I see another problem Paul. I think the thrust line is about 1.5'' below
the upper longerons. The top of upper longerons is WL 23 and the thrust
line is at WL 21.5". On your drawing the shaft is at about WL26.
Just looked over the plans and think that side bracing to the spar is
possible. I assume these braces are supplementary to the main firewall
hard points. My main spar is in storage but I have the fuselage in my
room. So I measured and think that we have about 28"-30" space from the
center line, for the extra attach points on the spar.
I have attached side and top view of the area.

Does this look about right Bulent. I scaled it from the drawing
you sent. The spar might not be in the correct position
on my drawing but that does not matter much. The most important
is the thrust line relative to the motor mount hard points
on the firewall.
