VEXpro 2015 Product line launch

[Jared]

The output shafts and shifting dogs for the WCP DS gearbox seem to be dead links right now. Do you still plan to sell the output shafts and shifting dogs separately?

Also, can the shorter steel shaft that fits inside the gearbox output shaft be purchased separately too?

What wire gauge and twist count is used for the CAN wires on the Talon SRX?

Used, or recommended by the developer?

While beta testing, our team used 20 AWG green and yellow purchased on separate spools (e.g., McMaster 8054T14) and twisted pairs ourselves with a vise and drill, to about 20 twists per foot. So far no issues. We twisted to get good handling/routing, not to solve an EMI problem.

The wire spec is 20AWG per the drawing on the site, the twist spec we use is 1 revolution per 14-21mm.

Thanks for the information!

If the recommended wire and wire that is used are different, I would like to know both. I am assuming that that VEX Pro / CTRE would use the wire what they recommend; but, I can understand why they may be different.

The Shifter rod has been added to the 217-3628 Shifter dog Kit.

And yes the shifter output shaft will still be available by itself.

Where to you find rivet nuts that go in a 1/4" hole all the ones I've ever found use the annoying 19/64" bit. Because it is a less than common size we keep it in the kit with the rivet nuts so it is there when we need it.

Our 2007 Aim high robot vibrated 1/4-20 nylon lock nuts off... multiple times...

Were you reusing the Nylocks? They are a one time use item, though you can often get by with using them a couple of times.

We've still got one more thing for 2015 - the Ball Shifter Shaft v2 is now available.

[ToddF]

Now, if you would just get 2 CIM ball shifters in stock...

The 3 stage 2 CIM ballshifters are back in stock (217-2615) the 2 stage ones will be back in early next week, several factors out of my control have been delaying shifters in general, wrapping them up.
