With my setup Saito 100 & APC 15X4 I stopped tuning at 9800 on the ground. The prop went supersonic in the air but air speed was probably less then 40 mph. With the wind across the surfaces, maybe 55-60. Maybe. There is no alop in any of the surfaces and all of the normal stuff was done, don't think I overlooked anything.

Flutter is not something I am real familiar with as the only plane I have that really flutters is a little Ace Ultimate I seriously overpowered but when it occurs on that plane you see some very high speed surface movement and you can hear it too. On the showtime it occured with the plane maybe 100 yds. away and I could see the ailerons but didn't notice the tail. When I got to the plane the tail was torn up but the ailerons looked fine. It started raining just as I got to the plane so as I said I didn't look it over very well. I will check it out tonight though and let you know what I find.
