[NSRCA-discussion] weight limits for electrics?

 I agree and didn't Chip do this and it didn't take hold and stay around for long.

  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 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 J

    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.
