Re: Prop speed is ~ 1/2 C.

That all sounds good except for the XTAL, I think that may not be the right direction, here's why...

Way back in history I used to work for an outfit that built FM telemetry transmitters for rockets. A problem was that the rockets were really rough when the motors were running and that vibrated the crystals causing incidental FM which robbed us of useful deviation. So, the solution was to encase the crystal in a little cube of custom molded, very low durometer silicon rubber. Their leads were cut short and brought out along with a case ground using Litz wire. They were then largely isolated from shock and Vib.

Perhaps a similar approach would be of value for audio. Using lead tape seems to me more likely to lower the resonance rather than to provide isolation.

Good luck in your quest...
