4 Pack Vgoohobby Aluminum Electric Engine Motor Heatsink Cooling Heat Sink Fins for 550 540 3650 Size Brushed Brushless Motors RC Car Truck,Blue

Worked great for my son's robotics team that needed to help keep a Gobilda moto cool

They fit perfectly on my kids F-150 Power Wheel's electric motors. They snapped right on and looked like they fit tight to the motors. As precautionary method, I added some thermal paste to them for better heat conductivity between the motor housings and heatsinks.I bought these as a precaution since I plan on converting it from 12v to 24v. Hopefully they will cool the motors enough to so they last longer at double the voltage.

Works but doesn’t stay easily on theMotors

4 for the price of 1? It’s a no brainer.Works well. With this product I can now touch my over geared 550 21t brushed motor after 2 full 3s 2200 packs. Don’t take it the wrong way. The motor is hot, but not burn your f’n fingers HOT without it.

They can come off but what do you expect for $10. Bend them back. Throw um on and go.

Super glued these to 570 motors that kept overheating on my kid's ride on. No heat issues since. I was surprised how effective they are. Thanks

They are much smaller then they look in the photo, yes you pay for what you get they also do not stay on the motor, I bent them several times then finally to the point the almost broke and the still pop off be prepared to buy some thermal glue if you want to get these to actually work.

It fit but you can only put one on. I was hoping to put one on each side making a full wrap.
