I might just give it a shot. Heck, for $39, i'm not losing much if it doesn't work very well.

If it has anywhere near the performance of the align motor you will be happy. The spool up was slightly slower than an inrunner, but so much more torque. Very smooth power delivery as well. And it did not get hot at all. Hope the UH hybrids are as good as the align.

I think like most outrunners its just a matter of losening a set screw that holds the shaft in place and replacing it with a 5mm shaft that isnt turned down on the pinion end. Should be easy to do if you can find a 5mm piece of rod and cut it to length. I could be wrong on that, but I think that is the case on most Outrunners.

Hey Jhautz,

You just described exactly what I did to the very motor I got from you. LOL

how about this?
http://cgi.ebay.com/ws/eBayISAPI.dll...MEWA:IT&ih=020

Does the shaft come out in all out runners? This cheep ebay one also looks like it has a bushing for the shaft on the mount side, is this normal?

I have found a few that the shaft doesn't come out of, such as certain models of the Century Brand Outrunners. It's a press fit PITA.

That's not a bushing that you're seeing, it's a spacer. This motor does have bearings. I've never found an outrunner that didn't have bearings.

They chose to go with a spacer and a snap ring instead of a lock ring collar.

The ebay emax motor is 180gm. Pay attention to the weight. 225gm or higher for an Emaxx.

not to hijack this tread but if the numbers are the same why is the weight not the same or close?

I didnt see anything in the revision history on the CC site.... What do you know? Is the fabled MM fix finally about to be released?

johnrobholmes 01.22.2008 01:52 AM
They got the C link done, the webmaster should upload it onto the site tomorrow.

Because sometimes a manufacturer will stretch the truth a bit. I have found the easiest way to rate an outrunner is with weight. Same for batteries. If the motor is too small, it will have to work a lot harder. If the motor is too small, it will also have trouble dissipating heat. I have that emax motor you linked to. It is about 6.5 ounces and not really all that powerful (for a revo). The air gap and stator laminations are huge too, so it isn't very efficient.

It would work, but you will either have so-so performance or the motor will burn up in short order.
