Apex RC Products 1/8 / 40 Size Motor Aluminum Heat Sink #8039

Fits the Spektrum Firma 4074 2050Kv motor in the Kraton 6s v5 BLX perfectly.

Works great and reduces motor temps without the added weight and complexity of a fan system. I use this on a 1/8 truggy during races, so keeping weight and battery usage down is important.I’ve modified mine by adding extra fins for more surface area and heat dissipation, but it’s always worked well in stock form. Bit too long for a 4274 motor, but it was easy enough to cut to the correct length. Holds on strong and never falls off. In fact, it’s a little tough to remove.

The media could not be loaded.  What a good job of cooling it does WITH 2 higher powered fans !!!This is in my Kraton 6s wrapped around a STRONG RCRunning 4076 2000KV brushless motor.

These work well and even better with a fan. Keeps the motor cooler for longer runtimes without over heating.

I'm running an ARRMA Typhon TLR with the Spektrum 2050Kv motor. I needed to give it just a slight bend to slip on the 2050 case. Really soaks up the heat and fits inside the TLR chassis with room to spare.

Works great on my Castle Creations 2200 kv 1/8 scale motor in my modified Traxxas Stampede! I had previously tried a fan unit, but it kept getting stuck when running in sand at the beach. So this large-finned heatsink does a great job keeping the motor cooler without sand getting stuck in the fins. Definitely recommend.

This monster heatsink generally is enough for my 6s trucks and don't need fans.

Used this for my kids power wheels stock motor to help prolong the motors life after upgrading her car to run on 24v battery. Seems to be helping as she drives it consistently full throttle without any issues. We’ll see which goes out first, the motor or the wheel bearings. Both have been reliable so far. I recommend these heat sinks.
