Hobbywing C4 Motor Heatsink & Fan Combo
Great buy for the price. Using on my castle 1515 2200kv motor. Requires some bending to fit the motor.)

Hobbywing C4 Motor Heatsink & Fan Combo
These are made out of good quality for the price.
The fan is really good and large (40mm)
However the motor heatsink do not fit on Castle 2650KV motor. Also it does not fit well on slash 4x4.
I recommend the fan but not the motor heat sink.)
