DKKY 42mm RC Cooling Fan Motor Heatsink 21000 RPM for Axial SCX10 Traxxas TRX4 Slash/Rustler/Stampede/Bandit Arrma Kraton Mojave Senton 1/8 1/10 RC Crawler Car 4274 4268 Motor, Black

This is the perfect fan for 2024 model Maxx Slash 6s no modifications needed

Hooked directly into my ESC and it works great. Didn't measure motor temps but seems to help keep things cooler.

This fan is awesome, especially for the price, it fit my new maxx slash perfectly and kept the motor real cool! The color changing light is cool too,just do it!

Strong but little bit bigger for a vxl 3s motor Still does the job and looks great

Doesn't fit TRX-4 Titan 550. Says TRX-4 right in the description. I'm posting a video with this review. Watch it. UPDATE: So, I separated the fan from heatsink, added a washer between fan & heatsink at every hole. Reassembled. Now you can put a couple zipties through it & pull tight to secure it to motor. I raised review to 3 STARS because it works fine & matches other red trim. Also, I overlooked the engine numbers at the end of description that says which engines it fits. Once I seen TRX-4, I reckon I quit reading. My bad. UPDATE AGAIN: After the process to make this heatsink w/fan & lights (which I didn't carefor, at first) after 3 battery uses, by the 4th, both quit working. Sometimes the fan works. Sometimes the lights work. Most the time nothing works. Back to 1 star. Only because I can't give it 0 stars.

I was having problems with my 36 50 motor overheating cuz I was running it on 4S and big gears big tires and this thing cooled it off nicely.

did 4 stars because I haven't run the RC yet, the bracket on heatsink fits loose so I put some shrink fit on prongs. works great, waiting on other parts, will update.

Good
