There are quite some bytes allocated by telemetry module for setting the logging period for registered UAVOs.
telemetry.c comment makes a note about logging period stuff:
If coptercontrol does not use logging module (as it seems to be the case), then there is no point in doing the logging period magic. Voiding setLoggingPeriod() function saves whopping 1056 bytes of RAM.
Are there any downsides to doing this?
