You might be able to find them on ADS-B Exchange, either live or in the historical data sets. They are somewhat famous for only using citizen-sourced ADS-B data and refusing all requests to delist or hide data (allegedly anyway).
It looks like their tail number is N542B but I'm not sure how to translate that to the ICAO hex codes that they use to archive their data nor exactly what date and location the flight took place. Some more sleuthing would be required.
