Recently I was breaking in a new set of batteries by running 5 minute, less than half throttle runs in the Integral on my side patio. I tied my fuse to the gas pipe with a rope over the fuse just forward of the vertical stab and under the horizontal stab back to the pipe. I did not have the wings attached and I left the canopy off to read the ammeter.

I was surprised at the back and forth movement of the fuse in yaw at about a half Hertz rate even at this low throttle setting. I assume this was due to the spiral slip stream but I'm sure the surrounding objects contributed. It sure would be impressive to see if this would be eliminated with the contra drive. Maybe I could push and pull some decent corners if it would.
