OK I need to know what I'm doing wrong. I tried to get this airplane to
fly with no luck. Here's the scoop: The plane weighs 12.5g w/o rubber
w/prop. The plans do not indicate a CG, so that's one missing factor.
I'm using 1/8 " rubber. Prop is 10"d X 12"p. What is a competitive
target weight,and how much prop do I need and what size rubber. Do I
need to rebuild.Where can I save weight? I would assume the wing spars
would have to be fairly hard. When I slice ribs there doesn't seem to
be much strength because they always seem to break using straight grain
1/32". I have used rolled motor tubes and solid,but with 1/8 inch
rubber craming in the winds, I'm afraid the motor stick is going to
collapse.
