I'm not 100% sure (email them and find out). All I know is they ship stuff Via EMS and they only charge what it costs them, no more. If you only bought the Much More unit, It wouldn't be much as it would only be a small package.

For around here the colder you can get the motor the better during the summer. The Team MM cooler doesn't do much at all! We have had a few guys make some that would in 10 mins. put frost on the motor mount!!! I don't know what they used but they are awesome! I got one from guy in SoCal and it works better than the MM one. Not as cool looking but cooler!

Honestly, I have to say I am suprised. His power supply could have not been up to snuff. He could have had a bad unit. If you drop it or give peltiers a good knock, they break and can easliey be damaged. It could also be extremely hot in his area.

My Team Much more unit will get the motor to 30-35 degrees in about 15-20 minutes. But then again I race indoor carpet in the midwest. I can definately see others needing more cooling though. I would get Jeff (teamphariswheel) to see if he would make you one then. His were very chilly

My first cooler would get down to about 9-10deg C on the motor
It will get condensation on the motor clamp





Now I have a heatsink twice as big on it with a 60mm fan and that gets icy.
All up cost me about NZ$60.

My MM cooler also doesnt cool very well... even indoor carpet racing it takes an hour to drop the motor into the 40 degree range... I am going to rework it... just use the lower portion and put on the larger peltier and heatsink/fan I picked up..
I have a couple of friends that have a MM also and while they do cool they dont cool well or fast IMHO

Theory of cooling goes something like this:
* Fan work better when blowing cooler air, it's denser.
* To get maximum efficiency, the warm and the cool go in the opposite directions. Like 2 water pipes soldered together, warm water flows in one direction through one pipe, the cool water flows in the opposite direction through the other pipe. This is the principle that most heat exchangers work on.
* To get maximum cooling, the coolest part should contact the warmest part directly.

I personally feel that you are better off mounting a small fan that blows on the motor endbell during your race. Much more makes one for $10.

I rigged one up for running outdoors mod on a fairly open 100+degree track. It cooled the motor up to 40 degrees less after a run than without the fan.

Plus with a very cold motor to start, you may experience a greater degree of perceived "fade" as the motor warms up.

The motor cooler I made gets to it's lowest temp in 10mins, the trick to getting it to work properly is to make sure the motor clamp is actually fully in contact with the motor can.
I use the fan kit on my TC4 as well as the motor cooler before my races, the motor cooler definitely has an effect on the power & consistancy of the motor, and the runtime.

The cooler you can get the motor before the race the cooler it will come off.

I have also had an opportunity to have a look at a MuchMore motor cooler and they look much the same and get very cold, cold enough to be uncomfortable to hold onto anyway.

Actually I am inspired to build my own mainly from reading this thread. I figure $50 or under seems like a better deal than one that sorta works for $100. If I wanted to run 2 or 3 classes I would need something that got up to speed right away rather than an hour or more.

I found everything I need to make a copper one, now it is just waiting for all the pieces....
