Interesting..... which is better? carpet? asphalt?

I am in the process of putting an LRP Sphere 2007 ESC and Novak 13.5 motor (with sintered) into my RDX this week. The BL motor weighs about 30 grams more than my CO27s; so, I figure to do two things to get the car's side-to-side weight as balanced as possible: 1) change to offset motor mount; and, 2) go to a low-profile servo to eliminate weight.
Anyone have comments on their preferences between the KO low-profile servo (2343?) as opposed to the similar Futaba unit? I know about the price difference. Many thanks.

Hi Jeff,
That's what I am trying to avoid doing...or minimizing.
EA,
To the rescue with exactly what I needed...as usual. Wait...Aren't you driving an Xray?
Many thanks both of you.

I'm using the Orion Carbon LiPo, and struggling mightily with the car's balance. I've run out of room the put weights on the right side. I've got 8 gram Corally weights stacked double tall in all the slots behind the battery and single 8's under the layshaft. I've got a few 8's in front of the battery. I've got flat weights in the top groove in the battery under the strap. I've got weights on top of the battery strap. It's ugly as hell, and I'm still about 3 pounds light on the right side.

I heard someone say it's 1/2oz lighter, but I haven't tried to verify that for myself. It's definitely lighter though.

XRay has those things on the chassis that keep packs in place, which seem to work, but I can't think of something similar for the RDX. Right now I've got a couple of thick rubber o-rings glued to the chassis to keep the battery from sliding into the motor. Maybe I should tape. :-(

method to keep 4800lipo on chassis
I simply made a battery holder out of kydex. It goes between the battery strap and the chassis 75% up the battery. Holds the battery in rock solid.
I took a piece of kydex (bumper material) about 1/8" thick and cut it out with a band saw and dremel.
I can trace the brackets and post them also.
To balance out the car, I would do the following:
stick lead weight tape (the thick kind) under the battery in the battery slots. This will give you 6 rows to put weight into and should help to balance the car. This will also lower the center of gravity which putting the weights on top of the strap messes up.

As for the weights on the underside, do you have a problem with them hanging below the chassis or falling off?
The LiPo being so light actually gives you the opportunity to keep your weight much lower on the chassis than a traditional battery if you do it right.
