REFLECTOR: Do Plans include Carbon Fiber "Y"?

[Don Johnston]

Al, Dennis and Jim,

 

I'm still trying to figure out where this "Y" is. If the two arms meet that
far back, they'll either be cut by the NACA's or they'll go over the NACA's.
If you have to cut them, then you've lost the benefit. If they go in after
the NACA's and lay on top (from the inside) then I would worry that when the
engine goes on and they start taking a load, they could force the NACA ducts
up.

To Al & Dennis,

 

I have a carbon fiber roll cage12" wide that runs down the overhead??from a
Y about 18" in front of the?engine bulkhead ?that connects to the very heavy
triax layups for the engine mounts?to the overhead of the front window and
down into the lower fuselage along the front of the door beams and is tied
across the middle between the door rear carbon beams.? I covered all of the
overhead carbon with a wider strip of Kevlar containment in case the cage is
over stressed and shatters into the sharp carbon pieces.??Mounting the
engine did not in any way alter the shape of my fuselage that I can detect.
