Gentle Lady (oz2359)
About this Plan
Gentle Lady. Radio control tow/slope glider. A classic glider trainer. Plan also shows optional power pod and alternative nose installation for .049-.10 engine.
Quote: "Carl Goldberg's Gentle Lady, a 2 metre sailplane. Guide and mentor of so many thousands of modellers through his world famous free flight radio control and control ine designs, Carl emerges from Californian retirement with a glider that will surely become a standard recommendation for years to come.
How has it all worked out? A real pleasure. Gentle Lady is a sweetheart to fly. She really is gentle, and a lady. She reacts quickly to lift, can circle very tightly without falling off, trims out easily, can really go when necessary, is very respon-sive, and yet so stable I've been able to put the transmitter down right after release from the tow and she'd fly herself all the way down. What more could I ask?
I've been impressed, also, with the beauties of glider flying. It's great to be able to take just the model and a transmitter and go fly off a nearby slope! Guiding a trim-looking ship as she sails quietly and smoothly along, high in the blue, is a neat experience. Then when you get home, there's no worry about oil dripping on the carpet. Yet, glider flying is definitely a challenge - far more than I would have guessed before. Searching and finding lift, learning to be sensitive to it when it's very light, staying in the lift instead of flying out of it etc - it's all going to take a lot of flying to develop the skills.
Equipment we've used including Futaba FP3S with S20 servos, the EK brick, and the final model has the Kraft KP3AS with KPS 14 servos. All the equipment has worked without problems. Obviously some weight can be saved with small servos such as the 520's, or the Kraft KPS 18's. The battery we've used has been a 450 mAH, whereas a 225 would obviously save a little weight, too. However, since the battery is in the nose, it would be important, if using a small battery, to also keep the tail end light. Without any special effort to keep the tail end light, only 1/2 oz of additional nose weight was needed. If a heavier skid has been used, no additional nose weight would have been required.
The Sanwa or Acorns 2 channel radio would also work fine. If you want to use the tray for the servos, you will need to widen the fuselage in that area about 1/16 in.
Before we get into the actual construction, let me mention one additional thing. If you have a small car, you obviously will want detachable wing tip panels. This option is shown and although quite simple and light, it works very well. The final prototype has this feature..."
Update 20/04/2017: Replaced this scan with a clearer version (at 400 dpi), thanks to JJ.
Update 21/04/2017: Doh. Have had a good look at this now thanks to Gene, and I think he's right, the previous plan was better. Switched them back again. The JJ plan is now available as a supplement alternate scan. It may be higher res, but it's not any clearer.
Update 29/01/2019: Added article (by Carl Goldberg), from Model Planes Review 1980, thanks to RFJ.
Update 01/04/2020: Added kit review from RCM, March 1981, thanks to RFJ.
Update 15/03/2021: Added kit intructions, thanks to Pit. Note this includes parts ID sheet on page 4 which shows all printwood parts at small scale.
Note for a later, electrified version of this design, see Electra (oz6614)

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

User commentsSteve, I am almost finished with a Gently Lady Glider built from your plan archive. Thanks for providing the plans. The plan did not include the wing rib templates. I found this was a common problem on the www. To finish the model I drew up a complete set of ribs in CAD and would like to make them available to everyone. I used the #9 wing rib shown on the drawing as the template for all the ribs. A PDF version is attached.

My son is trying to print out the plans at work. He has a question about scaling and unsure of how to size the printout. Can you lend any assistance?

I'd say start with the FAQ page at https://outerzone.co.uk/faq.asp#printoutplan then try the knowledgebase pages on working with PDF files, like this 'Checking the page size' one: https://outerzone.co.uk/knowledgebase/entry.asp?ID=105

Thanks for the reply. He printed it out and let the print size select automatically - got perfect size prints. Appreciate all the plans you have collected here. Wanted the GL Plans for 'in case' once I start flying my GL again. Have an Olympic II partially completed and new plans will be much easier to read.

* 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.
