I am wanting to get a "universal" TX, but don't know what I need to do or what I need. I have a Traxxas Jato 3.3 and a Traxxas slash 2wd. I also have an Axial wraith that I would like to put on 1 TX. What TX is recommended and do I need to upgrade all my RX on them. I am running 2.4 on the slash and wraith and have ordered the 2.4 for the Jato. Any help would be greatly appreciated.
