I agree its nasty to pay a cars worth on a esc but we still come in cheaper than a fg comp or a losi with a after market motor if we run a redcat. Brakes add 20% to 30% more run time so says mcd. Most people would trade the slight advantage of a esc braking stopping distance to get more run time. So I would also like to see brakes on 1/5th scalers as it really does help get that run time. I'm sure some one in the industry is taking notes off your build:)

What was funny, is in the video I actually forgot to hook up my brake servo connecting rod after I got the body on. It still was easy to drive, but that's on a track ;)
 
I tried to stretch my heat sink around the 5698 motor but I did not have as much luck as RCDad, so I continued on w/ my original idea.

Here's the start:

I just need to trim the fins a little ;)
 
I have wanted to get a mill for over 10 years and finally pulled the trigger at the beginning of this year. I had been using my drill press w/ my dremel in a vice to do 'mill' type work. It pushed me over the edge, I wish I had gotten the mill many years earlier. The size of the one I have is not that big but plenty big for this stuff. It's not as small as a sherline or round-column mill but it's not nearly as big as a bridgeport. For the price you cannot beat it, I'm sure I'll save money on rc parts alone to pay for it. I also sold a bunch of rc's to pay for tooling.

If you have any inclination of getting one just do it, you won't regret it.

Yeah, you deffinately have me thinking about it. You seem to be able to do a lot of custome parts.
 
I'm sort of winging this one guys. I don't have a very good plan. I figure anything to dissipate the heat has to help. I think I should shorten the fins but when I see they fit under the roll cage I question why. Also I'm not sure where to put the fan. I could put it on top blowing down or maybe on the bottom blowing up or even in front or back blowing in the direction of the wind or no fan at all would be the easiest.

I just have the fins on the motor, they are not all connected yet. I also think I won't run the cowl if I keep the fins tall like this.
 
With out much surface touching the motor case I'm not sure how much heat you can pull away. Maybe if you had a lot more plates.
 
Well this sort of takes the steam out of this build:

Unfortunately, Fear Farm R/C Raceway will be stopping all operations immediately. I received word from the owners, that with the upcoming holiday season, they will not have resources to continue racing. I am hopeful that an arrangement can be worked out, so that even a partial racing schedule can continue but I can not make any guarantees.I've been graced with many new friends from this facility and I truly hope we have not see our last days racing there. Thank you to all that have helped with the operations and a huge thank you to the racers!! In addition, thank you to Robert and Ken for all their efforts with Fear Farm R/C, so many great memories have been made thanks to you.

Again, I hope this is not goodbye Fear Farm R/C and I hope this is not goodbye to my FF Friends.

I know usually they alter the RC track schedule during the holiday season (i.e mid October - Jan) but simple halting all access in mid September seems unusual. I hope you're right but I'm also hoping for another option.

Sounds good! I've been looking at some mini mills online. Any suggestions?

Looks good. The more contact the motor has with the heat sink, the better. You'll want the fan to blow into the heat sink for better cooling.

To narrow your searchers, eliminate anything w/ a round column. I know some say round columns are fine but there have been many times I thought to myself how bad it would suck to have a round column.

here is a round col:

here is a square col:

round columns cause you to loose your position if you move the piece/head up or down.

here's mine:

The picture is deceiving, it's only about 4' tall. I had to build a stand to put it on.
