Spektrum Telemetry

Spektrum™ telemetry technology makes it possible for you to get real-time information on your model's battery voltage, motor rpm, motor temperature and more. Many Spektrum transmitters feature built-in telemetry data receivers that let you view this information on their LCD screens. You also have the option of monitoring telemetry using the Spektrum STi™ app for the Apple® iPad®, iPhone® or iPod Touch®.

Spektrum is releasing new telemetry sensors and accessories all the time. To give you a feel for what a difference Spektrum telemetry can make, here are some of the most commonly used telemetry features most Spektrum users take advantage of:

The Spektrum™ STi™ Telemetry Interface for iPhone®, iPad® and iPod touch®

The STi lets you transmit vital info from your model's on-board Spektrum™ telemetry module directly to your iPhone®, iPad® or iPod touch®.* It can also be programmed to alert you when any telemetry value you're monitoring exceeds limits you define. It's a great way to keep tabs on your model if you're flying with a DSM2™/DSMX™ Spektrum or JR®/DSM® transmitter that doesn't have built-in telemetry. Even with a telemetry-capable transmitter, you can use it to let someone else watch telemetry so you can focus completely on flying.

*Requires the free STi app. Compatible with iPad, iPod touch (4th gen), iPhone 4, iPhone 3GS, iPhone 3G and iPhone.

Battery Voltage

Never again will you have to wonder whether or not you have enough voltage to keep flying. Being able to monitor voltage will also help you detect a worn out battery pack before it prematurely ends your flight. The telemetry module is plugged into the receiver and will automatically relay receiver voltage. A separate sensor for tracking main battery voltage in electric aircraft will be included.

Temperature

Is the engine running too lean? Is there enough airflow reaching an electric motor? Is my battery getting too hot? Get real-time answers and take action well before damage occurs.

Signal Quality

Spektrum telemetry modules keep tabs on the quality of the signal coming to the receiver and send this information back to the transmitter where it is represented on the LCD screen using a familiar "signal bar" scale.

RPM

Pilots can use the RPM telemetry data to check the effectiveness of new mixture settings, new battery packs, or perhaps a new propeller/motor combination.

RPM sensor

Airspeed

Measures airspeed from approximately 2 MPH to 350 MPH

Airspeed sensor

Altimeter

Measures up to approximately 1000m above ground level. Advanced software allows processor to compensate for variations in temperature
