Does an 80" Eindecker qualify?  Almost I guess because right now it is waiting a major rebuild.   

By the way -  what does giant scale have to do with Control Line Scale?  I thought Giant scale was an RC term.

    

For some reason I have stuck with bigger scale models. All were converted RC models.  The biggest problem that I have is the larger airplanes need more room to fly right.  My first shot at the Nationals was a converted RC Extra 300S with an OS max 55.  It simply would not land smoothly.  I converted it back to an RC and it lands great!  As an RC it has a 100 yards to set up a glide and the wind is not changing directions.  My current project is a Brodak La-5 profile.  Bet it flies great and lands great.  It will be light and is designed for Control line.  Also remember we have a 20 lb and 1.25 CI limit.   Oddly enough their isn't a limit on electric size.  Bet that rule was written before the current crop of electrics came on the market.  Hobby King has a 6000 W electric equivlent to a 50 CC gas burner.

Anyway big is fun but too big doesn't fit the circle and fly well. Especially on a windy day.

 

1/4 Scale is a group of scale RC people/group/organization.  Giant Scale is another group.  Two distinct groups.  I remember a distinguished RC Scale modeler that was asked to speed at a 1/4 Scale Banquet.  He brought his newest plane that the name eludes me now.  It was a biplane with only a 48 inch wingspan and was enclosed single seat design.  


Thanks to a fellow modeler, I need to proof read a little better.  It is either the keyboard,  my fingers or the brain that keeps messing up.  I meant to say "speak" at the banquet.   Hope you all will forgive me.  Just think if I started getting senile.
