I have the Realair Turbine Duke, which is an awesome plane but the one problem I have is that I get no audible overspeed warning. I also don't get any sound warning when I reduce power fully with my gears up. All my other aircraft give an audible alarm when I have these conditions. Is it normal, on the Turbine Duke, to only have the caution lights indicate these situations and have no warning sounds? Is there a switch somewhere in the cockpit to turn on the sound for these situations?Thanks

I've been flying the standard and turbo Duke both and have never heard a warning one. Must not be installed?? No, there's no switch.
