Recommended print settings with a .4 mm nozzle:
- Layer Hight: .150 ~.160 mm, depending on motors and gearing
- 3 perimeters or shells (1.2 ~ 1.5 mm)
- 8 bottom layers (1.2 ~ 1.3 mm)
- 8 top layers (1.2 ~ 1.3 mm)
- Infill 20~30%, depending on infill type
Additional items needed for assembly
- Medium CA or another suitable adhesive
I recommend using medium CA, with or without accelerator, to glue the individual parts to the model. However, feel free to use any other suitable adhesives you are comfortable with.
The holes for mounting the motor are pre-threaded for M3 screws.
The motor mount consists of 2 separate parts - the X-Brace at the rear and the 1.5 degrees Offset at the front. The two parts should be glued together back to back using medium CA, to make one assembly. When completed, the engraved writing should be visible on the front side.
Cut a 42.5mm high X 45mm deep opening in the front of the model for the motor mount, centered along the longitudinal axis or desired trust line. Make sure that the opening is not cut too large.
The motor mount assembly is installed with the engraved writing facing forward – The “Up” should be in front and be oriented towards the top of the model. If mounted up-side-down, the offset trust angle will be in the wrong direction.
Dry fit the motor mount assembly by orienting it properly in the opening with the long rails facing forward, and the short rail pushed all the way to the back of the opening that was cut in the step above. It should be a snug fit, not a tight fit. If necessary, carefully trim the opening in the foamboard.
Once satisfied with the fit of the motor mount assembly, remove it and apply medium CA (or epoxy) in the motor mount assembly rails, then re-install it in the model.
Note: The motor mount assembly is designed with the correct offsets for a clockwise rotating propeller when viewed from inside or the rear of the model. This is the standard in North America and many other countries around the world. Some models may require counter rotating propellers. In that case, the correct offsets should be to the left and down. This can be achieved by mirroring the 1.5 degrees offset part along the “X” axis prior to printing. Unfortunately, this will also mirror the engraved text in front of the part making it difficult to read. However, the direction arrows will remain pointing in the correct direction.
