It was a interesting day at the local park. I was flying the Wide-Body Arrow and towards the end of the first flight the plane sort of went out of control. As it rolled over I thought to myself, "Well there goes another one." Then, I was able to get it to level out, turn around and bring it in for a half way decent landing. That is the flight video below.
After checking all of the parts and making sure the battery wasn't flopping around, I could not find a issue. I thought maybe it was a strong gust of wind so I tied it again. After about a minute of flying just fine, it turned up and over and started to nosedive. I was able to get it back under control and land it again.
Then something unusual happened, I was approached by a man, whom I did not know, that had a Quad and asked if he could try and take some video of my plane in flight. I explained to him that I was having some issues. He asked if he could video the next flight. I said, "Sure." Nice guy and showed a lot of interest. He asked a lot of smart questions and in the process of answering his questions about the plane, just before I launched, I discovered the issue. He asked me what makes it turn and I tied to show him the Elevons move and discovered that I had a sticking servo that would bind-up at the far end of movement in both directions on one side.
So I came home and changed it out. Now I'm going to get up early and try this again.
