Yeah very scientific:005:

I agree,just channeling the air across the esc is what i'm thinking of doing.I was just messin' about really,it's kind of the way i think out loud.I think the air will probably manage to 'dodge' the scoop at these low speeds.

There's no direct route for air onto the esc on this truck unless i raise the esc to the level of the windscreen,that might be the best way to go,with a lexan 'box' between the windscreen and the esc.And maybe an exhaust channel straight out the back too.

I've got some heatsinks coming too and some thermal adhesive,i'd like to try to get away without a fan if i can and just use more heatsink and find the best way to channel as much airflow over it,like you say.
