It's good to have an educated opinion on the mount design and

know where

it's  strong, weak, heavy, etc.

 So far I hear:

 1. The mount could be cheaper to build
 2. It's got some extra parts that add weight but no strength
 3. Two seals for the oilpan = more probability of leaks
 4. The lower truss design causes increased compression stresses
 5. There is little support for lateral movement
 6. The CG picture is arguably confusing

 While all of these are valid criticisms it's difficult for a

novice like

myself
to tie any of these to the engine falling off my airplane in a

hard landing.

 The next question is whether this mount has ever been load

tested and if so

under what conditions and with what results? Even is someone is

flying with

this mount that doesn't mean it's safe.

 While Butch's response was a bit over the top it did have a few valid
points,
including the fact that if you don't want to spend alot of your own time
designing and fabricating a mount there isn't a whole lot of choice out
there.

 Just like the bellhousing that George is working on, until

something better

comes along you either build it yourself or accept what's available.

Jerry Hey builds a good mount. Ed Klepis will also build a mount to your
design. If you tell me what you have in mind Sheet Craft here in Santa
Paula will also build a mount. I can work closely with the owner
Bill Mensinger to answer any of his questions as he is a neighbor.
He has completed and flown a modified  Pazmany aircraft design.
He also builds water drop tanks for fire fighting helicopters used
world wide. His prices are very reasonable indeed.
He also does some restoration work for the local antique
airplane community.

Paul,

 Thanks for the suggestions. I'm building a Cozy Mk4 but I'm not committed
to engine yet. My working assumption is that I'd go the turbo 13b route.
I don't have alot of time to invest in engine integration so your mount
builder references may come in very handy.

regards,

Dave Wilenius
