Arrma BLX Motor Heatsink
Fits pretty tight to the motor, would suggest a little thermal paste to fill in between the gaps of contact. The fan noise is not crazy loud but it can be heard. Overall decent heat sink, but a little over priced.

It seems fine and good quality...fits nicely and does the job...can easily mount a fan too. It also touches the chassis so it provides additional heat conduction through the chassis and provide more support (seems like it).

This heat sink will fit a 42mm diameter motor, however the combination of the heat sink&fan attached will not fit in a arrma vendetta. After I put the sink on the motor, I couldn't get it in that rear input gear where it meets the transmission gearing.
Shame...

Great heatsink option for the Arrma 6s line. Sort of tricky to install because getting that spring clip on there can be quite the chore, but at least I know it holds well.

Arrma BLX Motor Heatsink
I crammed it on a Castle 1515 motor. It required some modification to do this. The portion of the heatsink that fits under the solder tabs had to be ground down to fit.

I like the large fins and I think it works better than other brands. Even without a fan my motor never gets hotter than I can touch it. This one is installed in my 6s Arrma Notorious, I plan on getting another one for my Kraton EXB.

I'm happy with it's performance and recommend it.
