Here are two views of my Oil Filter Mount. It replaces the factory mount
which has the filter sticking straight up. This one places it angled down
about 20 degrees directly above the #2 rotor's top spark plug. It also
includes three "clean oil" ports (two can be seen, at the left) for oil
temp and pressure sensors, and oil supply for a reduction drive and/or
turbo-charger.

This photo is actually of a set that I made for another builder; they are .0625" longer than the plans specification, to compensate for bulkheads that turned out thicker than expected.

Here's the whole MKMG mounting set: two one-piece MKMGA-C2 tubes, and the
four MKMG-4 bushings for the MLG bulkheads.

and for the aileron control rods, I'm making a variant of the CS50,
from 304 SS, that I'm calling "CS50-D". It is dimensionally identical
to the CS1-D.
At 1.375", my ends are longer than either the CS1A or the CS50, so
that the MM-4 bearing can be screwed in it's full depth, if needed.
Also the threads in the 2024-T3 CS1-D are swaged (the equivalent of
rolled threads on a bolt or cap screw), rather than cut - for improved
thread strength and finish.
Having had some inquiries to make parts for people who wanted to
upgrade their control rod bearings from the HM-3/MM-3 to the 1/4"x28
thread HM-4/MM-4, I came up with two other variants to account for
the variety of tubing being used in the EZ series. All are 1.375" long
including a .25" x 1/2" dia. shoulder, and threads that are 1/2"
(2x diameter) deep. Here is a table showing their relative dimensions:
| Part # | Material | Minor Diameter (to fit inside the tube) | For tubing wall thickness: |
| CS1-C | 2024-T3 | .442" | .028" |
| CS1-D | 2024-T3 | .428" | .035" |
| CS50-C | 30304 (304 SS) | .442" | .028" |
| CS50-D | 30304 (304 SS) | .428" | .035" |
