I have a Laser 2000, (78" wing, 17lbs, and a G-62) that has a wing loading of 32.54 oz. I know how to arrive at that number, but how do you know if it's good or bad? Thanks in advance for any help, or advice........

That's a little high for that much wing area, but should still be a nice-flying airplane. Your problem is in your engine selection; if you can get a lighter engine in there it will fly better.

jbflier, if that Laser 2000 is from Kangke the wing span is 87". Mine weighs 16 lbs 4oz and it's very light on the wing. You should have no problem at 17 lbs.

Outcast; Thanks; it is the Kangke Laser. I just got my 7 & 8"s backward. "87" is right, but I'd still like to know how you determine what's light or not. Is there some sort of scale or refference to go by? I know for my kind of flying, (sport)
the G-62 will be more than enough. How do you like your Texas Hurricane? I really have had a ball with mine this year. I have a G-38 on it. It probably could use a G-45, but my G-45 is on my Sig Sukhoi. Such problems, eh?..................

Thats a pretty stiff number. I ca,me out with 33oz on a DC prop jet.

Check out a site I use .They have a wing loading formula that works on wing volume not area. In my opinion I have found it to be fairly accurate prediction of flight characteristics.

go to giant scale then wing loading do the math and let me know if you think it gives a reasonable answer . try the numbers with something you are flying now. I would like to hear others responses on this idea.

You have a loaded question here. Wing loading is somewhat dependant upon the size of the plane. A plane with a 48" wingspan would not fly very well with a wing loading of 32 oz/sq ft, but a plane with a 105" wingspan would be more like a kite at that same loading. I think, and I can only say this from my limited experience, that you should have a pretty decent wing loading for the plane you have. Wouldn't have been my choice for an engine on an aerobatic plane though. Something like the BME 50 would have equivelant power and would weigh much less yielding a slightly better loading.

Unfortunately there is no "scale" to judge wing loading. Lighter is usually better but there are so many other things that effect the way a plane flies. You could have two identical size and weight planes, if one has a 12% thick airfoil with a sharp leading edge and the other has a 14% with a round leading edge they will be VERY different planes. Some people like to use "cubic loading" and based on that the laser is very good, but it to can not compensate for all the variables.
As far as the Hurricane, the new one is powered with a Brison 3.2 and its very over powered, I think the 2.4 was probably a better match for the airframe but it does fly great, and it will accelerate vertically like it has afterburners.
