For me rat biplane is one of my favorite rat upgrades, but the only thing that is stopping me from using it is that I have to disable certain sound settings to use it without the sound it makes getting really annoying.

A great way to deal with this is maybe a setting in the config to lower the volume of the rat biplane. It would really help out people who have lots of rat biplanes transfering items all at once.

the main problem is that the sound is stereo, meaning that the sound didnt fade as you got further away from it. Ive fixed the sounds to actually do this in the upcoming 1.19 version, so it will no longer be an issue
