[NSRCA-discussion] weight limits for electrics?

[Stuart Chale]

It may not be Bipes but a change in the weight limit would certainly open
the door for a change.  Maybe we are currently flying the best plane that
fits the patterns and still is under 2M, maybe not.  I think it is just
likely that someone might find something that flies or presents better
within the new rules.

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.
