Composite-ARF Yak-55 SP (2.6m span)
In a 'positive' paint job some effects can never
be done. Just think about the shadows, peel
backs, highlights, and 3D effects - and all with
a perfectly flat and uniform surface for opti-
mum airflow and aerodynamics.
Truly hard to do, but still possible, are the
paint jobs which seem to be so simple at first
glance: Schemes with straight lines and
stripes. Quite easy with positive painting, but
it's very hard masking the lines in the negative
moulds, because we cannot assemble the
parts before masking. To get the stripes lining
up exactly at the rudder, wing and cowling
joints is therefore almost impossible. This is
why we suggest using thin vinyl trim to make
sure that these stripes line up perfectly.
Sometimes it is necessary to do that, and it is
definitely not a quality problem or a "flaw". It
comes back to what is possible, and what is
impossible.
If you want to have a really
perfect paint job, then you
might decide to have a sin-
gle colour version and have
it painted by yourself or
your friend.
But don't forget: Consider
the additional cost, consid-
er the additional weight,
consider that even if it is
painted 'positive' there will
be areas you won't be
happy with.
Of course you won't com-
plain, because you created
these flaws yourself... !
