Paul,  can  you give me the exact locations for the lower center engine

Thanks,  Jerry

Here is your drawing and a drawing of what I did.
My drawing shows the holes inside the front motor mount brackets
but it will work just as well with them out side the brackets.
Here too is the firewall dimensions that came with the KIS Cruiser.

Unfortunately I don't have the drawing on the position of the brackets
here so perhaps Charlie can send you a sketch. Maybe later today I can get

that

info.

If I understand the drawings, it looks like a high posibility of
interference with the Cruiser nose gear and linkage. I would
strongly suggest a mock up to check this - Vance.

I'll do a 3D shortly Vance but mine clears fine with the diagonals
inside the two nose gear brackets. See the pictures I just up loaded.

And here are yet more pictures.

Is there anything that would cause interference if you put the two interior diagonals outside of the lower gear attach points.  As it is, it has to be basically a precision fit to make it fit inside those brackets.  I'd like to make things easier on Jerry if it is possible.

The draw back is the brace angles for the diagonals are less than ideal. Again
it also tends to put an S bend in the firewall itself when side loads are applied.
However side loads are small unless you go about kicking the rudder a lot or do
aerobatics. This is mostly theory as the Kis firewall is very beefy indeed
in this area and will accept considerable local bending loads.
