Static testing motor mounts is always a problem as one must come with a 1000 pounds or more to test it at 6 G down as would be experienced in a hard lading or minor crash.

Normally the fuse can be used to do this by applying a down force on the tail and a car or truck.


With a ten foot long 4 by 4 we have a mechanical advantage of 8 so in theory we
can lift 1600 pounds with this rig. I'll test it by jacking the Honda Odyssey.
In theory it will move 9 inches up.

I can't over estimate the advantages for this approach to motor mount
design. It holds the promise of drastically cutting the cost of installing a rotary engine in a wide range of aircraft. Getting a motor mount fabricated and shipped has always been a thorn in our sides.
