Could I use a car 12 volt jump cable starter, the kind that is a heavy duty

I did so?

Um, you didn't purchase the "jump cable" option with the glider?
You've maybe seen me use it in "A Fine Week of Soaring"...

Sure, you can jump-start without the factory kit, but BE CAREFUL!
As long as its less than 14v or so.
I'm not sure how you'll safely connect the jumper cables though.

And, make a point of replacing that battery every yeary or two,
as it seems to degrade rapidly when called upon to deliver
starting current. The batteries are very inexpensive and it
saves a lot of aggravation.

Hope that helps!

PS: I'm ordering the jump-start kit with the new toy ;-)
