Good question Craig - my DUMAS 18" Spad 7 biplane has a wing loading of 0.53 grams per square inch of total wings area.  I only got a 10 second "swoop" over the grass - but then again, I never put 2 degree positive incidence into the lower wing, and I never put 1 degree positive incidence into the upper wing, and I never put negative incidence (decalage) into the stab.  I did try a downthrust shim in the nose, to no avail.  But it is still a rubber powered free flight model, because the prop is hooked up to a rubber motor, and the kit is advertised as a flying model.  I "intended" to fly it, but I did not know all of the tricks ("one man's flyer is another man's brick", I think I read a wise man say ...).  I think I read that a 20 second flight qualifies you for the Flying Aces Club.  It seems to me, that there is a fine line between too heavy to actually fly, and light enough to fly.  But then again, I am no expert.

Max wing loading?

OK, I know .5g per square inch of wing surface area is the ROT- but how high a wing loading have you guys actually gotten a "successful" flight with? Lets call "successful" for the purposes of this discussion 20 seconds with a proper climb and decent descent back to terra firma.

I'm looking at some of my old Cleveland plans- reputedly they'd fly, but manoman, some of them make me wonder. I guess I'm trying to determine if there is a go/ no-go line above which it is definitely going to be a static build.

On a related note, I have a minty fresh wartime Cleveland Master Kit FW-190 with wartime "replacement wood." I think, if one built it from the kit, it'd gross over a pound!
