Who is this for?

This information is not intended to serve as a guide to developing helicopters from the ground up for microsoft flight simulator. This information would be most useful to a developer that already understands the concepts involved with installing, developing, and modifying helicopter add-ons for flight simulator. Users of this information should already understand how to modify text files, install development software, and access the flight simulator SDKs.

Many developers, even gifted ones, are inclined to use the default 206 flight dynamics if they feel that they can not improve upon them for their add-on. I hope this information helps you expand your bag of tricks, and assists you in developing your own personal flight dynamics style.

Over the past 8-10 years I have been slowly building a working knowledge of the Helicopter flight dynamics configuration for Flight Simulator. The following collection of documents is my attempt at sharing both the general and detailed information I have uncovered during that time.

The subject of 206-based helicopter flight dynamics in flight simulator can be approached from two different angles. You can choose a desired behavior (or topic) and learn a little about which parameters are related to it. Or you can look at each parameter, its function, and how it relates to other parameters.

The information in this collection has been organized in such a way to help make that easier for you.

Good Luck!
