Our 5pc heatsink pack is ideal for adding custom heat sinks to your ESCs. Better heat dissipation allows your speed controllers FET chips to operate at a higher level of efficiency. Each heat sink can easily be cut to length with a standard hack saw. The pack also includes a sheet of thermal silica film (heat transfer film).

These heat sinks were a big disappointment. They have a heavy coat of baked on paint on all the surfaces. Heat sinks are always plain aluminum, or anodized to give the aluminum some color.
The heavy paint coating on these aluminum pieces would make them a very poor heat sink.
I tried to remove the coating, but all the solvents I tried would not remove the coating.
Not good. In the trash.It is very handy and helpful for any project. I bought them to add to my antenna booster. This item really do its job. Cheap and high quality.
Thanks Hobbyking.Several of these were convex. A convex heat sink is about as useful as... something useless. Don't buy these unless you check them carefully and are prepared to return them.I've ordered this item multiple times, as I'm always modifying my ESCs so they can tolerate the extremely hot conditions of the Phoenix, Arizona, USA area. Both the extrusions and the thermal transfer material have always held up quite well. I would recommend this item to anyone.Love this bulk pack!! Im use it to cool many things!Great pack. Using these for video TX cooling so I can remove the case on those heavy 1.5W 900mHz TX'sBe mindful that the heat film that comes with these is not adhesive. It's more-or-less useless. To attache to an ESC you will need adhesive transfer glue. You can use CA around the included film with some success.Well made heatsink. The weight are:
43g (51X80); 36g (39X80); 24g (25X80); 13g(39X30); 8g (25X30).
sempre utili, esc motor ecc eccGood quality heatsinks. But the silica heattransfer isn't adhesive. Coolingfins on heatsink complies with the same width fan screw holes. Very easy to screw the fan on the element. Applicable fan max 50x50 and min 20x20.
