I suggest leaving the span limit open, and put on a weight limit instead. There are several different ways to establish an optimum span for a given weight, and leaving that open lets us explore all of them.

It would be disappointing to see RES tech go to molded carbon ships to get under the weight limit. The whole beauty of RES was the rules opened up so many opportunities with wood models.

I agree. An F3-RES style requirement for fairly simple construction and materials, other than local reinforcements from mass-produced sources, seems to be working in practice, and would make sense. Even so, I would not assume that you have to impose some arbitrary span requirement to meet a specific max weight.

It would certainly be interesting to see what can be built with balsa and simple composites with no span or design limits aside from weight.

Hi Don and Casey,
I agree keep the weight as the main restriction and not the span;
Have designs be constructed similar to the current F3RES - i.e. primarily balsa with CF reinforcements;
Launch method a hi-start but perhaps with less line and rubber to make the contests more manageable;
There can be some tasks similar to F3K with shorter high starts: i.e. AULD; longest 3 flights with 6 launches; etc.
Could be interesting and a good competition venue not to mention the design possibilities!

Hi Corky,
I wish so but Philip B and I are the only ones doing F3RES in Tucson that I know of. I'll have to go to some of the contests in Phoenix once things settle down at the UA.
Take care,
Ray
