Hmm, i have to disagree. :) Well maybe its because of the fan + extra heatsink, but the motor was 50-60C after driving. And I was driving inside, so the environment temperature was 20C+.

My pinion is 13t and spur 45t or 46t, so its not that heavy i think. I put low timing on ESC and low start power to keep the temps as they are now.

When I ran the motor outside, around 0C, the motor didnt go much over 20C :)

But yeah, compared to more expensive motors, these get much hotter I guess.


EDIT: The quality of these china motors also vary alot. Last 2800kv XL short circuited because some axle balancing epoxy kind of substance came off of the axle/magnet and went between magnet and coil. So some motors might also get hotter than others.

Hey guys I have gotten alot of stuff done over the past week.
I realized how heavy the rear of my truck was, and wanted to lighten it up in preparation for racing... so I started to take parts off and weigh them.. come to find out that the motor mount that came with the truck was heavy as hell! ~245g. Its made out of some mystery metal, its really heavy, really stiff and not magnetic.


So last night i got to work on a peice of 2x2 aluminum. Its mounted to the chassis with 2 countersunk m4 screws. about an hour later with the aid of a drill press and a dremel this is what I came up with. 44g! dropped 200g on the mount alone!



Secondly I got a spektrum sr3000 from a friend, and bough a module for my M8. got the module installed and modded the case so the antenna fit's in the stock location- it looks pretty trick








here are some other random pics.



Also Got my lipo back from linc, great job
