I got the flash card, updated the radio about a year ago. I switched over to airtronics and put my two flyskys on the shelf. Now my son and I both have crawlers and want to dust these babies off to utilize 4-5 channels. My question might be a waste of time but here it is, for the 6 channel rx do I have to do anything extra? Is the needed programming already installed and I just don't know it? I don't have the 6 channel rxs yet. We want to add wenches, digs, and windshield wipers for our scalers.

Thanks for any help anyone can send my way.
