Could it be the LM3485 is really sensitive to ANY spike over 36v and the TVS isn't responding quickly enough to prevent the spikes?

Another possibility (I'm reaching here); could the high voltage and high currents on the motor leads be inducing a voltage somewhere in the BEC circuitry where it is "unhealthy"? I wouldn't think that the chip would be that touchy.
