I think they're actually the same kv though.Serum said something about some companies measuring kv by using the motor as a dynamo and measuring the rpms needed to produce 1 volt,wheras the wanderers may be measured under load.It's not a big difference anyway even if the method is the same,a low kv gives you less current draw and better runtimes(i think).

as well as the capability to gear a little higher, correct?

Yep,although i think they're the same kv in this case.

I'm no expert but from what i've learned in my short time at rc monster is,if you want big power and speed,run as many volts as you can(space/weight/and money permiting),to keep the amp draw down to a level your batts can handle(batts are the limiting factor),run a low kv (also reduces amp draw) and gear up to get the speed.You get more power and better run times this way.
If any of this is wrong i hope to be corrected (i prefer to learn than not ask for fear of looking dumb) but it seems like a sensible philosophy to me.

i believe you are correct. less amps drawn means the easier on the battery thus longer runtimes.

Man, I missed a lot of stuff in this post-it is moving fast!
Yes, I can and will get the blue wanderer motors, including the 7xl and many other winds. The difference between these and the eigaos I currently carry is the bearings(and the color!). The Feigaos have a low quality bearing(not that it wears out, it is simply a low cost bearing), while the wanderer has a better bearing. The difference in Kv is simply that Feigao states the value without a load, while BK states the value under a load. The motor are the same, so the kv value is the same.
The 7xl will out perform the xl3100, squee, simply because it is bigger and can more easily push the heavy maxx around. It can and will achieve the same or greater speed with the approprite gearing.
For the money, the Feigao/wanderer motors are tough to beat. The segmented rotors(upcoming) will be the icing on the cake, as they will run cooler in our car/truck applications(better efficiency at partial throttle). The current Feigao/lehner basic motors don't have the segmented magnet and therefore run a bit hot compared to the high end Lehner motors(19 series, for example). The 7xl is big and strong, and can take a lot of punishment compared to the smaller motors(without the segmeneted magnets), simply because the can dissipate more heat and have the torque to move the heavy trucks without working up a sweat like the smaller motors do.

I had one problem gustav with the schulze. One of the plugs slide out a little bit and burnt the plug off the esc. I soldered it back and kept on getting it. @squee I don't you will be disappointed in the motor. If I thought you would I wouldn't recommended it. Keep us up to date. @ When you going to test run the beast? I like to hear your opinion as well. Thanks mike. You just know how to word things.

@ gustav;

You understood great!.
