Flight Counter

Small and simple but handy flight counter for your transmitter made from request.


How RCT Flight Counter works

Functions is simple and app is easy to use. You set a telemetry control to get the flight that is active on condition you want, here’s some examples:

  • Flight Battery voltage over 10V for 60 seconds
  • RPM over 1000rpm for 45 seconds
  • Relative altitude over 10 meters for 10 seconds
  • Rx-voltage is over 3V for 120 seconds

It’s really your definition of what is a “flight” that set’s your telemetry control.

Featured Functions

Simple functions for a simple app:

  • User set activation switch
  • User set minimum time for the switch before flight counts
  • Possibility to adjust flight count

Note: RCT Flight Counter works in DC/DS-14/16/24 with firmware 4.22 and up


In short: Copy the RCT-FlCo.lc (or .lua, the .lc is memory-optimized) file from github here to your transmitters Apps-folder, copy the RCT-FlCo.jsn file from Lang-folder to Apps/Lang-folder on your transmitter. Head on to “Applications” -> “User applications” and add the app. Guide on installation of Lua-apps available here if you need some more in-depth guide.

Setting up and usage of RCT Flight Counter

After installation open the app and you are presented with easy setup with only a few options:


Settings are simple. First select the telemetry control (MX-switch) you want to use. Then set the minimum time this switch needs to be active before flight is counted. On the last line you can adjust flight count to desired value between 0 and 10000 if needed. (Note that this value does not update in real time, you need to close the form and re-open for updated value)

In the example above I have flight counter working from switch Sa, switch needs to be active for 45 seconds before flight is counted. Current flight count is 217.

Add RCT Flight Counter to your main screen

You can add RCT Flight Counter to your main screen too, go to “Timers/Sensors” -> “Displayed Telemetry” and add the “RCT Flight Counter” to your main screen:

After that you have the counter on your transmitter’s screen:


Like a Donald in U.S always says, “So easy. Trust me.”
