I'm gonna use this in my new Ultra Sport. No more charging batteries and it will last for about a year before it needs replacing. It fits right under the canopy, so I can just remove the canopy and replace it.

And the canopy will be painted black, so you won't see it!

Whaddya think?

Looks good to me. I am beating that the plane will balance nose heavy !! Dave

That's the beauty of it. It's almost right over the CG.

Happy April 1st!

Minnflyer, any idea where you guys will be approx. noon on Sat.

Gene, we will be at the foot of the big staircase near the main entrance from 11:45 till noon Fri and Sat.

Well, Lord willing and the creek don't rise we will be there. See you guys Sat.

Should fly inverted just fine, 'till the battery falls out.

Gotya beat MinnflyerI put a 6v car battery in my big Bingo to get it to balance.

It'll be strapped down with Zip Ties

I'd run two of those so you have some built in redundency. One in the nose and one in the tail should get it to balance just fine...

Better yet, how about a 12V deep-cycle marine battery with some sort of complicated regualtor system?

Actually, I'm thinking about one of these. 80 Volts, 750,000mAh should fly the plane for a few years before racharging. It does weigh 74,816 ounces though so the plane might need to land a little hot. No inverted flight either or all the electrolyte will run out.

Hey ChuckW

My kind of battery.

i wonder if one of [link=http://www.rsc.org/images/Fuel%20Cell-Ballard_tcm18-115162.jpg]these[/link] will work for 5 years

If you mount it nose down the springs could be used instead of foam. This might negate the little weight penalty from the bigger battery.

david

Got a voltwatch for that? [8D]

cool idea Minn....you guys are funny

What will you use for a field charger?

He is just going ot have consumers power put a sub-station at the field.

well if you can put that big of a batt in a airplane and get it to balance.....then i can put a 91 four stroke in a 40 sized plane

Chuck, That is a good idea for a 1/2 scale electric conversion. 750 amps should fly it for about an hour or so between charges.
