I'm guessing the whistle noise isn't an issue anyway, he needs a really powerful propellant to get it off the ground, you could add "auxiliary" sound making units
core designs very important and if you did use narrower core on a fast burning propellant like whistle,it wouldn't be able to expel the gases fast enough, leading to a Cato
