About this Plan
Caprice. Free flight towline glider.
Update 20/05/2013: Added printwood formers, thanks to vintage1.
Update 23/11/2016: Found and added the missing final sheet (page 13) to the printwood file, thanks to AndyCoutts. This sheet shows the tailplane rib templates.
Supplementary file notes
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

IMO Nev Willis's KK Caprice is the BEST small (sub-A/2 size) small contest glider EVER. I speak from the experience of having built six and lost three of them. Quite why it is so good is hard to say; there is nothing extraordinary in either the layout or the aerodynamics. The structure is simple with every bit doing the job it is designed for and no excess weight, mine have all weighed between 5.1/2 and 6.1/4 ounces. It just tows beautifully and trimmed for a fairly wide glide circle will float on the smallest whiff of lift. The photo [more [pics 003] shows my first Caprice which, on its very first day out won the club glider cup. Wish I looked like that now - well, with a better haircut!

Hi Steve Andy Coutts here, mailing you from South Africa ( ex Zimbabwe). Firstly let me say what you guys at Outerzone have done in five years is brilliant, you all deserve a huge pat on the back for the time and effort this must consume all for the benefit of your fellow modelers. And for free!!! I started modeling in 1965 as a six year old back in Rhodesia. I followed the same road every enthusiasts of that vintage did, building and flying rubber powered free flight models, 049 control line, A1 and A2 towline gliders, stunt and combat control line, then on to RC as a working man in late '70s. Done it all, right down to owning and running a hobby shop. With two daughters who had no interest in the hobby, it all came to an end in the early '80s to concentrate on sailing. That lasted 20 years till they left home and boredom set in. So I decided to build models again, but boy how the hobby had changed in my absence. Being from the old school I have no interest in the latest Chinese ready to fly stuff and stick and tissue construction kits are few and far between. I purchased a few vintage kits off e-bay along with some Cox engines, then after googling stick and tissue balsa model aircraft I found your website. Heaven. I have come full circle back to where I started 50 years ago, building and flying models from my youth with utmost satisfaction. In the past year I have scratch built many models from plans off your website. See Caprice photos attached [more pics 004, 005]. Keep up the excellent work.

Andy sent us lots more great photos of planes he's built from Oz plans. I'll add them to the relevant pages asap. Thanks Andy :)

The Caprice is coming along well. I decided to build the fuselage and tail out of depron, and that seems OK at the moment. The under fin is 1/16 sheet, but I have covered the fin and rudder with red packing tape, which also acts as the rudder hinge. I learned the technique from 'Experimental Airlines' on You Tube. I built a depron Junior 60 last year, and she is still going strong. I used balsa for the wing spars, but depron for everything else. Flies and thermals very well, and had a few 1 hour flights out of her. Launching the Caprice I am going to mount the motor on a detachable wing pylon so that I can bungee launch her if the park is quiet or use the electric motor if lots of people are about. Attached some shots of the Caprice Fus as of this morning [more pics 006-011]. Wing ribs cut and hope to start building the wings this evening. All the best,

I have attached 3 pictures of the Caprice, which is getting near flying state [more pics 012-014]. I have attached a Turnigy 2730 to the power pod that I am making up. Another over-powered model. It is taking me time to get a feel for electric motors after spending all my life with diesels and later 4 strokes. It seems quite difficult to find brushless motors of smaller sizes, less than 22mm, at a reasonable price. May have a go at making my own. Lots of info on youtube and instructables just got to learn how to do it, but that means losing time building models. The base of the detachable power pod is made of a Millicano coffee can, which is very strong and light and held on to the wing by the rubber bands used to hold the wing on to the fuselage. I did this so that I can leave the pod off if I decide to get the surgical tubing out and have a go at bungee launches. I built the Caprice fuselage from 3mm Depron and was getting very worried that I had wasted my time as I had not put the top decking on as I wanted to fit the servos and radio gear in to get some idea of the balance as I went along. It all seemed very flimsy. As it has turned out the servos could have been well forward of where they are now, but after using 1/32 balsa for top decking, and covering with yellow packing tape, the fuselage is very rigid. The next Caprice fuselage I build will be all 3mm depron with Millicano tin sheet to reinforce the wing dowel area. Should cut the build time down to a couple of hours if I get the folding layout right on the depron sheet.

Good morning Mary, I just took a pic of the Caprice, all ready to fly Saturday morning when the wind speed drops [more pics 015]. Roll on Saturday, can't wait to see the Caprice flying.

I have just returned from the maiden flight of the Caprice and she flew like a dream. The Dartford bridge was shrouded in mist, with a very gentle westerly, about 4 mph. I gave her half throttle and she climbed gently away before almost vanishing in the low mist at about 200 ft. Gave her a bit of left trim to keep her turning, and throttled right back. Had a very pleasant half hour before the battery alarm went off and she came in for a very gentle 'greaser' of a landing. I had had to keep using the motor because of having to fly so low. I will be taking her out again early afternoon, and should be able to get a good 2 hour flight thermalling. The next 7 days are looking flyable for Dartford with low wind speeds and not much chance of rain. The Caprice is such a slow and gentle aeroplane that she will be ideal for my local park. Save taking the car, just an easy 2 minute walk away. I have bought a car video cam from ebay for 10 pounds, so I am going to try powering it from a 11.1 lipo, and mount it on my head to try to make some flying videos. The cat is looking at me through the front window, so I had better go and let her in. Happy days.

I had a brilliant hour with the Caprice in my local park yesterday. Wind was light and variable and the Caprice was in her element, just floating. The park is surrounded by trees with all their leaves still on them, so I had to be careful. I just set the trim for a left hand turn and let her climb gently and remain in the park boundary. once she was up a couple of hundred feet I cut the motor and she gently floated back to almost ground level before I gave her half throttle and away she climbed again. Very relaxing with the occasional 'nudge' to keep her from disappearing.

Went flying with Lindsay on Saturday, foolishly towed up the Caprice without a DT fuse and watched it fly off into the distance. Gone - after twenty minutes it was a mere speck in the sky and I gave up watching. Lesson learnt. Time to build another. Here's my Caprice just before she sailed off into the distant blue yonder [more pics 016, 017]. Thanks again for such a treasure as Outerzone.

In my carefree bachelor days (remember those?) I built a Caprice but never flew it until, after we were married, my wife expressed interest so, one Sunday morning, we took it over to a nearby pasture to try it out. Why are six-month pregnant ladies so reluctant to trot across a field towing a model glider?

I finished off the replacement Caprice and it flew beautifully. I have to concur with Sundancer - this is one of the finest free flight towline gliders ever designed. Here are some photos of the Caprice, flying with the birds [more pics 018-024].

I built a third Caprice in December last year for a modelling friend who has put micro RC in it. Please find attached photos, the yellow and black one belongs to Rodney [more pics 025, 026]. Unfortunately the wind was too strong on flight day so neither model has flown off the tow line.

Under "lockdown" have just finished this 70% Caprice for Peterborough Hi-Start [more pics 027, 028]. Haven't built a glider for years but used to fly at Watton with Neville Wiilis many years ago so it was a natural choice. Hopefully we will be let out soon so I can start trimming. Pleased with a weight of 48gm so we shall see how it goes. Thanks for a fantastic site. I look every day and my "round to it" list grows ever longer. Stay safe and hopefully we'll be able to get outside fairly soon.

* 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.
