    Just the Bluetooth module. That's what will connect to your tqi receiver via the transmitter and the traxxas app on your phone.

    Just know that if you change radio or receiver to another brand, you lose that feature.

    Duly noted !,
    would be more efficient to share the link for reference i guess.
    There are many ways to accomplish what you are asking. But may depend on your full plan of upgrades. Or what your install skill level is. The other two parts can be helpful, but not required.
    Also. You may want the telemetry module if you have additional addons planned later.

    Volt,temp,incline meter on phone

    I used the three parts listed above. The temp/voltage sensor is really the only other part besides the 6511 blue tooth module you need. But I found the battery adapter made a clean connection to the receiver. And the little temp sensor holder makes a solid mounting point on the motor for the temp sensor. Everything works perfectly with my Iphone 5S. Love it. Use it every day!

    Speedo and tach will NOT work with the above listed sensors. The TRX4 would require a flywheel sensor as well as a gps unit for those functions. You donít need those on a crawler anyway.

    Lets hope traxxas puts out an update for the $100+ LED light kit for the trx4/sport to utilize the light switch on/off clearly displayed within the app.
