I responded directly to Tom Hall, but there seems to be enough interest
in this to make one comment to all: Don't skimp on battery capacity or
put them in a difficult location. Starting a turbine is not like
starting a piston. You've got to have full voltage and capacity or you
risk serious damage inside the engine. You need to be able to manage the
batteries much more than with a piston, and, I suspect, replace them
more often. If you leave the plane out on a ramp somewhere for the
weekend and the batteries are weak, you may be stuck. You may also be
tempted to push a weak battery start, which is risky. You should
consider a convenient plug for a Battery Minder and/or a solar panel.
Definitely provide a handy cart connection in the nose well (or
somewhere).
