Kraton Modified the ESC fan and fan housing

[Rpmspeedyblue]

Kept collecting a lot of debri. Notice the fan keeps trapping the debri between the ESC heatsink. See if this helps preventing all the clutter.

Had a very similar problem, and had a very similar idea, but I left the fan inside the housing on the heatsink, took another old fan and gutted it so I just had the square shell, mounted piece of fine mesh window screen on top of that with a nice fan cover on top of thatView attachment 1674 [/ATTACH] I usually do the same thing with fans on motor heat sinks as well.

Put a chunk of window screen over the top of the esc. Cheap as hell and works great. Haven't gotten a blade of grass or anything in since.
