The Fokker DR1 Dummy Motor

Printing and assembly of the dummy motor.

She's gorgeous but not exactly to scale. She's scale enough to look convincing under the cowling, though. she does a great job of concealing that this airplane is in fact electric.

The Crankcase:

This is the start of the dummy motor build that holds all the other components. the mounts for the crankcase were modeled separately so that it can be printed with the rear of the crankcase flat on your build plate.

The Jugs:

The cylinder heads were designed to not require support when printing. These can be printed upright like in the image. Make 9 of them.

The Pipes:

Unfortunately there just isn't a straight spot on this component that lends itself to an ideal printing orientation. You will definitely need to print with supports on for this. While your at it, you need to print 9 of them.

The Mounts:

The four mounts printed separately can now be adhered to the back of the crankcase with CA glue.

The Real Motor:

The motor rendered in this image is a GOOLSKY C2216 1120 KV motor. It fits within the crankcase of the dummy motor assembly.

Mounting up to the Fuselage:

The real motor should have been installed first. Now the assembled dummy motor can slide over the existing motor and mount and be bolted in place using (4) 3mm x 12mm hex head screws.

Conclusion:

That is it for the dummy motor! Check the main blog here for the next steps. Feel free to reach out to us with any questions. We will attempt to clarify the construction blog including your input as much as possible.
