I have both the RCM magazine article and a copy of the gentle lady instructions.

I was going to scratch build one from the RCM plans, but then found the kit instructions/plans at an estate (R/C only! ) sale. I got a deal on a Spirit kit and put the GL on hold.

I recommend buying the plans from RCM and you get the article with it for under $10 shipped.

I could also scan or xerox the Goldberg instructions for you too...
