RE: What does flutter sound like?
I don't know what flutter sounds like, but an interesting sound that is usually made right afterwards sounds something like "oh damn!"

BLE,
More often than not, a still picture, movie or video is worth a thousand words. You choose the right flick to show flutter!
Thanks,

Hi.
While flying my Hobbico Hobbistar 60, I've done a couple of high-speed (well, high-speed for a trainer) passes and another pilot said he heard flutter. All I heard was the prop and engine.
1) what does flutter sound like?
2) Is there a way to isolate it so I can be sure that is what I'm hearing?

I've got the same plane that makes the same noise you are talking about. I've flew it with that noise well over 100 times. It always happens in a high speed nose down atitude. Everybody said it was bad flutter. Well it isn't, its the front nose cheeks vibrating against the big long aluminum motor mount on that particular plane.

- It may mask the sound of real flutter.
- It indicates excessive vibration of a part
- It will cause excessive wear of the cowling
Do you have anti-vibration mounting in place on your cowling? e.g. the tubing over the screws, etc.?

Which I would immediately correct so as not to happen again because...
- It may mask the sound of real flutter.
- It indicates excessive vibration of a part
- It will cause excessive wear of the cowling

Ahhh, I ain't to worried about it. If I get tired of listening to it I'll just cut the cheeks off of the plane.
No anti-vib stuff on it, the plane comes with everything mounted solid on this particular model.
I fly this plane full speed every time its up with no problems at all. If it quits, it quits. I've been wanting to put that engine in something else anyway.

one day soon you are going to fold the wing up on that trainer airplane doing full-throttle pull ups.

I've also had some problems with screws coming loose on the engine mount and the engine back plate. There must be a lot of vibrating going on up in the air.

Hi, My Four star 120 with a 25cc toro suffered from flutter last week. I went straight up with it until it couldn't climb anymore, pulled the throttle down came straight down with it and both ailerons fluttered!! It sounds like the trailing edge of a kite flapping on a windy day. I lost control of both my ailerons. So I had to land with the rudder! Found out one servo stripped and the other servo mount broke loose from the aileron hatch. I was lucky to land it in one piece. I will now beef up the aileron hatch mount and use metal geared servos. Lesson learned!

LOL yeah, thatS about right. only diffrence is number 3. but its a toss up between yours, and or W T F !?
1. The loud buzz others have described.
2. The bang as the aircraft (minus some critical component) hits the ground.
3. The "OH Sxxx" of the unfortunate pilot.

Normally when you here it & say W T F it's T F L.
