I dug up a MAM diagram for the 0-235 and I believe it is the same mount
for the 0-320. It shows one degree of right offset and zero down thrust.
However you might check to see if I put anything in the archives (as I
often do) about 8 years ago. Reason is because I measured a conical
mount and my less than perfect memory recalls 1 or 2 degrees of right
offset and 1 or 2 degrees of downthrust. I can't find anything
definitive in my notes. For low power cruise with the soob and wing
cuff, the down thrust and offset was a good thing to put in my mount
from what I've seen. However I would not hesitate to use 1 or 2 offset
and zero downthrust if I was building an 0-320 mount.
If guys are cruising your configuration with the top of the door opening
level then I think that would confirm zero downthrust is perfect. I
would aim for the thrust line level when cruising with whatever reflex
flaperon you expect to use. So that may be a question to ask the list if
you still need the info.

I have started to build a mount for my 160 hp Lyc. engine,
I have all other dimensions that I need except the down thrust angle
that MAM uses? Does anyone have that information, or know were
I can find it?
Thank you Keith P.
