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.....
