Subject: Renesis Remote Mount Oil Filter

The stock renesis oil filter pedestal is very tall.  Tracy Crook used a
3rd-generation (FD) pedestal on his Renesis.  I found that the
intake/output holes don't align exactly -- so he probably honed out the
block before the engine was assembled.  This is hard to do once the
engine is built.  Also, the other generations of oil filter pedestals
won't fit (only the FD and Renesis have the ancillary oil line
takeoff).

It may be easier to just mount the filter remotely.  It is pretty easy
to make a piece of 1/2" 6061 that fits over the engine block holes,
which are about 0.4" ID.  Tapping the block out to 3/8" NPT allows a -8
fitting to be used, without any reduction in the internal diameter.

The FD oil filter pedestal can be mounted almost anywhere.  Using an
angle bracket gives a lot of options.  For Paul:  Is 1/4" 6061 with
3/8" NPT threads strong enough to handle the 100 psi or so from the oil
system, or must an angle bracket be made of thicker material?

Thanks

Hi Scott,      Just a suggestion while your in the planning stage: If
you mount the filter can horizontally some oil will remain in the can
and you will need to catch it when you change the filter. If you have
the opportunity to mount it vertically, gravity will drain the oil
effectively one way up or leave the can full the other way up. Either
way up will make oil changes more manageable and if their easier to do
they'll get done more frequently. Remember oil quality is especially
important to the rotary in aviation use.                    Dave M
