The application RC is especially for model aircraft who are interested in saving the measurements of their ACUs batteries, models, their costs and recording especially FrSKY telemetry (However, it is possible to save any telemetry if you follow a few principles of the uploaded csv file). You can use the application as it stands and runs. It's free, for now :-). I do not bear any responsibility for your uploaded data responsibility. Your data will NEVER be passed on to a third party.
The application is intuitive and easy to navigate after a while. I'm gradually upgrading and adding new features that I either need or you've written about. All in your spare time, so if you would like to support this project, you can :-)
