Okay Jerry, I took your advice and spent $135 bucks today for an
Odyssey 16 Amp-hr dry cell that weighs 15 pounds (the 680). I cut the
aluminum for a bracket on the gyroscope to mount it but I gotta get
Kevin to TIG weld it later today.

I ain't no genius, but my thoughts are that....
the Odyssey battery is all wrong for your application.

Now go ahead and make a fool of me. g

If he is using a battery which one would work better Bob?

How about a_40 lb_Odyssey, Jerry? g

The first concern is to successfully SIZE the battery
to this unique demanding application. A 16 amp-hour
Odyssey is going to empty out pretty quick unless one
is willing to start the blades rotating by hand. If one has
to do that, one may decide that the starter, battery, etc are
not worth all the time, effort, weight, complexity and cost.

OTOH......
just keep upsizing the battery until satisfactory performance
is achieved or the gyro is too heavy to fly. g

All this is going through my mind without a shred of
practical experience. So.... take it for what it's worth.
