I went through a pile of Windsock datafiles and pulled out the
following figures for some fullsize WW1 aircraft. I also tried to
find the article about power loading in "Radio Control Scale Aircraft"
without success. I just ran my finger down the TOCs trying to identify
the article, no luck I am afraid. However the following might make
an interesting comparison with experiences and perceptions of "scale"
flight for R/C models.
Of course power loading isn't everything. If a prop has zero
efficiency ( eg a feathered prop) it will absorb 100% power and produce
no thrust. Similarly nominaly the same spec props for models will produce
different amounts of thrust with the same engine (or electric motor).
Thrust also varies with speed of flight as well (if I remember
correctly). Anyway here is the list:
