Review: Required modifications - The first thing I noticed when I installed it; it would not power up. Before I would decide to return, I crossed the wires, the fans turned on. I had to strap it down with a zip-tie and had to use a dermal to cut away a piece of aluminum for the screw that tightens the motor. Other than that, it works great, keeps the motor cool, and has not had a thermal shut down even in 105 Texas Heat. The sound is a little loud but sounds awesome. Have gotten compliments on it while at my son's races.
Review: Good bang for your buck - Great RC fan setup I’ve used them on 2200kv mamba monsters and also sketrum 2050kv motors they move a lot of air and help keep the motors cool. Very power fans, they are pretty loud they work well with 1/8 scale motors.

### ⭐⭐⭐⭐ Not perfect, but great nonetheless.
*by J***Y on October 12, 2025*

While they dont directly fit tightly onto the VXL-3s system on their own, a couple zip ties and your motor will run very cool. They are very fast and so far despite being held on by Walmart zipties, its held together well and has kept my motor cool running 3s lipo batteries and monster truck tires.
