If anyone here wants to try to recreate your Sim Copter glory days, I would recommend FlansMod. It’s an incredible mod family that is pinned to the ancient Minecraft 1.7.10 I believe. It has tons of vehicles and weapons from WW1 biplanes to mechs. There are definitely helicopters and I think they have passenger seats.

The whole thing was pushing the bounds of the Minecraft engine beyond reason when it was being actively developed, and has largely been abandoned. Still, I was hosting a Flan’s server to play w/ my kids as recently as last winter. If you can live with the bugs it’s an incredibly fun mod, and a masterclass in Java hackery.

In my experience there aren't many things minecraft doesn't have a mod for -- though sometimes it is a matter of what version of minecraft you want it for. mods at the very least tend to trail the main release version by a few cycles.

While Ride of the Valkyries blares in the background, obviously.
