Radio Glitching
My brand new E-MAXX 3905 is having radio glitching issues. It's running on 27.195Mhz (green) crystals. The battery packs were fully charged and the transmitter batteries are all brand new and tested at a good 1.46V a piece.

It works fine as long as the antenna from the transmitter is within a foot of the truck's antenna. Anything further than that and it'll glitch and get worse as I get further away.

I had a spare TQ-2 transmitter which I know worked fine from my old Jato, so I swapped the crystal from the E-MAXX transmitter and had the exact same outcome with no improvement. I also re-calibrated the ESC verifying that the throttle and steering trims were set at 0 on the transmitter.

I called Traxxas support and he suggested taking the truck to a different location first to rule out interference. I don't think it is interference because I can turn the transmitter off and it'll immediately stop glitching and sit there with the green light on the ESC shining solid green. It is only glitching when the transmitter is powered on.

I'm leaning towards a bad crystal or a bad receiver since the other transmitter (which I know works) had the same issues when I put the crystal from the E-MAXX transmitter in it and tried using it.

Does anyone have any input?
