3D Printed Motor Mount for 45mm motors, 60mm Length
3D-Printed Motor Mount for 45mm motors, 60mm Length
When installing electric motors into aircraft, you often need to come up with a way to move the motor forward to get it in the correct location in the fuselage. Many modelers today are also converting their older glow powered aircraft to electric power, to take advantage of the simplicity and consistent power output that electric motors offer. However, in most cases, the electric motor being used to replace the glow engine is significantly shorter, and this creates the problem of how to mount the motor and have the prop end up in the correct location. To solve both of these issues, we have designed a series of 3D-Printed Motor Mounts that move the motor forward the desired amount while providing a convenient way to mount the motor to the firewall.
These mounts are 3D Printed from rugged PETG plastic and come in a variety of lengths to suit your specific application. Included with each mount are four M4 x 10mm socket head screws to attach your motor to the mount, along with a set of 4 spacer shims that can be put between the mount and firewall to fine tune the length of the mount to get the perfect gap between your prop or spinner and the front of your fuselage. The spacers are 1mm, 2mm, 3mm and 4mm thick, so they can be used individually or stacked to add anywhere from 1 to 10mm of extra length to the mount.
The 45mm Series mounts were designed to fit the BadAss series 45mm motors and feature a 30x30mm mounting hole pattern. The design of these mounts includes angled cutouts that line up with the air hole exits on the back side of the motor for good cooling air flow. These mounts will also work with other brands of motors with 40 to 45mm stators that have a 30x30mm mm mounting hole pattern, such as Tempest, Cobra and most other popular brands. The slotted holes in the base of the mount will accommodate screw hole spacing between 56 and 64mm.
Special Note: The PETG plastic used to make these mounts is dimensionally stable at temperatures up to 170 degrees F (77 degrees C), which will hold up well to normal use. If you leave your model in a hot car in the middle of summer on a sunny day, the temperatures inside can exceed these values and can cause deformation of the mount. Treat your aircraft with the same care you would with your kids or your dog, don’t leave them locked up inside a hot car!
