Default something new

I thought some of you folks might like to see something new developed for the QM40 aircraft......

Has other applications too.

Well THAT's a heck of a good idea! That's a concept that looks way cool for Q500's, sport, whatever. I like it. Would you use a third fill line, or loop the fuel line forward and back to the needle valve inlet for fueling access, or have I missed something obvious?

ummmmmmmmmm

Maybe this prototype picture will help explain. You can see why Dub changed to the new design.

Quite a few use a filter or joiner in-line between the fuel tank and shutoff. That way we can leave the pinch-off closed, fuel, and it wont leak afterward.

Others wanted access to the port - disconnect fueling.

So they have a choice here.

Very slick. What's the weight penalty vs a standard mount with remote needle? It looks like the backplate could be thinned at least in the bottom portion.

Capiche , I forgot about the need for shutoffs on QM's. I knew real estate was scarce though. Thanks Bob.

No penalty really considering its use ..... that is the standard QM40 engine mount. The SJ-46 mount is the same, just different mounting holes.

Probably saves .25 oz in the long run by eliminating the remote body and mounting screws

Must be the perspective on the first shot. It looks like the backplate is ~1/8" thicker than the second picture.

That is one very nice motor mount. I see lots of 'sport' applications.
