"Powered model aircraft performance may also be estimated by calculating the
weight / power ratio, also known as power loading.
A slow and low wing loading (for a beginner), with a weight / power ratio of 440
to 500g/c.c. (270 to 300oz/c.in.) might be good enough, whereas an aerobatics
would need about 340g/c.c. (200oz/c.in.) to achieve good performance.
This is assuming 2-stroke engines and that the power of different types is pro-
portional to their displacements, (which isn't too far off)."
