The leading edge of the stab on the original is indeed closer to the leading edge of the fin, but that's because the stab root is set higher on the fuselage on the original, not because the stab is bigger.

You can see this in that side view pic. Extend the line of the fuse top deck past the stab on both models, and compare.

Also check out that three quarters rear view pic. You can see that the original has more anhedral on the stab and the stab root is set higher.

The actual size of the stab seems to me to be about the same.

I guess that keeps the centre of the side area of the stab at about the same height on original and reproduction Curare, which makes sense if they wanted to reduce stab anhedral without affecting other qualities.

They seem to have kept the wing dihedral the same, so all they have done is reduce the effect of the stab anhedral without affecting much else.

The effect of the stab anhedral is to provide a roll-in moment with top rudder in knife edge, to counter the roll-out moment from the wing anhedral, without transmitter mixers which didn't exist when the original was designed. So if the reproduction requires less roll-in from the stab in knife edge, all else being kept pretty much equal, this means the reproduction has a higher centre of gravity than the original. This might be because the original was designed and set up with a tuned pipe weighing about 200 grammes hung under the fuselage, while the reproduction is designed for electric power or i/c power without a tuned pipe.
