I don't get it with the pictures, they worked for a few hours then stopped.

I'll use the castle link to tune the esc as I have to get one to set the voltage on the CC BEC anyway. Besides it's a good oppertunity to buy something I need from the RCM store to support this site, which in my opinion has a value all it's own.

I was pondering the "wind tunnel" setup for the esc boards (actually made a 3d model out of folded paper to set in the car--- I'm how old? hehe) it occured to me that I wouldn't get any cooling air flow on the channels of the heat sink that are pointed directly at the hub of the fan.

Do you think a mesh screen say 4mm from the fan would difuse the flow enough to keep the coverage even?
Mabe if it was concaved (funnel shaped) with the center cut out- say the same diameter as the fan hub? Any ideas on how to difuse a 25x25x10mm fan in the shortest length possible without excessivley restricting flow would be welcome at this point.

Also are there caps available that will do the same job as the 3 330uF 35v caps but take up less space? I could also see the caps restricting flow but I don't think it would keep the "wind tunnel" from working. Just curious...
