    The kid launched one that I got him from the black Friday special, he changed it out to a 38mm, added a bunch of nose weight and launched it on a two grain Cessaroni, flew great (but no whistle).

    This is an old thread....but I've got a Composite Krill Aircraft Katana that has Live Hinges on the Ailerons. That design, and early FiberClassics (CARF) whistled when you rolled the airplane. Air moving around the wing where the top of the aileron was live hinged (surface hinged) but open on the bottom, made a light screech/whistle sound. Maybe that will be one on my next projects......

    You don't have to send the whole harmonica, just the reeds :)

    Of course the JU-87 sirens had an engadgable propeller for ease of turning on/off absolute terror...

    Kazoo's won't work . . . You have to "hum" into them to make them work.

    So, you want a "whistle" ?

    The Galaxy is the one you want, on a fast burn motor. If the motor burns too long, the rocket is too high to hear the whistle.

    What he said.

    If you want something small, a MadCow solar express is great.

    Those were commonly built with a Hemi.

    Yep . . . That one was powered by a 331 Hemi . . . I have "visions" of a 426 Hemi-powered one, with Dual Quads or fuel-injected, with a 6-71 Blower - LOL !
