Subject: Front Cover motor mount

I might now have them backwards. I'll reason it out again now. The
engine rotates CCW looking at it from the front. With the 2.17:1
psru the prop rotates CW. So the major torque down load is on the
left side looking at it from the front. Right side from pilots
point of view!

Opps I screwed up, No biggie I will leave it where
it is for now. Don't want to make another bracket. However
if I find a piece of suitable T extrusion at my local surplus metals
place I will make another better bracket for the left side looking at
it from the front. Right side from the pilots point of view. Have not
made the tripod yet.

Thanks for checking me on that Ken.

BTW we should start using port and starboard. What side does the
pilot sit on? :-)

Paul,
The reason that this caught my attention is that I was planning on a
single rear mount on the right / rear.  This mount will be very lightly
loaded - My front mounts will be 1" behind the rear housing (of course,
this is the front of the engine when mounted on the airplane) so most of
the weight will be on the front mounts.  My calcs showed only ~40 lbs on
this rear mount.  Will a 2202-12 Barry mount be optimal or should I go
up or down a size?  I also planned on a 2202-13 for the front left and a
2202-14 for the front right. Sound OK?

PS - PLEASE do not use Port and Starboard!  For those of us in the
middle of the country there is no ocean in sight and will never be able
to keep it straight. (grin)

Sounds OK.
By all means go down to a 2201 for the rear mount. Life will be easier.
