This app is actually just a repackaging of the Anysense telemetry screen found on the Anysense website. Unfortunately, it seems that this app is not supporting OpenTX 2.1 out of the box.

Here you can download the upgrade to OpenTX 2.1, that will also run on 2.0, by means of the AppMan, wich comes as part of this delivery.

  • Just install it, and the anysense app will pop up as an extra app in the AppMan menu.

After unzipping the received installation files to your SDCard, you can install an example model to check out the App by using the "restore model" feature. Go to the Model Selection Screen (push "MENU" once), go to an empty slot, long press "ENTER", and select "restore model". Then select the model "20-AppMan.bin" if you are on OpenTX 2.0, and select the "21-AppMan.bin" if you are on OpenTX 2.1. 

Make sure you activate the AppMan model by long press ENTER again, and choose SELECT.

Press EXIT until you are at the home screen again, and long press PAGE to enter the AppManager, and select the "AnySense" App.

The JustFly App is thé timer and altitude logging App.

This basic version will start in the graphical mode, showing a life graph of your altitude.

There are two timers, a session timer and a flight timer. Both will start at the first pull and return of the start switch, defaulted to SF. Next time you shortly pull the start switch and return it to up, the flight timer is stopped, and waiting for your next start.

If you keep the start switch pulled long enough, it is assumed that you want to do a direct restart. The current flight is stopped, and at return of the start switch to the up position, the new flight is started.

A flight can be cancelled by pressing the "ENTER" button. This will prevent a valid score time to be logged, and puts the App in start mode for the next flight.

If in start mode, and pressing "ENTER", you will end the session. A score card is shown.


The score is your time of any valid flights added together and divided by the maximum score you could get. By moving the throttle stick up, you can adapt the best time possible to the best time actually flown in your round, and get your relative score.

So if you flew the best time, your relative score is 1000.

In order to restart, you can either push the "MENU" button, or pull the timer restart trigger. You cannot accidentally erase the session flight data, because you first need to check the results before you can restart the session.

By pressing "Enter", you can cycle to the next results view, which are the flight logs. You can review any flight by selecting it from the list on the right side with your elevator stick.

If you do not want the altitude graph, but the flight timers to be shown during the session, you can use the "ENTER" key before the session start to change views.

The EngRev App is developed to support users of a special motor controller, allowing reversal of the engine direction by a separate servo signal.

This App was designed around the Turnigy Seaplane 40amp ESC with Reversing Switch.

In the setup screen for this app, you can set up the proper servo output to be used (defaulted to the first free slot), and assign a switch for changing engine direction. you can set the throttle level above which engine reversal is blocked, but to prevent damage to your motor using this ESC controller it must be defaulted to 0%.

Be aware it uses the Throttle stick as input, so if you have set up special mixes to control the motor servo by other means than the Throttle stick, this App is not for you!!

This app will create some mixes and logical switches, which can be removed by the app if you no longer need it.

An example of the setup page is given here:

  • Line 1, no settings, just for info
  • Line 2, servo output selection. You can only select free slots, so remove another mixer line first if you want to use that slot
  • Line 3, Direction info and assignment of a switch to use for switching direction. The app comes with no switch selected, and the engine will reverse each time you reduce the throttle to zero. You can only assign a different switch when the throttle is below your switch Active level.
  • line 4, To set the level for the direction switch to be activated. If you know your controller can handle a 10% throttle and reversal without damage, you can instantly reverse the engine by moving the selected switch when you set this level to 10%. ( good for boats and cars )
  • line 5, You can remove all adaptations to the model setup by selecting "yes". There is no further warning when selected!

The standard voice countDown for timer 1 and 2 will call 30 s, 20 s and then from 10 seconds down every second. For precision landings it can be a great help to have the countdown in seconds start earlier.

That is just what this little app does: it installs a second countdown on top of your existing countdown for one of your timers. You can specify the start point for the countdown, and for which timer you want the countdown.

Nice feature is that you don't need to check with your normal timer settings. It will simply skip the second call if the timer is already calling it, so no double announcements.

If you have a timer counting up instead of down, it will call the seconds after start until your set limit.


Example screen:


  • Line 1, selection of timer to add seconds announcements to
  • Line 2, start of countdown, or end of count up. This is automatically detected based upon the synced timer settings.
  • Line 3, shown if the settings have just been added, and a restart of the transmitter is recommended to make sure the script will function correct
  • Line 4, You can remove all adaptations to the model setup by selecting "yes". There is no further warning when selected!

This is a very usefull and handy little App thats saves a lot of time. It allows you to change the order of your mixes and servos by just selecting the mix you want to change. It is part of all standard Models, but here you can get it as a separate App.


Imagine you are in the field and want to try someone elses plane with YOUR setup or another plane with a different setup. This is what your mixers and outputs screens could look like:

But the plane you want to fly, for some reason, has:

  • Ailerons on channel 1,
  • Elevator on channel 2,
  • Throttle on channel 3.

So you now have two options: rewire the plane, or change the mixers assignments. Both a lot of work.

Not with this app. from the home page, long press PAGE, and select the ServoOrder App:

Youll get an overview of the used mixers for outputs 1-9:

select the servo output you want to shift,and shift it:

and that's it!!.

Check in your openTX screens if everything went fine:



We hope you like it. Have fun and

This is where it all started.  The only free download :)

This script will allow you to prevent a script from running until you click enter. It allows you to manage multiple scripts on your transmitter, and select which one to run without having to connect to a pc to change files.

It is extremely useful for 2.0. In 2.1 you can do that in the telemetry screen as well, but not as quick.


Although this is still a useful little script, it is not that userfriendly to setup.


With the AppMan you can achieve much more. You can manage all your apps in one user interface. Start, stop, select, etc.


It comes with the Basics App as part of the package.
