A Gentle Lady is hard to beat, named after Carl's wife Beth. I've flown many, always a pleasure. I never liked the spar thru the center of the ribs, OK with the kit ribs but a pain to cut from scratch. Wing is also a bit weak, having seen one (the whole wing) flutter when trying to exit a thermal. I would use two spruce spars instead of one, 1/8" x 1/4" laid flat to the surface, with balsa shear webs between, plenty of strength with no weight increase, leading edge sheet balsa top and bottom. Would be pretty easy to add electric power, just delete nose block and bolt a motor on. CG looks a little tail heavy, but it's correct, doesn't fly well if balanced in front of that spot.

Instead - use a wooden dowel or aluminum tube with a matching diameter hole in the ribs. The Sterling kits used the rectangular hole and matching spar also - probably due to the die cutting method of punching parts out of sheet wood and long before cnc.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
