Quote: "Hi, I have experienced that none of the usual sources have Sophisticated Lady plans. Forum requests for the plans have not been fulfilled. Here is the original ...CG fullsize kit plan as PDF. WS is 78-1/4 inches. Had it scanned at my expense, it's my pleasure to submit it. An interested builder could readily find all the part templates. Tapered outer wing ribs can be generated by any experienced builder..."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

I see the formers are incomplete on this plan. I seem to remember that the Soph. Lady uses the same wing as the Gentle Lady. One of the plans for the Gentle Lady on your site has the formers.

The Sophisticated Lady uses the same wing as the Electra - the electric version of the Gentle Lady [here on Outerzone: Electra_oz6614]. Both the Sophisticated Lady and Electra have more wing sheeting and internal bracing than the Gentle Lady. The Gentle Lady wing may well serve on the Sophisticated Lady, but it would not stand up to quite as much aerobatic stress, being more lightly built. That being said, the wing airfoil shapes and plan form of all 3 versions remain the same. Perhaps when I get to building my kit of the Sophisticated Lady I will trace all the wing ribs individually. In the meantime, someone else might be able to provide wing rib shapes? Cheers,

Added some really nice pics of this model, thanks to Luc Daigneault [more pics 003-005].

* 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.


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.
