I made an airplane that is 24.5 inches long, 30.5 inches wing span and 173.85 squared inches of area. Now it weighs 15.6 OZ, and has a SPEED400 motor, and I want to know if the weight of the plane (15.06 OZ) is normal for its dimantions and wing area.
Thanks.

The math works out to wing loading of around 12.9 ounces per square foot.

Easy Star is around 9.4 oz/sf

Wing Dragon 4 is around 10.5 oz/sf

I have assigned a project to make an RC Electric Airplane. Can somebody help me how I can get guidelines about this project from net.

If any body has worked on it and he like to tell me some thing about it I will be really Thankful to him.
