Hmmm, something like this?

That's a 1512, a 1717, and a 2025 motor side-by-side.

And the OD on the end-bell for the 2025:

Good grief! That 2025 motor would make a good e-bike motor and would probably carry my fat butt around, let alone an r/c!

Linc's right; I was thinking of something a bit smaller. Basically a line of motors in between the CM36 series and the 15xx series. Medusa had a solid line of motors in that segment; the 36-50's were stronger than the CM36 motors (sorry to say that here, but it's true), so were a better choice for heavier 10th scales (eg: Slash) or smaller 4WD vehicles (eg: CRT.5). I tried a CM36 4600 motor on 2s and 3s in my CRT.5 and couldn't gear it low enough to keep the motor and ESC cool, whereas the 36-50-3300 stays cool and has noticeably more torque, even geared a little aggressively. Medusa's 36-60mm motors were good for the really light-weight buggies or overpowered 10th scales (or allowed higher gearing for 10th scale speed freaks). In short, that would mean 1506/1509 or 1409 sizes if using Neu ratings.

Taxes are taxes, but that's not what I meant lol. In Europe, you're not allowed to make our wonderful ESCs over 60V lol.

What do you mean exactly? Is it just for "toys" manufacturers? I'm in Switzerland (not in the European Union) and planning a car to operate on up to 30s LiPo. I've heard that Germany has very strict laws for high voltage.

CE won't allow sales with exposed voltages above 50VDC. So no CE approval for anything designed to work with exposed voltages above the "magic" 50VDC.

Also coming. I didn't post a picture of the 1307 and 1309 motors, both of which are in prototyping now.

I been asking steve neu to make a 13 series for a bit now, he did do a 14 series, but its just a smaller diameter (outside) can. What will be the KV's (hopefully a 3500)?

I like!

Any video of that 5b

Wow, looks like a nice lineup. Cant believe I didn't see this until page 3. Things move quick around here. Now I just need that production Mamba pro.

Patrick,

What's that polished silver motor doing behind the big one?

It's another motor I can't talk about. :P

Hmm, good guess by me! Do you plan to replace the cm35 motors with the 13 series? Or will you just sell them separately?

I think the 13 series would be a better option, the finned can (figured CC would stick with finned cans for the car motors) would be about the same diameter as a regular 540 can (36mm OD). Plus the smaller diameter rotor will spin up faster, and the 4 pole design will have plenty of torque.

But it is another motor that exists!

That's exactly why i asked specifically for a smaller motor, better torque band for 1/10 cars. The 14 series is only a 15 series with a slimmer can

Some sensored 4 pole motors would be very cool. The MMP with a low kv motor could also be packaged as a crawler/low speed setup. Sensored outrunner motors or a hybrid style (think align but better made) motor would be great for anything that needs good low speed control (robotics applications also). As versatile as the MMP is a good selection of motor designs/styles would be very nice! And CC pricing is great too!

The 14 series always seemed like a bad idea, too close to the 15 series, not much benefit.
