Beryllium spheres - reminds me of The Shadow with Alec Baldwin. LOL.

Is your Wallmart battery anything like the Tamiya battery used in the Fostex FR-2LE? The dimensions seem about right for that, and they also seem to be popular for radio controlled cars. Was there a connector on the pigtail? Did you see any 7.2v batteries while you were there? Maybe we've found a new source for all our battery needs!

Do you have the stock number or catalog listing from Walmart? I didn't see anything like this when I searched their site.

Looks a lot like the Tamiya battery for the Fostex FR-2LE.

See here:
http://www.fostexinternational.com/d...FR2LE_OM_E.pdf
page 21.

Did it have a 2-pin Molex connector like the one shown on page 21?

Also, what are you using to charge it?

Pilot Weights

By the way, I just ordered more Pilot screw-on weights. I'm hoping this will make it even more stable. By adding weight to the stage, I can lengthen the pole and still keep the same camera height. That's the theory anyway. Also, a heavier sled should have better inertia with the arm.

I ordered 8 of the heavier middle weights (Tiffen part # 801-7920-05). Each middle weight is 4 oz, so 8 weights is 2 pounds. Total cost was around $50 ($6 to $7 each).

The smaller rounded end weights are 2 oz. The total weight will be 9.5 pounds (6 pounds camera & battery + 3.5 pounds screw-on weights), which is just under the limit for the Pilot.

I also pre-ordered the EFP Training DVD (Tiffen part# DVD-200504).

The picture and measurements from the description match the Steadicam Pilot AA battery holder exactly.

I'll post when they arrive ...

The battery holders arrived this morning. A perfect fit for the Pilot AA battery mount. Just insert the batteries, plug it in, and it works.

The backs of the holders didn't have the steadicam logo plastic cover, so some of the metal battery contacts were exposed. I solved this by covering the back with black gaffers tape and then trimming off the excess with a razor blade. Then I put a P-Touch label on top of that so that I can tell one pack from another.

It looks like the seller on ebay has 1 more of these left:

Hope this helps.

I took some pictures of the battery holders:

With this setup, I should be able to leave the AA chargers at home, or at least keep them packed away for backup.

Also, I found different brands of batteries to be a little different in weight. I had to re-trim the balance of the sled for the Panasonic batteries. I might end up getting another 8 Powerex batteries.

By the way, I'm keeping some regular Alkaline AA batteries on hand as backup just in case.

Has anyone tried 10 Alkaline AA batteries on the Pilot to see how long they will last? I thought I heard it was around 8 hours or something, but I don't remember where.

You might want to be sure the monitor can handle 15-16 volts, which is what you'd get with 10 fresh alkalines. The 10 battery idea is mainly for NiMH batteries, which are 1.2v. I heard something about 2 "dummy" batteries being used with 8 alkalines so the total is still 12 volts.

Yeah, I thought the same thing at first, but it turns out that most of the pro 12v batteries (including the ones Tiffen recommends) charge to around 15 volts anyways, so the monitor can handle it no problem. See here for details:

By the way, in case you didn't see the other thread, the NYC area Flyer/Pilot class is a go.
