E-Soar MAXX - Pro template for F5J competition

E-Soar Maxx is an advanced template for F5J electric sailplanes with 6 servos + ESC. It's based on E‑Soar Plus, but with additional options specially for F5J competition.

New in version 2.1 - crow aware trim

Building on the success of earlier versions, 2.1 has a couple of major ease-of-use enhancements.

The first is a continuously variable ('crow aware') trim for crow brakes. This allows you to trim out the brakes precisely, throughout the full range of crow. For background info see article 'Crow aware adaptive elevator trim'. Note that the Lua script is not needed with this template, since Ethos 1.5 provides all the necessary facilities.

Secondly, all pitch adjustments - including crow-aware trim and motor compensation - are made with the regular elevator trim. This makes the trimming procedure much more intuitive.

Finally, for V-tail setups there's an option to adjust V-tail diff.

Note: The sister template E‑Soar Plus is better suited for sport and younger pilots as it offers two additonal arming options.

Competition mode

Competition mode is unique to E-Soar MAXX and offers the following additional features.

30 second motor timer
