DX2.0 sucks.......

Even though Spektrum is 2.4GHz, you can still have problems if the antenna or throttle cable is too close to the high current wires (power or motor wires, especially the motor wires). It's not so much interference, but RF "wash-out"...enough to make the receiver lose some of the data packets.

And FWIW, I've had a brand-new receiver with an intermittent broken antenna. Would work fine, then just stop working. Had to replace the wire with one of the EXACT same length (very important). Worked great after that.
