Mark,
I think you will find that about 90% of
the engine, PSRU, prop weight will sit on the two front ears of that plate. That
is very close to the CG for those items.

design
Well I think I have designed my mount for the Glasair. Overall I
think it will be a bit overkill but I am ok with that.
Should put the CG close to the same spot as for the Lyco. Thrust
point in the same spot. Green bars were part of the Glasair mount for a
Lycoming. (There was also one between the two upper points but I don’t think
any of them are truly necessary with the stabilization of the plate.
Yellow bar I am calling optional at this point to make it easier to work
with intake/exhaust. Another idea we had was to weld on a flange for both
sides of the yellow bar and have it bolt on during final install.
