I've seen it but am not sure how well it works. They also say it's belt driven which means that it will sap power off of the motor. It sounds like they are trying to re-use their stupid-chargers since they have such a bad reputation with the nitro crowd.
 
It looks cool, But i wonder how much power it would take away and how well it really works. If it doesn't have a noticeable power difference in the motor and it cools it well it might be a good idea. I would like to see some reviews before i would buy one though.
 
So would it offset the amount of heat it would generate from added resistance to the motor? Would it clog with dirt faster, since it would be sucking in air at 40k+ rpm? Might almost be worth it to give it a whirl, but my motor is mounted sideways, so i doubt it would serve me any purpose.
 
Looks cool but then again so did the stupidchargers....worthless but looked cool. It might work, I am sure it does not take much off the engine power wise.
 
Well, the more i think about it the more i would tend to shy away from it. If your putting such a load on your motors that you need this thing to keep the temps down..... it probably is straining your motor too much anyway. Just looks cool though.
 
Firmly disagree Alpine, sorry.

You have a tiny little rubber belt that's gonna turn two plastic impellers. Let's weigh that resistance versus the motor turning a drivetrain which is gearing a 6lb. truck. The additional resistance is probably less than going to the next larger pinion.

Whether it's "worth it" depends on two things... One is necessity, two is advantage over other forms of cooling.

Having the cooling system directly linked to the motor is going to have a major impact on the cooling ability because those impellers are going to turn waaaay faster than say... a standard motor cooling fan could. The real question is do you NEED to move that much air AND are there any negative affects to the lower motor temperature. Given these two cooling options both have their draw of power. One is resistance to the motor (which means the motor will draw slightly more from the battery to compensate), and two, a conventional fan will draw directly from the battery itself.

Which is more efficient? Is there a necessity?

I would say if you were geared so high that the motor was getting warmer than a conventional fan could help then there may be a need, and considering the gearing that would be in place to reach these motor temps the extra drag of the system itself would probably be far outweighed by the volume of air and cooling efficency gained.

I only doubt there are very many users that would benefit greatly from this. Large oval racing is the only use I could see this being beneficial.
 
I think you might have misunderstood my post.
What i mean is if you have such a strain on the motor already, (gearing, excessively high rpms, too much weight, etc......) that is causing your motor to run extremely high/dangerous temperatures without this application, then your problem isnt proper cooling, but that something is wrong with the setup of the rig, and just cooling the motor down with air wont necessarily solve all of the problems. Running a motor beyond its capability will cause failure, even if the temps are reasonably brought down by this high-forced-air cooling.
 
I think another application for this would be in an electric dragster or funny car. This need to be geared high for the top end. It would also give them a more scale look.

Ahh, I hear ya. and to discredit them further it's obviously being marketed as a bling option. That thing definitely looks more show than purpose.

I don't know. Standard drag racing is 132 ft. and top end cars are doing it in a couple seconds... literally. I guess if you run enough cells that a motor could go from 80 to 180 in that much time??? That would take a phenomal amount of power I would think. However, that would be freakin' COOL!
 
One of these days. Rolex, we're going to have to hold you down and take your RC's out for a bashing......
 
Believe it or not, I'm taking a break from working on my latest project, an E-Savage. The radio gear is in and I'm about to paint the lid. Since I bought it used, it's already got some dust and scratches on it. :whhooo:

I'll be playing in the dirt in less than a week. :p:

I CALL BS! :p:
 
OMG we have a break through, ROLEX is going to drive one of his trucks, HOLY SH%#.
