I was unable to reply to this question earlier because I had not glued it all in place at the time. Even when the materials were dry-fitted you could feel the change in the stiffness.

I am please to report that the result gives an amazing difference. The stiffness is very acceptable and even enjoyable :-).

Looks good, Eric! Did you replace the tailpost as well or did you leave it as stock? Did the foam ladder stiffen up the fuselage at all? I'm planning to do one out of balsa instead... I've mounted the stabs but haven't put the former in YET - will do that shortly. I did notice that the fuse does flex quite a bit when I grab the stabs and wiggle them around... so I'm hoping that the crutch will stiffen it up quite a lot.
