MXLR Fan Holder for Awesomatix A12 (1) - MAX-09-019

This is the final version of the prototype that Max Mächler used for his World Cup victory in 2023. Using a 30mm fan - powered by 6V from the receiver - was definitely not a disadvantage!

It is not easy to integrate such a large and powerful fan in the A12 - but smaller fans than 30mm were not an option because no performance should be lost. At the World Cup itself, Max used a very significantly modified fan to fit it under the body. After numerous tests and further versions, a solution was found that required little to no modifications. The fan was placed further forward and mounted more steeply on the holder. The key to success in getting the airflow where it needs to go are the small side covers.

The result of using this holder together with a 30mm fan at 6.0V voltage is a significantly reduced motor temperature.
Depending on the track layout and grip conditions, this construction reduces the temperature by 12-18°C.

The MXLR fan holder is 3D printed - made of a very durable material that is able to absorb shocks up to a certain point.
The tests did not reveal any defects during departures. In the end, however, it remains a 3D printed part with the appropriate sensitivity - there is still a risk of breakage during departure.

The goal was to construct the holder as light and at the same time resilient as possible. Without the fan and screws, the part only weighs 2.6g. The use of M3x12mm aluminum screws is recommended (not included, but available from RCK) - in conjunction with a 30mm fan (also not included).

TIP: Do not overtighten the screws. It's just plastic!

The total weight when fully assembled is approx. 12g - depending on the fan used.

Longer screws (M3x12mm, not included) are required for mounting on the side carbon plates.

Depending on the battery used and the shims underneath the plates, additional shims may be required (not included) to adjust the height of the fan holder.

The OR230 O-ring may no longer be needed to hold the battery in place as the fan holder itself holds the battery in place.

Depending on the mounting position and the height of the body used, the fan should be able to run freely and not touch the polycarbonate.
In tests with the most commonly used bodies (AMR, Ponente, M20), it was only necessary to slightly sand away the corners of the fan on the M20 to make room.

With GT bodies there shouldn't be any space problems at all.

A notice:
Please don't forget that this product is a product from a 3D printer. So you can see layers and lines of the material.
MXLR strives for the best possible quality and therefore uses 3D printers that are able to deliver this - but a 3D printed part will always differ in surface finish from a milled or sprayed part.

A notice:
The images from MXLR may show additional parts or cars that are not included in the scope of delivery and are only intended to illustrate the application with practical examples. These parts are not included with the item.
Before using MXLR products, it is very important to read the general safety instructions
