I emailed Austin (FRC971) who did all the real leg work, we just helped with production and resale. He should be able to be able to post more info.

I'm also really glad to see 971's mxp available I nearly considered designing my own after seeing theirs. What model of gyro are you using?

We are using the same model that Jared noted below!

They will not be sold via VEX, but for our Canadian customers we can ship via USPS if that is more affordable. I know it won't be as fast as direct ship from VEX Canada but it should be cheaper than FedEX.

You will have to wait to find out tomorrow

Sorry that's my fault,the tube comes with the tire as shown in the picture. Editing description now.

Also, is there any possibility of inch size single-flute router bits?

We will have both tire pictures up tomorrow and hubs in a couple of days. CAD will follow tomorrow. For the endmills we went with Metric because:

• The metric endmills are cheaper for our customers. I understand that most customers will need to buy a new collet, but it will really save them money over the Onsrud ones.
• The 4mm will allow you to create tap holes for #10-32 and router at a good feedrate. In the past we've used 1/8" endmills to create this hole, but have broken way too may endmills. Moving to 4mm has been fantastic.

But David, if you'd still like the english standard please email me sizes and QTY.

Those are all pinions for the smaller legal motors in FRC. They are .125, 4mm and 5mm press fit for those motors. None of the pinions are 1/2", you can download and check the models as well. We do have larger pulleys in 3mm GT profile in production, but I'm unsure if we'll get them in time for teams this season.

Side notes belt are now in stock, picture soon to follow.

Update,

The pneumatic wheels page has both variations of tires we are selling. Hubs are different for both products. CAD is up, the tread is dumbed down (Will be updated later).

GT2 Belts has pictures and in stock qty's.

We've been designing custom boards since the 2012 season. When the new roboRIO was coming out, we knew we were going to design a board to at least add the gyro. As part of the beta test, 971 also learned about the sensor brownout issues (and had observed them before in previous years). We designed the board in about a month in 2014 during the beta test, and then had one of our local sponsors assemble it during the 2015 season. After a season of use across 5 teams (and an Einstein win with one!), we made some modifications to address issues found. RC offered to help sell it, so here we are.

We used the GEDA tools to design the board under Linux. An older revision of the board design files are publicly available on 971's website.
