Well I just sprung for the TSM receiver $35. My wife was upgraded to a differant phone, so I got her old Iphone 3S. I Installed the Traxxas software on it. When I hooked it to the docking base, it updated the docking base, or so it stated. I guess to handle the TSM receiver. The old Traxxas link software I had used before on this phone, didn't have the TSM inside it. I'm experimenting on a 3908 BL E-Maxx. When it was done updating, (about 3 minutes), turn the truck off and on and the TX and restart, the drving affects was on the Traxxas link, showing the TSM adjustments. It just said there was no TSM receiver present.

Just to mention, this is the 2.4Gb Tqi without the bluetooth module. But the Iphone does have BlueTooth. So I guess when I get the receiver, we'll see if it all works like they claim.
