In fact I'll do my best to save more weight. that might some times be difficult to choose between a stronger structure or a lighter airframe. But as Matt said lighter weight always brings you best results.
Before starting the project I reviewed your Tipo 40. But I prefered to use a glow engine instead of an electric onecos from my point of view though it has less power than an electric motor in this size but can betterreproduce the sense of a classic pattern.
there is one question left: did you hollowed some windows in the wing core or not? cos itreally weighs well. This is what I couldn't see in your tipo's pics.
