Max Current Display

Small app for those who’s ESC does not provide max current as a telemetry value and are too lazy to open logs. or just simply wants the value on main screen. Done due a request by a user on Helifreak-forum.

Featured functions

  • Selectable sensor
  • Selectable reset-switch
  • Reset possible if no sensor detected or sensor-value is zero

Available for DC/DS-14/16/24, requires firmware 4.22 or higher. App does not run with older firmware.


In short: Copy the .lc (or .lua, the .lc is memory-optimized) file from github here to your transmitters Apps-folder, if there is a translation file copy the .jsn file 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 MaxCurrent

Settings are simple. Select correct sensor (your current-sensor) and assign a reset switch. Reset-switch resets the max current value to zero is there is no sensor available and switch is used or if sensor-value is zero and switch is used. You can for example use a telemetry-switch to this to have max current reset automatically.

After this go to “main Menu” -> “Timers7Sensors” -> “Displayed Telemetry” and select the new telemetry windows “Max Current” to your mainscreen:

After that you have a new window “Max Current” on main screen:

In the picture above my selected sensor (Test Sensor 1) has a value of 5434, since this is the biggest value so far the Max Current also shows that. If sensor value goes down it could look like this:

Max Current is 5434 and current value is 175.

To reset Max Current the switch needs to be used and current value needs to be zero or sensor needs to be powered off.

Really simple, enjoy :)
