[NSRCA-discussion] Weight limit in AMA classes

Fri Dec 11 17:04:27 AKST 2009

 Very little carbon, good ol balsa and ply. A key thing is a gram scale because you have to weigh EVERYTHING.

BUT you must know how to build...that is THE ESSENTIAL element. You must not be at the mercy of arfies

Hummmmmm!  
Building a modern large 2 meter pattern bird at 9 lbs wouldrequire what kind of high tech materials and technology? 
How many would have one of these?

That's what I was going to say.  Smaller is moredifficult to fly, so why not?

Very simple statement.  Open your checkbook if thispasses.  Big 2 meter bipes will be the norm.  YS will come out with a50CC size engine that blows away other gas or Nitro setups, and much bigger,more powerful electric setups to remain competitive.  People thing thiswould reduce the cost, it will do exactly the opposite.  You are rightDave, there is no competitive advantage to a plane of the size we are flyingnow being 11 1/2lbs, but be able to build a 13lb bipe with unlimited power andwatch what happens.

Yep!  I've got a G-62 laying around here that I have nouse for--until now.

Excellent! Looks like I can finally build a  gas-powered biplane. LOL

I have submitted a rules proposal to completely eliminate  the 11 lb. Weight
  limit in AMA pattern classes. (proposal 11-11).
  I'd like to see some discussion on the pros and cons of this proposal on the
  NSRCA e-mail list and the Pattern forum.

  My reasons for submitting the proposal include the following points:

  1. There is no competitive advantage to a heavier plane with the 2 meter
  size constraint (in fact I'd argue a heavier plane is usually at a
  disadvantage and perhaps a minimum weight makes more sense than a maximum)
  2. The 2 meter size constraint is sufficient keep the weight of pattern
  planes to reasonable limits.
  3. The fact that AMA class planes are weighed only at the US Nationals gives
  proof that the rule is not now enforced and not needed.
  4. The 11 lb. Weight limit drives up the cost of pattern planes through the
  necessary use of more expensive high tech materials. (If you don't believe
  "light weight" cost a lot of money ask the people who race sail  boats)
  5. Removing the weight limit will reduce the manpower and cost associated
  with running the Nationals And also perhaps increase participation.

  OK, guys, what do you think?
  What other "pro" and "con" points?
