The dual speeds do not have any encoder mounts. What we prefer in a WCD config is to put the encoder on the wheel shaft. Every VersaShaft for the WCD comes with a 1/4 hole that allows encoder mounting.

I know manuals aren't released ATM. We are trying to have them done this weekend so teams have more information/how tos available to them.

Let me know if you questions.

Thanks so much for your quick answers. It happens that I just did a design with the single speed speed gearbox. So that works just fine.

We got started on the manufacturing of the WCP items a little later than we wanted. Both WCP and VEX are pretty particular about design details so we released the drawings to production later than we wanted. The dates on the VEXpro website for the WCP items are still our expected ship dates. Please note that this is an initial inventory problem only. Once the items arrive, WCP, The Robot Space, and VEX will have plenty of inventory for the entire 2014 season.



We are working on the application drawings for this and should have them by the weekend.

Thanks for the prompt reply.

Paul, JVN, RC, do you have masses for the 3 CIM Ball Shifter WCD version?

3.05 lbs

*For most products on the WCP page, if you configure the product it will update the weight for you

Also, how do you use CIM style motors with VersaPlanetaries? I saw that you used them this way in Build Blitz, and that they could be essentially "officially unofficially" used like this in last year's version. Is there any special trick to doing it this year? How do the CIMs mount, etc?

I had the same question. Check this out from last year.

I remember hearing something about products beings shipped from WCP will have 2 day shipping to any California team. What do you guys think would be the standard time to ship from WCP to Portland? Is Portland close enough for that, or would we have to pay for 2 day shipping to get it in two days.

We know that teams may wish to use it for this season, so we're working quickly to get it posted. Productization includes things like final design reviews, pricing, making a webpage, etc, all of which just take time.

Team JVN used a method similar to the Spectrum post linked above, and I assume Team Copioli did the same. The only difference is that this year's VersaPlanetaries include a few minor adjustments. One is that there are new motor mounting plates - for the CIM-style motor application, you can just ignore mounting plates and mount the input stage directly to the CIM. The other is that the input stage no longer has a bearing inside; the CIM shaft fits directly into where the collar would normally go. It pretty much "just works."

The necessary disclaimer is that VEX doesn't officially recommend or support this. Team JVN used a Mini CIM (stall torque ~1 ft-lb) through a 9:1 single stage, which is as high as they were comfortable going. The numbers technically work, but keep in mind that reversing or other shock loads can lead to torque transfer much higher than that 1 ft-lb at stall. It worked in this case because it's just an intake roller (low impact), not a rotating arm or something like that.

So, you're saying that Team JVN was "comfortable" going up to 9:1 Versaplanetary, but what is the general of "rule of thumb" stall torque maximum for the versaboxes?

We tried finding that value a little while ago, but couldn't really find it in the documentation.

Most if not all California orders ship in one day via FedEx ground. Surrounding areas such as Washington, Oregon, Nevada, etc.. ship in 2 days via FedEx ground. You can see the FedEx map here. We are just receiving our initial shipment of parts from VEXpro tomorrow and orders will start to be packaged and shipped the same day. We apologize for the delay of getting these orders out to customers as we know these orders are extremely time sensitive.

Thats great. The only thing we have ordered so far is the SS gearboxes, but will most likely have a very large order sometime next week. If its 2 day ground shipping, we will try and get it in either monday night or sometime tuesday, so hopefully it would be here for saturday assembly.

Is it possible to get the 2 stage ball shifter with a 4" long output shaft? The CAD model of the "long output shaft" 2-stage shows a 1.59" long shaft.

Martin,

The "long output shaft" is intended for sprocket/pulley drives to a final ratio, as such the max length is 1.59".

If you want to extend this shaft you may look at using one of the colson live hubs as a hex extension to another piece of axle (rather deep hex bore).

Or if you're up to it you can press out the axle and insert your own (heat will be required), this may be difficult but is doable. If you take that route please pay attention to internal features you must replicate.

I'm having issues with the CAD model for the Versa Planetary gearbox. When importing, the two halves of the case aren't lined up right (see picture), and I can't get them to line up right while having the hole for the bearing aligned.

I'm a little curious what's going on with your model, every model I have this is not an issue, have you tried re-mating it? I'll reupload the STEP file just to be sure.
