What would be a goog wing loading for a 60" 120 bipe that will not cause it to sink like a rock on landing but yet keep it aerobatic?

A good wing loading for this plane would be somewhere in the low 20s(oz. per sq.ft. or under, but remember with a biplane there is more lift ,but double the drag!! For What it is Worth

The lower the wing loading the slower it will land. the lower the wing loading, the tighter it will turn. The lower the wing loading for a given size wing and engine, the lower the weight will be and therefore the better the vertical performance. Lower weight for a given size will also limit acceleration on the down line which will make it easier to fly some maneuvers. The only thing that might improve with a higher wing loading is lower response to gusts. For a given wing area the biplane can only produce roughly 80 or 85% as much lift as a monoplane. Therefore, low wing loading is that much more important for biplanes.

Now that is interesting. If a wing has the same area (surface and frontal) does it matter if it is a Bipe or Mono? That is an interesting question.

Comparing the lift of a pair of biplane wings and a monoplane wing totaling the same area, airfoil and aspect ratio, the interference between the biplane wings reduces the maximum lift that can be generated and increases the drag. How much the interference causes decreased lift and increased drag depends mainly on the gap between the wings. The more gap the smaller the interference effects.

OK, makes sense.
Thanks Ollie

I see a lot of the aerobatic mounts including the GP Pitts are running between 28 and 31 oz. Is that a reasonable number?

Thanks? Found my own answer.

I am old and slow so I like less 9:1 wing load elec of course
allmost rubber band type. I have one bird I call Floating Flower CU
