I am, however, still curious about the trickle charger. Is it
advantageous to have this plugged in between flights if you fly at least
once/week or is it actually detrimental to the life of the battery?

Depends on the type of battery. Recombinant, Jim has said hates that. Lead
acid would rather be full than sit around discharged. Gel cells (lead) hate
to sit around fully or partially discharged.

The key to any trickle charger is the cut off voltage, too. If one is set
too high, then it is always bad. A correct cut off, and IMHO, you can't
hurt lead acid.

Real world, is probably flying it once a week or even twice will not require
anything, if your charging system is working correctly.
