IMO I’ve seen what’s essentially a 775 pro available from east asia OEMs. I believe WCPs design work was just choosing the correct spec (ball bearings, CRFP fan, Windings) and doing the testing for FRC use.
I wish it was that easy… 
I’m assuming the Armabot RS7 encoders will work on the RedLine motors, since they’re the same as the 775Pro’s, & it looks like they have them in stock now.
Not saying it was easy but I’ve seen the specs available. I’d love to know more about the process.
I’m betting against that. There have been puhlenty of times in the past when new wheels have come out that ended up being useless for the coming game. I’m pretty sure that the Vex and AndyMark folks are telling the truth when they say that they have limited information about the games (I’m the trusting type). I still think that the bits and pieces of data we have currently indicate a tiered field.
As some have expressed above, I’m interested in hearing the differences between the Red Line 775 and the 775Pro, as well as the Sport Gearbox vs a VersaPlanetary. Also the AM Mag encoder vs the CTR Mag Encoder.
I’m digging the voltage flags for batteries! Way to go 1720!
I’ve been one of the biggest vocal fans of 775pro drivetrains, especially having used one in a season, but I think at least for this season it would be worth putting some kind of note about paying attention to voltage/current levels when using the new EVO gearbox with the 775 Red Line motors. I only say this because to a lot of people, they are going to see are new motor that seems to be primarily for drive trains based on the items being offered. Not all teams will know to really dig into the motor specs and understand the limitations of using a 775 in a drive, they’ll just trust that they can slap everything on like cims in a regular gearbox and run.
Otherwise, I don’t see an issue with offering a drive gearbox for 775pros. AM has always been great about supplying to support to the community regarding their products, so I wouldn’t expect anything different here.
They’re only cheaper if you’re absolutely sure about what ratio you need, as soon as you start changing ratios it gets far more expensive, since with VersaPlanetaries you can change out the $15 reduction but with these (at least as far as I can tell) you have to replace the entire gearbox. Granted, this isn’t necessarily a bad thing, just something teams need to be aware of when planning.
On a separate note, the DeCIMate gearbox is very interesting to me (it actually reminds me a bit of a similar gearbox I designed a few months back), at the weight of a MiniCIM it has more power with both motors installed than a full CIM. Might be an interesting option for not only mechanisms, but potentially even a convenient drop-in replacement for a MiniCIM in a 2CIM+1MiniCIM drive gearbox (if, for whatever reason, you needed that much power in a drive system).
EDIT:
Anyone else having trouble opening the STEP file for the DeCIMate in Inventor? It keeps locking up the importer for me. =/
Welp, a little on the nose?
Any plans for an EVO Slim gearbox for CIM drivetrains? I like the EVO Slim a lot but I am not comfortable with 775 drivetrains (yet).
I can confirm that this is true. We opted for this design to increase reliability and decrease cost. We may sell the individual internal components in the future, but have no immediate plans to do so. If you dive into the layout files you can see that selling individual parts has the potential to be a bit complicated as there is more than one “version” of each each ratio, so you can’t simply say “here are the gears you need for a 4:1 stage” It depends on what goes on either side of that stage.
I’m going to call it, I don’t think the manufacturers of the 775 pro and the Redline are the same.
We know from AMs motor curve sheet that the Redline is a CCL Motors DF30 motor with a different winding specified. CCL is also known as CIM

If you look closely the 775 Pro motor has a slightly different brush holder design and according to the drawings is slightly longer. I believe their motor is made by Kinmore motors.
Now this is all speculation and the specs could be identical but I’d like to know if they really are identical.
Darn, CCL catalog must be out of date. I thought Kinmore was the only one with that brush style.
The 775pro is definitely a CCL motor… The one on my desk has a CCL marking on the rear…
As stated previously in this thread, the 775pro (and apparently the Redline) is not an off-the-shelf motor available from the CCL catalog, but a custom configuration VexPro ordered specifically for FRC from CCL.
So what would be a good reason to use the new PG27 gearboxes over a 57 Sport and Redline?
Comparing the PG27 to the 100:1 57 Sport (same output speed), the Sport+Redline is about $20 more and 0.1lbs heavier, but gives ~280% more torque. If you don’t need the extra power, you can limit the Redline to ~70% voltage and use a 64:1 for the same speed, and the option for more power if you find later you need it.
Darn it. Before the 775 pro came out I’d been looking at the more powerful 775s available from manufacturers like CCL and wondering why no one offered them for FRC.
When VEX released the 775 pro I figured they were just a normal part # with VEX branding. We** joked** about trying to import some with our team name on them for giggles to see if the inspector would allow it if the #s matched (like you could with a Banebots motor or a CIM).
Because of the slight differences (and before we had one in our hand) and the fact that AM didn’t offer a mini-CIM we figured VEX wasn’t using CCL but someone else like Kinmore who offer analogous products because both the Mini CIM and 775 Pro have custom part#s compared to even VEX’s CIM.
After hearing about the Redline I still had doubts CCL was the OEM as I figured there’d be some sort of exclusivity in place but 
A few reasons actually,
- With the PG you get a “free” encoder pre installed
- The PG series now comes in 3/8 hex out of the box if you want it.
- Per the 2017 rules you could run 2 PG gearmotors off one speed controller saving you PDP slots and $$ in speed controllers.
The refreshed PG gearbox line was developed before, and independently from, the Sport line. We really just wanted to get away from the 10mm key shafts…
You must spread some Reputation around before giving it to Michael Hill again.
I believe we have similar tastes in YouTube channels seeing as the last rep you gave me was hydraulic press channel related.
