I have them on a couple planes but the sound seems to stop after about 75 mph, I have them mounted where they recomend, let me know if you find a spot where they work better at higher speeds, I suspect it depends on the airflow of the airfoil but they seem to act the same on all mine and they are 3 different airfoils, I have them on my Funtana, Uproar and PC-9, Brant

I had them on an Uproar 40, and I have the smaller ones on a .25 Modeltech Extra. Both have them under the wing just behind the leading edge. Do yourself a favor and open up the orifice. You will have better sound output if you do so, and it also increases the leading edge. Also, the longer you make the tube, the deeper and louder the whistle will be. This also helps to increase your speed threshold as well.

Once you get them installed, got up as high as possible, cut your throttle, and dive in on the flight line, you will get lots of looks and cheers. All the folks at my field love it when I fly.

I lost the Uproar this fall in a streamer combat collision. I won that collision however, the Uproar has great single wing stability.

If I recall correctly they have diffrent ones for a variety of speeds. I have the high speed ones and they work fine at the 90-100 range.

65 mph is defiantly high speed for a Cub, it's about landing speed on a few of my old jets.

I just bought a Nerf Mega Howler looks like a yard dart thing that you throw, it has 3 very similar plastic whistles in it for $8 at Frys Electronics they should be at the toy stores allso. I havn't tried them in a plane yet but they should work the same and they weigh much less.

Yeah, They also had a wicked cool siren for the Stuka. The whistles work great just like they say at the speeds they said.

Heres the link: http://www.i4cproducts.com/

Photos on the site show where some people mount this but there is a problem with it. They need a direct flow of air and the way air flows over and airfoil, you could be making many holes for trial and error to get them to sing. So to eliminat that, the plane I installed mine on had the wings cliipped and the outer edge was flat. it is now very loud and noticable.
