Full wing spar for SPAD 3DT?

I am building the SPAD 3DT, and I am currently at the part where I need to dill the hole in the fuse to then force the 5/32 music wire through BOTH the wing and the aluminium fuse (this is the major difference between the 3D and the 3DT). In the instructions it says cut the spare down to 18", but if I just left it at 36" (which is also the width of the wing) would that have any negative effects on it?

It would add a little more weight. I have the Spa3dt with the shorter spar and I've never had any trouble with the wing flexing. I don't fly mine fast although. It doesn't like to fly fast. I usually fly it around sort of "hanging it on the prop."
Also in my opinion, I think the normal spa3d would fly better as it would be lighter with the U channel fuse. The Spa3dt seems to be heavy with the square tubing fuse. Just my 2 cents...

I'm using a 12.25x3.75 prop on a Magnum XLS 46.

I would agree, with the planes the ailerons and elevator will get shadowed by the air slip stream if you go too fast with them. They were intended to fly around slow. But it is great slow flying and hovering practice though.

Here is mine, I am running a 12x4 prop on the Fox .45 engine on it.
