Thanks for the information. I will have to take a look at a Pitts, it sounds a little bit like a balance horn, not associated with the balance weights found attached to the leading edge of a Cessna 150 aileron. The one needing airflow to function the other not. I would love to get hold of that article. I have just bought a Jabiru and from what I read, flutter is dependent, amongst other things, on speed, balance and weight of the control surface. The Jab 400 is fast (for its size :) ) and has light control surfaces, I wonder how far the factory took the ASI, and it must be something that the Lanceair folk poked around with. It would be nice to read something that told me not to worry about flutter until 150% VNE or something, it killed the guys in the Yak, both very experienced pilots who would never fly on or near VNE. I would have thought that the first sign of flutter would be a vibration, progressively getting worse, that you would have sufficient time to recognize the onset and slow down.
It’s an interesting subject and I suppose manufactures are not gona tell you what happens after VNE and when…ha-ha. I would however like to know what to look out for and how fast it develops into structural failure…..maybe that’s why they fit a spade to the aircraft, its for digging a hole !!
