Refering to the battery going directly
to the starter, most all starters with built in solinoids are so
wired. I remember having a starter to hang on occasion and drain the
battery or ruin the starter. Is it practicle to use a relay in
conjunction with the starter/solenoid set
up?

Wendell, I would say that is still a
standard for aircraft - for some on the reasons already mentioned.
With a relay(Contactor) you can break the circuit to the starter should it
stick or short. I also have a LED above my starter switch that is on
so long as there is juice to the starter - that way you can tell if the
starter is still engaged after the engine start - happens occasionally and
ruins starts and sometimes the gear teeth on the starter
ring.
However, there are folks who are now
doing away with the contactor feeling it is heavy and there is low risk of a
hang-up happening.
