Seems rather small and the kv is quite high- normally something larger than a regular inrunner would be used with a much lower kv, with the front & rear diffs being directly driven by the output shaft sticking through both ends of the motor. Linc & Sike are the outrunner gurus though, woudl be worth doign some digging and research into outrunner setups around here..
I'm a little ambivalent right now. Flip-flopping between 1900kv and 1700kv, and then I saw some guy over on oople who ran a 1600 outtrunner in his 8ight. It's mostly for the weight savings, that Castle Neu 1717 1Y is a heavy beast.
I have it down to 85% EPA, making it equivalent to a 1900kv motor. It barely breaks 60c after 20 minutes.
Ok I misunderstood then. Anyways, if you want a 1600kv + outrunner I'd suggest getting a more powerful one. Gotta keep in mind that there is no gear ratio to help it.
I'm not an outrunner expert either, but from what I've read an outrunner can generally be a bit smaller than an inrunner and still have the same or more torque. The motor you linked will probably well in an 8ight. Here's some good reading to help you decide yourself. http://www.rc-monster.com/forum/showthread.php?t=27799
Yeah he put it in an Erevo, but the principle is the same. His tests with different gearing and battery voltages or worth the read though. Let us know how it works out.
The only experience I have with an outrunner in a car/truck is in my SCX10. It works great, but you can't really compare that to a 1/8 e-buggy.
If you decide to try that motor remember to grind a flat spot onto the shaft for the pinion set screw. Put the motor in a plastic bag and poke the shaft through
Along those same lines keep in mind is that the motor if relatively open to the elements, if you run in dirty/dusty areas make sure to keep an eye on that. Should be able to blow dust out with a compressor, but a pebble lodged between the magnets and windings could spell trouble.
