Calculate the estimated weight of the plane.

Then calculate wing loading you will get a general idea how the plane will fly.

Generally lower the wing loading number, plane will be of floater type.

If this is your first plane you should build one with wing loading below 10.

And try to ask your questions in the same thread you made previously.  Dont make new thread every time you have a question. (This is just a suggestion)

As per the details given

Wing area = wing span X chord = 35in X 6.69in (17cm) = 234.15 sqin
Wing area in sqft = 234.15/144 = 1.62
weight in oz = 15.87 oz (450 grams)
Wing loading = weight in oz / Wing area in sqft  = 15.87 / 1.62 = 9.79 oz/sqft

Your planes wing loading comes out to be 9.79 oz/sqft  which is quite high for the beginner.

Consider another example:

Wing area = wing span X chord = 46in X 10in = 460 sqin
Wing area in sqft = 460/144 = 3.19
weight in oz = 15.87 oz (450grams)
Wing loading = weight in oz / Wing area in sqft  = 15.87 / 3.19 = 4.97 oz/sqft

This plane will fly quite decently, will be controllable and slow flyer.

I have given dimensions in the previous jpeg image.  Consider those dimensions.

Also I have sent you a Personal Message (PM).
