Hey buddy,
You can get a program card for it:

You can change the settings without it. Get the DEX210 manual here:
http://www.team-durango.com/pdf/manu...rt%20Guide.pdf and look at page 6 onwards. Also worth following the throttle/neutral/brake setup too, else it may not be fully calibrated for your transmitter.
