Does this servo cope with heavy steering loads?

Yes, the torque rating supports heavy steering demands, though gear type and servo saver setup will affect longevity under extreme loads.

How noisy is the coreless motor at idle?

Coreless motors are generally quieter and smoother than brushed designs; you will notice less cogging and reduced idle noise during neutral steering.

Should I change my servo settings for off-road use?

For off-road use, soften endpoints slightly and lower rates to reduce abrupt movements that could unsettle the chassis on rough terrain.
