revo motor questions

[gasshead]

the only time i have had to use fans was on my rc18. but it might be because i am running a 1/10th esc with a 8 cell pack. i dont beleve i wil have a problem with overheating and if i do i will go look at some computer shops maby rob a heatsink from a video card. like i said earler i am mounting the ESC and UBEC where the receiver is in the pictures. i dont belece i will have a problem with this setup. i will probly be running a 8XL, or what ever will give me beter run time and more speed
