I noticed on my 2218X Receiver there is a Male Plug location on the side of the Receivers Box and I noticed on the Traxxas Link 2.4GHz Transmitter in the battery compartment there is the same style Male plug in (it is located next to 4 Battery Holder in the battery compartment).
I am curious as to what the Uses are for these plugs as I have not been able to find anything in the manuals etc.
If you do not know what I am talking about I can get a Picture of the TX but I have the RX Box all waterproofed so I would rather not open that if possible.
I bought the Traxxas Link TX 2.4GHZ Separately as I received a TQ3 with my T-Maxx 3.3 Upgraded Truck so it originally did not come with a Traxxas Link 2.4 GHz TX and RX but I thought a 2.4GHz TX and RX would be a much better Setup with of course a whole bunch of upgraded features.
