[NSRCA-discussion] Weight

[Dave]

Bill,

Starting from the position of a well designed plane (with proper wing
loading), adding weight will not provide an advantage.  What the weight
limit rule does is limit the size the plane - larger planes will fly better
which does provide an advantage.

The historical vs current perspective on this discussion point (which is
well covered in the archives) boils down to this - 
- in the mid 1990s, planes with 2M wingspans and fuse length were common,
and none are competitive today.
- there is a difference between a skinny 2M plane of the past and a large 2M
plane of today...the larger plane flies better.
- allow the weight of planes to increase, and you will see even larger 2M
planes (increased cost and complexity) that will obsolete the current crop
of planes.  This would not seem to be favored by anyone, and making the
event more expensive will further limit those that can afford the event, and
reduce numbers in the event.

Regards,

Dave

Subject: Re: [NSRCA-discussion] Weight

 I guess I should make a couple of things clear. First, I am not really 
trying to argue one way or the other, it was just something that struck 
as interesting. I left out structural weight and such for the sake of 
simplicity.
 
I have no personal ax to grind, I fly an electric that is absurdly light 
so I am not trying to do anything there. 

I guess the real question is, what is the objective of the weight limit 
rule in the first place? Is there an advantage in being heavier??
