Dual fan 40mm Brushless 1/8 RC

This mount is designed to fit two 40 mm fans onto 1/8 motors with a diameter of approximately 42 mm

The dual-fan configuration is arranged as follows:

-The side fan pushes air towards the motor;

-The top fan draws it out of the system.

It optimizes motor cooling, keeping it at lower temperatures during intense use, especially during a race. An excellent solution to ensure high performance and prevent overheating when the motor is pushed to its limits.

For those seeking cooling efficiency without compromising space or weight, I have used this system in my 1/8 GTs for years, keeping temperatures below 90 degrees Celsius even in summer.

NOTE: I have included three files—2Partitions, 1Partition, and NoPartition—so the mount can adapt to all motor mount and chassis types.

Assembly instructions:

Insert eight M3 nuts into the designated recesses;

The fit is precise, and you will need to use a long M3 screw to pull them inside. Adhesive should not be necessary to hold them in place (insert the screw into the hole, screw the nut onto the screw head a few turns, then pull the nut toward the recess. Once in place, begin screwing, and the nut will move into position);

To secure the mount to the motor, use a standard cable tie, passing it through the designated holes as shown in these images;

Now you can insert the motor by pushing it inside the cable tie;

Tighten the cable tie, and the mount is complete. Only the fans remain to be screwed on;

After various tests, I recommend mounting the fans so that one pushes and the other extracts air. Compared to having both push, you gain 5 to 10 degrees Celsius less on the motor.

I recommend printing at least in PETG due to its temperature resistance. I also provide my profiles in PA and PACF, in addition to PETG and PLA+ (only if you want to experiment, but I advise against it).
