What possible use could you have for a 6CIM, 2-speed gearbox? Talk about overkill...

Exactly. Overkill

They had the pneumatic shifting set up at the table and it worked well. Hopefully, we can use it in the future.

What kind of pneumatic shifter was the set up. Was it the pneumatic that comes with the super shifter now or the pancake pneumatic like on the vexpro shifters.

Dunno. Personally, I want a robot that can hit 30FPS, but that may be a little much for 2 speeds.

Perhaps I can persuade my team to sell enough lightbulbs or find a sponsor to support the purchase of a couple of these for testing. If that happens, I will study the prospect more closely. I was given to believe that the same ratios applied and that the major difference was the more linear shifting process. It was not a pancake shifter (like I saw on 254's gearbox with PTO). Here is a picture of the demo at the booth.

I'm liking the simplicity of the box. Can't wait to see specifics and price!

Awesome thanks for the picture. I have wanted to see what this thing would look like since i heard about it. If it is anything like the super shifter with a centralize shaft; It would work great on my team drivetrain setup. Might even work better then the one i design for this yrs. drivetrain.

Just judging by the picture it doesn't seem all that different from the super shifter. Does anyone happen to know if and what the differences are from the super shifter aside from weight (apparently)?

I visited the AM booth at CMP, to see this and other new products. The new shifter is about half an inch taller than the original SS, is left-right symmetrical, and allows for use of 17 tooth CIM pinions as an alternative to the 12 tooth pinions used on the original SS. The demo rig pictured in Bill_B's post illustrated very smooth shifting, and is fun to play with.

I still want a RAW box.

For those of you who didn't know, AM released some more details on the "Sonic Shifter".

As I am design a new practice drietrain, I am wondering if it would be possible to change the ratios so that the high ratio is around 4-4.5:1. I can't find details of 17 tooth CIM pinions used with it, or how that would change the ratio (what gear do they drive?).
Because we are using 4" (custom) wheels (in a WCD configuration) and want to directly drive one of them, sprockets aren't going to help. Is there another source for 20dp 14.5pa gears that I don't know about?

Anyway, some CAD would help

4 Lbs, even with the cylinder? I know that it's made of aluminum, and should be a bit higher performance than a Vex Pro Shifter, but that kind of weight is hard to swallow.

Those massive alum top and bottom pieces only seem to serve as a spacer? Can't they just be replaced with some standoffs?

What I was thinking... also, are those the 20DP steel gears they are using?

AM seems to use the steel gears in there stock boxes....

WCP alum gears should be a direct drop in replacement and save a nice amount of weight, they also don't need to be heavily greased.

I'm not sure it's that massive. If you look closely it's not just a flat piece, the center appears to be thin, so really it is just stand offs.
