information on kb45 motors?

[lincpimp]

2 pole motor, internals are identical design to a hacker/feigao... The rotor is larger in diamter, and these motors are very powerful. I have only run the L cans so far, and they performed as well as an XL feigao with more torque and less heat. Not as efficient as a neu, but for around 60 bucks they are great motors.

The 6mm shaft and 30mm bolt spacing with m4 thread will deter most, but I have had the shafts turned down, and found 6mm bore pinions too. I made my own motor mounts as well. These are great motors, but will most likely have some issues as the cq is not as good as a high end motor. Buy 2 and you will most likely end up with at least 1 good motor...

The same 35k rpm max rule as the feigao have applies here too. Considering the sixe I would try to keep the rpm around 30k max. That should cure any magnet glue or material failures. Plus at that rpm they will run cooler. I never got my 8L and 10L over 150 in the gtp, and it was geared for 50+.

I plan to run a 8xl on 6s lipo in my 7th scale car with a 2 speed. Gearing it for 90 in 2nd. I think it will pull the load just fine, hopefully the MMM can keep up.
