It looks like they're being called VersaBlocks. You can see a pic of them by mousing over them on the VP website or on the WCP website.

EDIT: Oops, got beaten to it.

Does anyone know if the 4 "center" wheels will have a 1/8" inch drop in a 8 wheel drive configuration??

Yes, each Versa-Block has a 1/16" offset built into it, which is consistent with the notch on the top of the block. By orienting the blocks, you can achieve a 1/8" drop in a 6wd, 8wd, or 10wd.

In a typical 8wd, you would position the 4 outer wheels with the notch down, and 4 inner wheels with the notch raised.

Thank you for clearing that up.
Are there pre-drilled holes in the outer walls for the different drive train configurations like 6 wheel, 8 wheel, etc?

Are the versa planetary base models 1:1 ratios??

No, the VersaFrame 2"x1" tubing does not have pre-drilled holes in the sides, there were simply too many possible drivetrain configurations to account for all of them with one pre-drilled tube.

The assembly instructions, coming soon, will detail the specifics of creating the holes in the tube for wheels. The general idea though, is that the hole can be very rough, all it needs to do is provide clearance for the shaft.

At WCP we used a 1.25" hole-saw to make all of the holes, using a drill-press.

So all the stress is being put on those blocks which are attached to the 1x2 correct?

Correct, the bearings are held entirely in the Versa-Block, so the wheel load is distributed evenly all along the top and bottom of the tube where it is clamped. The Versa-Block is by design, extremely robust, and the bearings are held .25" out from the tube, putting even less stress on the shaft/bearings then if the bearings were held inside the tube.

Yes. All of the base models have the input housing + output housing & shaft + motor mounting kit (with new clamping screw and plastic motor plates). This is what many teams used last year as their 1:1 gearboxes for shooters.

S_forbes,

The planetary gears have had the profile shift since the beginning. The gears from this year and last year are completely interchangeable. On the 10:1 gearbox, if there was no profile shift, then the rated load would be significantly reduced. The small pinion on the 10:1 gear stage has the most profile shift of any of our gears.

Sweet! Idk if its just me but in the picture on the WCP website, the 3 cim shifter has a internal shaft but the 2 cim shifter is shown with the external shaft. How will this work with the alignment of the sprokets??

[Thad House]

Any reason why the 18 tooth gears are $9,999?

Everything looks awesome here. The only thing is that the WCP gearboxes are not going to ship until the 15th. Is there a specific part that is causing them to be delayed that late?

What's actually going on is there are two different types to each WCP transmission. Standard, which the 2 CIM Shifter is shown as, is shorter and doesn't have sprockets or a bearing. Then there is the WCD, which is longer, and includes space for two sprockets and the bearing block. The overall shaft length for both is the same.

The image for the 2 CIM Shifter is currently a Standard, and the 3 CIM shows the WCD+PTO model, but both transmissions are available in either configuration. We are working on getting images of all different configurations up on our website.

Hopefully this is what you were refering too?

Yes, thank you for clearing this up.

Alec, if I ordered the WCP 3 CIM DOG Shifter, would it still have the plates of the PTO transmission, or would it be the plates of the 3 CIM SS just with a shifting shaft in there as well?

The plates for the WCP PTO transmission are the same plates as the WCP 3 CIM shifters. When you purchase a WCP 3 CIM Shifter, you get the plates necessary to do a PTO. Please note that only the WCD version of the 3 CIM shifter supports the PTO option.
