what is better for cooling brush hoods and the can of the motor? aluminium or brass....aluminum is way easier to work with...and it seems to have better heat flow....
Brush hoods would be brass, cooling coil would be aluminum. Just because aluminum won't solder . . . well, I don't think it will, I've never tried :) If you have problems with the aluminum not picking up enough heat, use thermal grease. Makes a huge difference since the amount of heat transfer is limited by contact area of the round tube to the "flat" surface of the motor.

"If you have problems with the aluminum not picking up enough heat, use thermal grease."
Please excuse my ignorance, but what is thermal grease?

it is just a goo the helps transfer the heat from the can to the coils better... also there is the thermal adhesive from rumrunnerhobbies.com and it will glue the coil in place and do the same as the "heatsink grease" you can just go to radio shack and pick some up it's like $.99 for a small tube and you don't need much! if u use to much it will get all over! thats y i want to try that adhesive but have never got around to it!

if you remove the torque ring, then tightly wrap the tubing around the can, when you put the ring back on it will be very snug, use either method 'venger suggested adhesive/heat sink compound, and your set, you may also put some battery pack heat shrink aroud it snug it and then shrink it, this will keep the goo on the inside and the ring tight, here is a good thread
and there are quite a few others, put "cooling" into the search bar, cheers eddie
BTW There will be a set of polished cooling coils and some other neat stuff offered in the raffle hint hint LOL
Dan, man this is contagious.....
