[NSRCA-discussion] weight limits for electrics?

Sun May 14 20:20:51 AKDT 2006

Yes, Some of the pattern guys would go to the hassle of a bipe to get the
competitive advantage of the bigger plane - and the rest of us would be less
competitive unless we chose to spend more time and more money (assuming we
had the time and money to spend - and some don't and will drop the event).

Yes 96db is a challenge for gas, 94 (FAI) is even more of a challenge.  Both
can be easily done - it only takes $$$$

Restructure the rules so that the most competitive airframes are more
expensive, more complex, and require more time, and the numbers interested
in the event will drop (as it has every single time in the past when rules
allowed escalation of the airframes).

The IMAC guys don't want to deal with it, but pattern guys would?  Only
motors that would support bipes in that size are gas.  96db at 3 meters?
Now there's a hassle.  The skys not falling.

Yes they are a PIA and I don't want to spend the extra time either.

IMAC essentially has no limits, excepting the AMA 55 lb limit which is not
really a factor.

Bigger flies better, period.  If an IMAC guy went through the fuss to build
the monstrous bipe with wingspan similar to the big monoplanes, it would be
"bigger" and it would fly better.  No one wants to deal with that hassle and
expense.

A 2M bipe is bigger than a 2M monoplane.  The 2M being bigger will fly
better, period.  And it will be more expense and it will result in some
number of current day pattern competitors leaving the event.

I don't buy into the bipe theory.  Bipes are a PIA.  I wouldn't want to
spend a half hour setting up and tearing down every day I went out flying.
If bipes are so dominating why don't you see them on the IMAC circuit?  They
don't have any size or weight restrictions and they strive for the same type
performance we do, yet they're a rarity.  They're nice to see and may show
up, but a flight line full of bipes, I doubt it.

Any time a limit has been relaxed; there has been a change in airplane size
and or design.  It is not necessarily immediate but technology seems to
adapt to the new limits.  Just try to fly one of your 2M designs with a
piped 60, or even a 120 4C.   When 4C limits were increased to 1.2 cubic
inches nothing changed.  Some brave folks tried 4C but it didn't work until
YS came out with a 4C engine that was more powerful than a 60 2C engine.
Then the planes took a step larger and heavier.  When the engine limit was
removed planes got larger again.  120 AC engines were now only good for the
beginner classes. (An oversimplification).  Right now the weight limit
works.  Yes it is a bit harder to make a 2M pattern plane come in under 5 kg
when made electric but it can be done.  A gas engine 2M may be even more
difficult.   Relaxing the weight limit will make it easier for an electric
conversion to make weight and make a gas powered version more feasible.  But
new designs will now show up pushing the new limits.  The obvious direction
is a 2 M bipe.  A 14 pound 2 M bipe may present better than a monoplane,
maybe not.  If it does then everyone will "need" or at least want one.  If
people want to try something new and bigger then scrap the weight limit.  If
not then relaxing the weight limit to fit today's problems will have
undesirable effects tomorrow :-)

I understood that the definition of model airplane states that weigh has to
be below 5 Kg.  That is consider international.  The only exception is the
scale that is a little higher.  I am not sure if this single reason is going
to make difficult to change the rule for F3A.  For sure is going to help the
gas engines.  I don't think electric power plants are having a weigh
problem.

This subject has been adressed officially. Based on what I have been told,
the weight limit for F3A will be dropped with the next rules changes. What
will remain however, is the 2M by 2M box.
