How can I diminish the sound of the cabin heater on the piston Duke? It is too loud to me.
You can hear the heater? I've never heard it. It's audible in the Baron if I recall correctly, but I've never heard anything in the Duke.
The cabin was noisy, I shut off the heater and the noise disappear. Conclusion?
That's the fan I guess..
The heater itself does make a rumbling sound, as a real gas heater does.
Turn it off.
