RE: Whiplash RIP
C4F, One of the cruelest realities in our universe is that screws aren't self tightening, they always work loose. Sorry for your loss, but thanks for the wake up call. The problem is that we are all pressed for time to have fun, and don't want to do the boring job of checking everything. Of course, there are certain things that go wrong that routine checks won't reveal.
I don't know anything about Whips, you said you had flutter AS USUAL at full throttle?
