[edit] Known issues
The tail belt can cause a static electricity discharge, which can reset the flight electronics and cause temporary loss of control. A number of methods, including grounding the boom and belt to the battery 0V, or spraying the belt regularly with silicone grease, are believed to mitigate this issue.
