I'm new to Traxxas and have just purchased an E-Revo Brushless with TQI radio.

(1) What parts do I need to buy to use this radio?
(2) And do any of the reading's on the app work without purchasing additional parts?
(3) Finally, how difficult is it to install these parts? I.e does Traxxas provide any instructional manuals or video links showing how?

Thanks in advance to anyone who takes the time to reply :-)
