Twotter Revived

Twotter Revived

Description

Twotter Revived is a free, community-built overhaul of the Aerosoft Twin Otter (MSFS 2020) for MSFS 2024. The goal is a faithful recreation of the aircraft, replacing stock sim systems with custom code where the sim falls short. Engines, electrics, radio navigation, and countless other systems are simulated in depth and interact with each other. The flight model has been redone and refined with invaluable help from CanadianCaptainMoustache.

Introduction

By now, this is probably what the modding community would call a "Total Conversion". Almost every system in the aircraft has changed, many have been replaced and redesigned, and even some core sim systems had to go in favor of custom implementations.

This is a test version. Please flag any issues you notice. I try to make sure the releases published on Hangar Addons and flightsim.to don't contain any blockers or stoppers that would keep you from flying, but bugs cannot be avoided, and if you find one, please return it to its rightful owner.

If you run into issues or have questions, contact me here or on Discord: aurel#3010 (if you're active on Discord, we most likely share a few flightsim servers). If you know about the aircraft IRL or aircraft development in MSFS, I'm especially grateful for your input and suggestions.
