Throttle Controlled Avionics

Originally created by qfeys and Zenka

Current development and maintenance: allista


TCA is a plugin that enhances the attitude control of a ship by dynamically changing the output of its engines and RCS thrusters. Even with most unbalanced designs TCA maintains stable flight and quick precise response to user or autopilot input. TCA also provides many sophisticated autopilot programs based on this core functionality, including waypoint navigation and automatic landing. It is also fast enough to simultaneously control a whole squadron of ships without much overhead.

Downloads and Installation

TCA requires ModuleManager to work.

If you're upgrading, DELETE the old version before installing a new one. BUT do not delete the TCA.conf and config.xml files to preserve your settings.

If you like TCA you may buy me a cup of coffee to help the development.



First of all, many thanks to qfeys and Zenka for creating the original concept and implementation. Without them TCA would not exist.

And I want to express extreme gratitude to smjjames, who helped me so much with the testing of TCA3 and proposed countless improvements. Without smjjames this version would never have come to a release!
