We were flying the Ultimate again today and when turning over the middle of the field setting up for a higher speed knife edge, the elevators started fluttering like crazy!

Chris was flying the airplane and reduced speed and the fluttering stopped, (luckly)

I am not sure what all contributed to it. Probably the higher speed was the major factor, so be carefule when doing high speed knife edges.The linkage was tight, but the Hitec 5985 was sloppy? I will be ripping it out and looking at it too.

Jim!
