Track your RC model’s telemetry real-time on one easy-to-read display!

*This app requires you to have:
- A DSM2™/DSMX® RC aircraft transmitter
- An RC model equipped with a data port
*Telemetry-capable DSM2/DSMX receiver
*Spektrum Air Telemetry Module
*Spektrum Telemetry Sensors
- The Spektrum STi Telemetry Interface

With this app and the Spektrum STi Telemetry Interface connected to your iPhone, iPad or iPod Touch, you can receive data directly from your RC model’s on-board Spektrum™ telemetry module. This allows you to monitor vital information like:

-Engine or motor RPM
-Engine or motor temperature
-Flight pack voltage
-Receiver pack voltage
-Signal quality

All the information is presented in an easy-to-read display that even non-modelers can comprehend. You can also program the STi app to alert you whenever a telemetry value exceeds certain limits you define.

Best of all, you don’t have to have a Spektrum transmitter with built-in telemetry to use it. Anyone with a DSM2 or DSMX transmitter can enjoy the advantages of real-time telemetry with the Spektrum STi interface and app. That includes modelers who fly JR®/DSM® transmitters or transmitters equipped with Spektrum DSM2 modules. Even if you have a Spektrum transmitter with built-in telemetry, this is a great way to let a friend keep an eye on model functions while you focus on flying.

You can purchase the required Spektrum STi Telemetry Interface (SPMTR1000) from your favorite hobby retailer or directly from

Customer Reviews

Please improve it!

I use this quite a bit to analyze heli performance, so I would love it if the bugs get fixed and improvements made. The bug I fight the most is opening 3-4MB files. It generally won't appear to open them unless a smaller file has been opened previously. Once it does open, all of your previous attempts show up.

A very nice change would be to title the flights get titled according to the imported file name versus time of import.

An obvious visual bug is the airplane symbol on the replay map tries to point in the direction of flight, but constantly flips back its default direction. Fix it or eliminate the feature.

New interface makes everything so much easier

Already ordered gps sensor...cant wait...other changes are amazing...way to go Spektrum team
