In this video I looked at the "Frequency - Reactance Nomograph" and used it to check what Q factor to expect for a certain series or parallel tank circuit.
Picture with values of coil from resonance kit:

The experiments where done without impedance matching, it's clear to me we must use that also. This video is to show results without the matching.
Warning:
Experiment at your own risk, the parallel circuit will blow up gate driver even when directly switched on in resonance. You must foresee current limiting part when using parallel LC
