Traxxas XL 2.5 esc + spektrum 2.4Ghz not working

       Remove this ad - become a site supporter!
I have a brushed 1/16 e-Revo that came stock with the TQ 27mhz radio. I bought the Spektrum DX3c tx/SR 300 rx combo as my first upgrade.

The problem is that I cannot calibrate the XL 2.5 ESC on the e-Revo with this rx. Traxxas tech support tells me its a Spektrum problem. Spektrum tech support tells me its a Traxxas problem. Sigh. When I reconnect the original 27mhz rx, I can calibrate no problem.

Luckily my local shop is very helpful. We tested with different 2.4Ghz rx's, and none enabled the ESC to be calibrated. We also swapped out my XL 2.5 with a new off-the-shelf XL 2.5 esc, and it too could not be calibrated. Last ditch we connected the VXL3m esc, and finally the calibration works.

Long story short: it looks like the Traxxas XL 2.5 ESC is not compatible with Spektrum 2.4 Ghz rx's. If anyone out there has this combo working, can you please let me know what it took to get it working?

Otherwise I think my options are to either return the DX3c and stick with the AM radio (boo), or shell out an extra $180 on top of the $130 i've already spent on the radio, to go with the brushless/vxl3m combo (double boo).

What to do?

EDIT: I wound up getting a decent deal on the Velineon 380 brushless/vxl3m esc combo, so while my problem isn't solved, at least I have a workaround.
