Hi Ben,
 
even if you can't use one of Jerry's S-beams, he should be able to weld you one of these babies (see attached pics).
Lay them out the way you need them, have some knowledgeable engineer math it and off you go!
Startermount included, and also check the turbo-pack!!
Photos are from an old post on the "other" list.
Richard Martin is "responsible" for that beauty, working for a helicopter project...
 
I have pics, if you need/want them, but these are the most "visible" ones!
 
 
I assume a CCI would do also-sideways, though I do not really like the loadpath of the CCI.
Another alternative is the Mistral backplate mount, but again, I don't really like the loadpath through the engine.
My personal go is something like the pics show - or a S-beam - the load gets picked up there and the engine is left alone.
Keep on mind the pics show a mount for a helicopter project, but I believe it should be possible to get it right for plane inthe same manner, though possibly with different dimensions.

Dale,
Please post pictures of your mount or send them to me directly. I am also considering plugs up on my Acroduster Too mostly to help with inverted flight and oil, but also because a high thrust line is preferred on the plane.
Do you see any negatives with the installation other than not being able to use Jerry Hey's S-Beam Mount?
Do you know if plugs up will work with George's (down under) bell housing?
Thanks!
Ben

Thanks Ed,

   If all it was *ever* going to be was just a test stand, I'd agree
about the precision.  The test stand is as accurate a model of the
COZY firewall, dimensionally, as I can make it (same template).  If
this works out well, then I'll be duplicating the mount for the real
thing - except I'll send that one out to be welded by a certified
welder.  If it doesn't, then I hope CCI gets caught up on the
backlog before next fall (2007).

BTW, most of my ideas for implementing "plugs-up" came from
the photos of your installation.

Dale R.
