • Check the position and rotation of the gearing and propellers. The 4 seem the same. I find nothing to slow the left-side down.
  • Checked connections of all boards
  • Waited overnight
  • Tried all the available apps
  • Replace the bearings with the original bushings
  • Switched propellers [to left for two right]

About 14 hours later [this morning]—the problem persist. I opened an thread on Ar.Drone Flyers Forum and continued my research, using the Internet. At this point, I surmised I had a propeller problem and did not know how to sort it out. The answers seemed to all come at once—the forum and a key Internet point-of-contact. Without asking “where are the markings.” I found a “A” on two props and a “C” on the other two. I then found a drawing with these letters adjacent to the props. I took that as a map of how things should be. Here is a picture of my drone, top shell removed, with the letter mapping as I saw it. BTW, the “A” stands for “anticlockwise” and the “C” for “clockwise,” as in rotation. The propellers should be mounted as follow: motor 1: “C” motor 2: “A” motor 3: “C” motor 4: “A”.

Now, if I had looked again at the  “Replace AR.Drone propellers, shafts & gears video,” I may have saved myself grief. Actually, I viewed it [and all of the Parrot Repair Videos] before. My thinking cap was elsewhere.

I carefully laid to props aside so that I could put them back as they were. Well, that did not work. I switched at least two of them. Oh well, I ‘m flying again. I hope this article serves a purpose for another flyer. Thanks to the forum members for their help. Happy flying…

    1. …and computers Wayne. I learned a lot since 1980 about patience in the face of computers with no universal OS and then the growing pains of the Microsoft experience. Thanks to my kids, born years before, I was prepared for that experience. Now, I’m really ready…

      Thanks and be blessed.
