Guys,
A nice Gent by the name Peter from Germany has been dealing with 3D Printing and produced a scale 9-cylinder Engine Bust model that actually allows the Stock E-Flite 15 motor to go through the cavity of the Engine.

Here's my comments about the preparation of the parts from the Frame Molds.
1. Instead of drilling and other tools per the instructions, I have used an angle hook Pick Tool that was very effective in the cleaning of the main Engine Housing.
2. The Cylinder Push Rods need careful handling so as not to lose any because one of mine was ejected and flew a few feet at a location that was easy to recover.
3. Otherwise the instructions are very very well written.
4. Instead of CA, I am using Gorilla "Clear" Glue and it has been with great results.
SUMMARY:
The Pick Tool did a super and fast, effective job in cleaning up the inside of the main Engine housing.
This is by far the best Engine Model that I have ever come across and the quality is very good for 3D printer.
EDIT:
I am having great results in using the Gorilla "CLEAR" Glue!
Does NOT leave any residue, pretty much fast cure (comparatively to others) and it is CLEAR and does not look like there is any glue what-so-ever.
The warning label says to watch out for fumes but, I don't smell
