I agree that the BEST way to have a light airplane is build your own
but it not the easiest. Those of us who competed back in the dark
ages know how to build and finish a balsa builtup or balsa/foam
wing and work with a raw fiberglass fuse. <br>
<br>
We now have a lot of participants who not only do not have a clue
about building a wing or finishing a raw epoxyglass fuse, they are
even reluctant to assemble one of the current breed of ARFs. If they
tear out the gear, they need help getting back in the air. Options
are more limited for these folks and they do not all have unlimited
resources. They are part of our pattern community and are some of
our more avid pattern competitors. They have a lot of respect for
those who can build but they are not willing to put in the hours
through the years we spent acquiring those skills.<br>
<br>
While there are many, myself included, who could build pattern
planes today we choose instead to buy. This is often a time vs
money decision where my time is more valuable to me than the dollars
I send to the Chinese. For others, it is not a choice- buying is a
necessity. If you don't know how to build light and straight, you
certainly do not know how to repair light either. It is this part of
our pattern community that I would like to help with an increase in
the AMA only weight limit. If you like, it is those just starting
out and those that are financially challenged that need help with a
weight allowance, not you and me. And those are the flyers we need
to help if we are to have any chance to make pattern grow.<br>
<br>
It seems very clear that the world-wide pattern airframe industry is
driven by the FAI weight and size limit. That we here in the US
increase our weight limit, as other countries have, will not impact
the designs and airframes commonly available at a reasonable cost.
Who is going to design a heavy airframe and expect to sell it? 50cc
biplanes? go ahead and build your labor of love that has no market.
If I practice every hour you spend designing, building, modifying
and testing such a beast, I will be way ahead. There is no magic
bullet in any airframe much less a heavy one regardless of power
plant. There are many planes that will execute a wonderful pattern
if straight, light and properly trimmed. That is a fact of life and
not a rule.<br>
<br>
Being able to have the freedom to raise our weight limit is only
made possible by the FAI specifications of a pattern model. If the
FAI, in its infinite wisdom, were to raise either the size or the
weight I will be right there helping to fight it as that change
would bring on all the airframe change and added expense that many
are concerned about.<br>
As a point of interest, the Intermediate and Advanced class
attendance at the 2011 Nats increased by about 50%. Was this caused
by the 115 gram allowance for those classes? I don't know but I very
much doubt it hurt. for comparison, Masters was up 34% and F3A 21%.<br>
<br>
Cheers<br>
John(another grumpy old man)<br>
maybe because we don't build enough anymore?<br>
or still have ambroid and dope withdrawals?<br>

<div><br>
</div>
<div>Not to be confrontational but some of that is simply not
true. The EASIEST way to make weight right now is building your
own with traditional materials and techniques. A simple built
up balsa wing will save more than half a POUND (10oz) over a
composite wing. A balsa/foam wing is slightly heavier but still
saves a full 8oz. We've been building fiberglass Fuses since
well before I started in this in the late 80's and the only
change to the fuselages is layering some carbon in to stiffen
the nose and gear area. Nothing magical there.</div>
<div><br>
</div>
<div>The issue is somewhat the opposite of what you present.
People don't WANT to build, they want to BUY. </div>
<div><br>
</div>
<div>But even that is no longer a real issue. Are there some
heavy planes? Sure. But a lot of the current planes on the
market today make weight without issue for electric and anything
glow seems to not be part of the discussion even though those
aircraft are perfectly viable. </div>
<div><br>
</div>
<div>Bottom line is that weight is a constraining factor. BY
DESIGN. Without the constraint, designs and equipment WILL
change, and that change will cost money and that will eventually
be passed on to everyone. <br>
