OpenTx

OpenTx is a highly flexible open-source operating system for RC transmitters. The project is directed by a group of talented programmers who are also active model flyers. OpenTx comes pre-installed on the FrSky Taranis.

Applications

OpenTx is suitable for a wide range of applications: at the simple end, it's great for multirotors where most of the work is done in the flight controller. At the other extreme, OpenTx's ultra-flexible mixing make it ideal for F3X sailplanes.

Designing setups for maintainability

OpenTx's power can be a double edged sword. In inexperienced hands, setups can end up being over-complex and difficult to adjust. However, it's just as easy to create setups which are elegantly structured, and simple to adjust. One of my goals with this site is to explain how to achieve this, using techniques which are unique to OpenTx.

The results can surpass what can be achieved on other systems including Jeti, Futaba etc.

Pre-defined setups

If you want to get going quickly, then you might want to try one of my sailplane setups. These have proved popular for both sport and competition pilots as they are full featured yet can be freely customised. Full documentation is provided.
