The plane in question is a Half-A with 185 sq inches and weighs about 14 oz. It has a 34 in wing span with a 5.5 in chord. The wing loading is about 10.5 oz/sqin. I land it dead stick since it has no landing gear. It glides as well as my 2 meter sailplane when coming in for a landing. This isn't really a bad thing execpt I fly it from a soccer field, a very short runway.

My Q500 planes are about 16 oz/sq in and my 40 size pattern plane is about 23 oz/sq in. This seems to be a big spread, I thought there might be a magic number to shoot for, but it may depend more on what the plane is intended for.

I designed my little half-a as a pylon racer. I have since cut the wing down to 30" but have not flown it yet. My thinking was this would increase wing loading and also increase top speed due to less frontal area. I think in this case it was just to much wing area for the weight. Are there any guidelines for this design issue some where?
