I need the weight and balance points for the early Super Cub, enclosed cowl,
no flaps, and I believe soloed from the front seat. Can anyone tell me the
front and rear points of the envelope as measured from the wing leading
edge?

Thanks for you help.

Check the aircraft paperwork -- it is a part of the required p/w for the
plane. It may not show the datum as the LE of the wing, however.

After you get that info, it easy to construct a X&B program on Excel and
determine the CG for any combination of loadings.

I am building a Light Miniature Aircraft wood and fabric Super Cub. It is
full size without flaps. I was hoping someone could give me a general idea
of the weight and balance measurements to check what I got from LMA.

Since it isn't a super cub and probably used a different airfoil, has a different weight, one can't use it to check on the "look-a-like."  It will be close but you are kidding your self if this is your approved data for your ultralight.

Here's another one of the good guys in the group.   I insulted him once when he picked on one of my favorite English novels, but you see him in a lot of the other groups, doing what's best for homebuilders --- helping out with friendly advice.   I applaud him and apologize for the smartass remark I made to him.
 
For the lurkers and others building or contemplating it, people like him and Jim Weir are national treasures.
 
However, if he's publishing in HTML, shame on him.   LOL!

shame on him too for referring to this heavy two place as an ultralight,

it doesn't even meet the sprot pile it requirement of 1232 pounds
gross,,,,,,,,,

Hi,

A cg from 25% to 30% of the cord is normaly working for a plane like a cub.

Thanks for all the input. This is not an ultralight and airfoil is the same.
LMA saysCG at 25% of the chord but they are a little vague about how far the
envelope extends fore and aft.

Thanks again to all.
