Is the metal spar wing
a bunch of engineering hype then? No, not at all. As well as
the engineering aspects of the convertion to metal spar wings,
there are other practical reasons to consider a wing swap.
(1) It is typical for
a retro-fitted airplane to retain the added value of the metal
spar wings. Aiding this fact, new fabric and paint methods in
the industry offer more durable covering that looks new for
years. Also, the assembly work is done by the factory under an
FAA approved quality system.
(2) The wings are ALL
new parts. That is, new ribs, new fuel tanks, new control
cables and brackets, everything! Most sets require new front
struts as well. These struts are "Decathlon Style" with a large
