Why is this nitro motor terminology "Big Block" being used to describe an electric motor? It doesn't shed any light onto its actual size or rpm it just looks good in big print on the box.
So if the XO-1 uses the "Big Block" the 1/10 ERBL uses the "Small Block". Will that be printed on future ERBL boxes?

when you see the motor size you will understand its huge it makes a mmm motor look small
MINE ARE FASTER THAN GPS!!!
Lulz. I don't know the guy but I think BL has a lot of brushless experience.
Anyone know the kv for the new 17-17?
1650kv is what the site says
ERBE Summit E-Slayer
Ducati777 I think he just read the thread title.
Stop busting my canards!
There's no way Traxxas is writing "small block" on anything they sell.
Does "almost a big block" work? lol
Simply the best. The beautiful Traxxas SRT and TCP

No more MMM, now its MAMNQM
this motor is the Castle 1717 motor that did not sell well from Castle
I know because I bought 3 when they cleared them out
monster power from those motors
more like .50-.60 size nitro motors but full on power all through the rpm range!

Yeah, the cc1717 is a bad boy. It is kinda too big for 1/8 yet too small for 1/5 scale.
A cc1520 and a XL2 on 8s could smoke the RTR X0-iPhone noobs.
I did read that CC reworked the "Big Block"(Black 1717) to make it even better than the 2+year old Green 1717.

Are we sure this is a re-tuned 1717? (Can Size 50MM OD x 85MM L)

This is from Patrick regarding the Traxxas 1717
"We developed a whole new stator and rotor design for this car -- it uses a shorter and lighter rotor for faster spin-up, and is up to 4% more efficient than the original 1717.
The stator design was optimized for higher maximum currents, and higher saturation currents -- so the efficiency doesn't "brick wall" at extreme currents".
I have the original 1717 and like all green motors, it's build for lowend torque vs high rpm for the IO-1.

CC 2650 vs. 1717 That's the old 1717 but the new one will be the same size.
My lord that thing is huge!!!!!
I put it in a 1/8th scale truck that weighed in around 16 pounds fully loaded (tires, batteries, etc) and it tossed that truck around like a rag doll on 4s geared for ~45 MPH. On 6s the performance was just hilarious. I can't believe they tweaked and tuned that motor and stuck it in a road car, that car is going to be mental!
My input on the original question is that the term "Big Block" doesn't necessarily come from the nitro side of the RC world, but from the American cars of the 50's and 60's with the horsepower wars......big block, small block. I see it being used as a reference to a big, high horsepower, bad-boy motor more so than the nitro RC reference.

They will fit the E-Revo but it'll take some work. My brother fit one in his Summit but had to mod something to make it fit (rear shock mount, I think) and because of the diameter it's interesting to find gearing that fits but you can make it work. Wicked motor on 4s in a Summit or E-Revo!
ok thanks !

I had a question about the electronic cubic inches but then i saw the pic of the 17-17 motor next to the E-Maxx motor and then how it weighs a 4th of a lb so that really cleared things up a bit
Far left is the CC-flavor of the ERBE/E-Maxx BL motor, center is the old CC 1717, and right is their 2028 motor. That's a lot of awesome for one pic
