Where might I be able to find a steel battery tray? I'm way light right now and that would be perfect.

I am working on making some steel and brass trays.
I will keep everyone posted as things progress. Here's a pic of the tray I have for my car and some pics I said I would post of my hubs. (no bearing slop at all)

I'll post specs and options once I begin the production run.

I will start by posting 3D CAD images as I finish them.
Please not that although the brass trays will be sweet, they will cost more than the steel ones due to raw material costs.

Ok here are the preliminary 3D images.

I will be making a spacer plate to add more weight for those using lighter Lipo packs with the bumps on the bottom. I will sell them as a set or seperate, just in case someone uses only larger packs without the bumps.
The tray will have cutouts for the bumps in order to get the pack as low in the chassis as possible.
Notice the recesses for strapping tape!

I have a SOLID 1 piece metal (heavy) battery tray...you know the person who originally create that. It is for foam chassis...but very good craftmanship.
Actually, it looks EXACTLY like what YoDog...may be YoDog did the prototype for "him" from last year September time...(P.S...I did not make that plate, I just owns it now)

Socko...when are you going up North and play toy cars with us? So I can have a good excuse to run foams (or may be the rubber 13.5)

I did not make the plate shown in the earlier picture but I do intend on making the one proposed in the 3D drawings.
It might have been made by the same guy that Solara mentioned. What did you guys pay for the steel ones, if I may ask? $70?
That's what I was told by the guy I bought my car from.

By the way, this plate is for the E4 rs and fs kits only.

I just got one from Bitty Design in Italy. Its light, but that will allow the weight to be balanced out better.

Wow timing is everything.

We have been getting jerked around by one machine shop for the last 6 months. We should have dropped them sooner but it always seemed like if we just hung in there it would get done quicker. That was not the case. So I am happy to announce that we are now ready to ship our new steel battery tray. We have tested MANY versions and materials and have come up with this design. It is machined from solid steel (brass caused other problems so we abandoned it) and it is plated with black zinc. It is CNC machined and is optimized for a tight fit so that the battery doesn't "hammer" from side to side in the middle of turns. We also designed it to be as heavy as possible. The rationale is that if the car is heavy, material can be removed from the front, back or sides via belt sander or step drill to fine tune the balance. Since this is such an important part of a great handling E4 we have priced it with little regard to profit. Street price will be $49.95. This is less than some machine shops quoted just for the labor. We made 200 for the first production run so there should be plenty avaialble. They will be on our web site later tonight.



We are also working on some other REALLY cool parts for the car to make the car even more competitive. More information will be released soon. I will tell you that a lot of titanium and 7075 aluminum is involved. The prototype parts are on my car now and all of our team cars will be runnning them at snowbird. Feel free to email us with any questions. They will ship Friday or Monday at the latest.

Geez Wolf, do you think you posted a big enough picture?

It's freeking my browser out!

Nice to see you are getting the trays done.
I think the ones I'm proposing will add a little more flavor though.
