Rix did you upgrade your Fighter to 4080 as the sock is a 4065?
As a lord of the RIMs, have you or some one pysicaly tried these two motors? There must be some trade offs between the 2 and would love to hear more experiences out there.
I've tested them all, they're both the same motor, just different windings.
As you pretty much said if you're going to do alot of slow speed offroading and climbing the 65 is the way to go as it's more efficient down low. If you want a top speed over 60 then the 80 is the way to go. If you exercise some self constraint and aren't super concerned about efficiency (ie squeezing out maximum range) then the extra mid range acceleration that comes with a higher top speed is nice with the H4080 (assuming you have a high current limit)

TC4080? is this speculation or is there more known about this? I have heard the Crown TC series is moving away from straight pull spokes.
And as Alex has pointed out, MXUS 3000 should not be over looked.
As Rix has said the the new crown (TC) motors DO have the modified cases for a normal style paired spoking arrangement.
I tested the 45mm stator MXUS about 18 months ago. It was quite a slow wind which only did around 45km/hr on 72v so would have been a great high voltage offroader. I assume from the above mention of it they're now making it in a faster winding. I found it to be a bit underwhelming in performance but perhaps because of it's low top speed it spinted straight to it then had no where else to go. Quality wise the didnt seem quite as good as the crystalyte so I figured the H40 was the better way to go (and at the time offered better winding options). Does anyone know more about these new models ? Do they have a stamped stator or a cast one ? If they have a cast stator they'd be worth seriously considering, otherwise they fall between a H40 and TC40 in terms of performance.

Kepler or Hyena, do you guys know if the Fighters are actually 4080s or 4065s
As I've mentioned before crystalyte have a bit of a whacky naming convention.
The 40 relates to the stator width (ie 40mm) and the second number relates to the speed in a 26" wheel and a given voltage.
When crystalyte first started making the H series they were available in H3525 and H3540. These did either 25 or 40km/hr in a 26" wheel on 36v (ie a standard mountain bike sort of package) Then stealth started using them in the older fighters and specced them to run on 48v. Crystalyte then changed the naming code to suit running on 48v, and the fighter motors because known as H3548 (which were probably just 36v HS3540s run on 48v) Then when they announced the H40 motors I asked them to be specced to run on 72v and they came out with the H4065 and H4080 - meaning a 40mm stator that does 65 or 80km/hr on 72v in a 26" wheel.
The crowns used to be just TC80 or TC65 as they only had a 40mm variant so they dropped that part of the name. But they now have thinner models of the crown as well, hence the name is now TC4080 etc or TC35 for the thinner ones.
