LOSI LST XXL Conversion ideas - RC-Monster Forums

I looked at that one for my build, but I don't have room for those fins with my rear bulkhead brace. So I've been working on a custom heatsink made from flat, square, cpu sinks!

edit: I want to know how the heck that rock got in there too.

I still don't have the answer to that one.

I received my CC BEC today. Nice little thing, I replaced the blue heat shrink with a stronger one that has glue in it and has a shrinking of 3 to 1. So now both ends are sealed around the wires and will keep dirt, dust and water out of it. Now to decide where I will put it on the truck. I thought of just sticking it to the MMM with double sided tape. Since I don't use a switch, I cut off the part of the MMM mount that houses the switch so there is a space on the MMM casing behind the caps that looks big enough to stick the BEC to.

The CC BEC is installed and it's working great. I updated it to 6 volts and I noticed the difference on the steering servo. Quite a bit faster and torquey. I like it and it was easy to install. I chose to stick it to the MMM because when I need to remove the ESC, the BEC just comes with it. So does the cap bank the way I have everything set up.

Hello,
this kind of temp seems to be normal as the hot weather, the weight of the truck and the no-finned can. Try to open your body, airflows can change everything !

The motor gets plenty of air flow so what it needs is a means to dissipate the heat using that air flow. So I'll take it easy on the motor until my Losi heat sink arrives. I'm hoping it will bring the motor's temp down enough for me not to worry about it anymore. This motor won't last very long if I run it at 200 degrees all summer. If this large heat sink can drop the temp to 180, I'll be happy. Any lower and I'll be very very happy.

There are some that may not agree with this but I did a few things to seal the openings of my NEU motor. I know the holes in this 1521 motor can offer some airflow to help cool it but where I run the truck, I don't get airflow, I get dust flow. There was way to much dust and debris getting inside the motor and bearings. So I sealed the rear with Goop around the wires and a piece of flat Lexan stuck to the motor with servo tape. For the front, I made a disk out of a thin piece of aluminum with just a hole for the shaft and two holes for the screws. Air can still get in and out of the motor but it is restricted. This should make it very difficult for dust and debris to get inside the motor. This is something I am trying here, I need to see if it will change the temp of the motor while running this way.

I use aluminum tape to do the same thing on mine. Not sure where it can be bought (I get it from work) - but that stuff works great in certain applications like this.
