As I think about this some more, I realize that my memory must be faulty

(not the first time I have come to this shocking revelation !!).

Obviously, the wing area would have to be factored into this equation......a

brick could weigh the same as a 2 meter glider, but the watts necessary to

keep it in the air would be vastly different........

Subject: Watts/Weight

Recent discussions regarding how many watts it takes to fly a 5 pound ship

reminded me that once upon a time someone had developed a table indicating

various weights and the watts necessary to fly them..... Of course, the

exact answer would depend on variables such as efficiency, etc.......but

there were 3 ranges given for each weight. For example (these numbers are

made up), for a weight of 3 pounds, the table would show 100-150-200 watts,

where the first was for maintaining flight, the second for mild aerobatics,

and the third for competition aerobatics.

Does anyone know of such a table.......or alternatively, a formula that

could be applied like this ??

Thanks.....
