Weight rules discussion ( my opinion)

[Rcmaster199 at aol.com]

Jimmy, I've read Don Lowe's columns for years and his rationale (one that I  
agree with) is that a light plane bounces more but damps quicker than the 
heavy  plane. 
 
I don't doubt that increasing the DR wing loading by 15% as you  did in your 
experiment, would likely result in better flying fro that plane. It  would be 
more interesting to know what the wing loading was and is before and  after 
the change.
 
Now translate that to a 2 meter job and see what happens. Try increasing  the 
weight of your standard pattern model by 15% and see what it does. How does  
the wing loading compare to your DR b4 and after the changes? 
 
I'd be interested in that experimental result

I  assume you want to disregard the 11 lb limit. You will have advantage over 
the  9.5 lb plane. The 12.5 lb plane will be much more stable in the wind 
than the  9.5 lb plane. The engines of today will handle the heavier plane just 
as well  as the 9.5 lb plane.   The difference is you're more stable because  
of your weight. Now if you throw in the weight limit 11 lbs that makes you not  
legal.
I have a 6.25lb Daddy Rabbit that I had to add 1 lb lead to the CG  to calm 
the plane down so I could fly it smoothly . 
Same thing.   
Don't know if this is a rational reason to be legal or not,but there is an  
advantage to a heavier plane.
