3D model description

Parts to make a semi scale Continental dummy engine for a roughly 1/4 scale Cub. The dummy is designed to duct air into the cowl. The size may need to be adjusted to suit your model, because of slight differences in cub models. The model can be resized to fit bigger or smaller models. I have made dummy motors for 1/3 and1/5 scale Cubs myself.

Parts include:
Left and right cylinders with exhaust tubes, intake tubes and pushrod tubes.
Baffle covers for ducting air over the cylinders.
Cylinder covers.
Gas cap with a hole for a brass tube.
Intake box/filter.
Exhaust muffler/end tube.

I use thick CA glue to assemble the parts.

For personal use only, not for resale.


3D printing settings

The parts fit a 200x200 mm area as supplied.

I printed mine from PLA.
I printed mine at 0.2 mm layer height.
Two outlines is enough.
25% infill is enough.
Support is necessary under the exhaust tubes and filter box.
