It takes only a few simple, affordable upgrades for your DX3 Smart to provide many of the same capabilities as radios that cost much more. Just download the free Spektrum™ Dashboard™ app to your mobile device. Add the BT2000 Bluetooth Module (sold separately) to your transmitter. Then, with no additional sensors or modules, you’ll be able to use the transmitter’s Smart ESC compatibility to receive important telemetry data in real time, right at your fingertips — and can also set up warning alarms and enjoy new programming options!
