Weeeelllllll......
I have tried multiple things to get a Low Power Rocket to whistle, including whizzers on the rocket, and even a plastic whistle with a funnel, no joy.
I have read about High Power rockets with split fins whistling, sooooo.
This rocket has split fins, they are NOT tapered or rounded, just flat. I figured I'd test multiple spaces, so the four fins have splits of 1/8", 1/4", 3/8", and 1/2".
Flew it on B6-4, no whistle. I may try this on Quest Jet D (fins are 1/8" balsa, papered with white glue and triple filleted, so I think they will stay on) with more velocity.
Anybody have any ideas? Wondering if I need to try tapering the forward fin edges, or trying different shapes.
