I added in an ‘idle’ engine.

It’s an engine hidden inside that’s shrunk down, has a power multiplier of 0 and is only there for the sound. I use ‘Activate8’ as the input, and prefer the Blasto BFE300 as it has the best sound. @Tester15

Wait how do you make ur engines sound like that when u turn them off/on sound rlly cool

Re-upload because I accidentally uploaded the wrong video

Here's the plane if you're interested.

Enjoy :)
