I also recomend cutting out a slot in the body to allow cool air to flow onto the solder posts. The wires can also act as a heatsink of sorts but the benefit is minimal.

I'm working on a new wheeler and I'll posts pictures when I'm done with it. I've switched to Losi's and have a XXX4 to finish up.

On my previous car(Yokomo MR4bx) I had the esc on the opposite side of the chassis faced forward. I had fashioned small ducts that routed air right onto the solder posts. I used some scap lexan. I saw 1-2 led's cooler then without them.

Using 2 cap's can also help cool the unit. Since the current crop of wheeler encapsules the electronics in a cocoon of lexan and carbon fiber it's hard to manage heat. So try to manage airflow. You not only have to get cool air in,but warm air out.

I'll post pictures of my XXX4. I've been told that this car and body poses some "interesting" electronic issues.

Oh yeah, nice car too!
