Hi to all footy international tribe.
At the end of a long work started in autumn 2012 with my friend Camillo, now the complete set of drawing and the construction description of Easy Footy is shared by texts and photo sequences that you’d see and free download from the new internet site www.footy-italia.it.
This is the link of dedicated pages: http://www.footy-italia.it/progetti-footy/easy-footy/
There you’ll see one first page with all the downloadable files, a general description and the links at the 11 chapter dedicated to every part of the boat, rig and sail construction and assembly.
Of course at the moment the texts are only in Italian but are in simple short phrases and with google translator you’d understand quite everything.
The photo sequences instead are good in all languages.
Now that is a realy great idea… wow… keep me updated on the progress with the kids… I never even though of using depron… how are you going to make the hull strong and waterproof???I dont think you can use resin…
what about packing tape and then resin the hull… the tape would protect the depron . would it not?..
also you got me interested… could you use your idea to make a flying JIB. and not a swing rig?
Hi Cougar,
just a short answer because for me is very late (quite1:00 AM)
Depron is very light and, used in the correct way with a design that cope with the material could be also very strong. So every time were needed are present internal reinforcements and “shear panels” that distribute the charges on the structure.
For avoid bearing effort on depron, all the tubes that pass the depron, pass also through a poliester foil bonded to the depron with UHU Por
To avoid problems in handling and holes in the hull, all the hull si covered by a PVC plastic adesive film.
If you whant to utilize epoxi resin, polistirene/depron cope very well with epoxi without any problems… but, no epoxi resin are needed for this boat, are no necessary.
For the sealing of the hull is used, after bonding parts with UHU Por, a PU glue that is a monocomponent poliuretanic resin that expand and become a foam during polimerization and seal completely (like a true filler) all the junctions of the hull. See dedicated chapter http://www.footy-italia.it/progetti-footy/easy-footy/montaggio-timone-e-deriva/ and image
In the monocompont PU glue, the “catalization” happens due to the contact with atmosferic moinsture.
This kind of sealant is very light and allow good tolerances in hull assembly: this winter I performed modelism courses in schools near Turin and 7 young modelers (11-14 age) creates starting from raw materials their own little footy and this summer they start sailing with them… you could understand that the precision in realization is not so much;)… but with this system all the boats are perfectely sealed:D
Actually only in italian… but photos speak all languages and google translator help well because, were possible,all texts are written in short and simply phrases in order to allow a simple translation:D
I also prepared the instructions (on demand according to the needing) for making little series of 5-8 short kits for other teachers/schools if they’ll want making similar courses.
Bye
First of all, thank you very much for easy III !! great plan and great work explaining it
I have one Easy III in progress (for me) and one to come ( Iwant my nine years old daughter to builf one ber herself, which seems possible according to what you did publish)
thank you very much for your appreciation, the great family of Easy Footy III grows every day not only on Italy.
About the interchangeability between Easy rig and UNA Rig from AlpYachts at the moment I’m not able to answer your question, could be that the angles of rotating pivot and center of effort on sailing surface are a little bit differents: i’ll have to make any verification about it before answer you.
By sure, the maximum rig A+ of UNA Rig from AlpYachts(appros less than 14 dm2) is very little compared to the A+ rig for Easy Footy that is more than 20 dm2.
I suppose that this big difference is due to the 2 different displacemente of Easy Footy and the AlpYachts boat: I suppose that Easy Footy is heavier.
In next days I’ll verify the geometrical main differences between the 2 kinds of rigs in order to answer you clearly about the interchangeability.
Bye
In the last nights… I’ve performed the check for the differences between the sail center of effort on Unarig fron Alp-yachts and Easy Rig: the center of sailing effort are quite the same on both; could be that the Alp-yacht is any millimeter behind but not so much.
I suggest, in any case that could be better to add one pivot hole forward 7-8 mm
Now I’m trying toi perform any test with different geometry for Unarig more similar to the last one used from Phil Tyler in the last Gold Cup.
The shape of sails will be more triangular in order to obtain a lower center of effort on sail that could allow a better balancing on the boat.
Also will be used, for the biggest rigs, a simplified rotating “sprit” in order to quite avoid battens in the head of sail.
This solution is utilized on the Genova’s footy of Federico Steri and Gigi Audizio and it is a mix of the solution of Urca Footy rig and Stollery rig.
This is the first experiment
New sails will be more “triagular”
I next weeks, the Guys of Venaria Modelism Schools will realize with me the first ones new rigs and so I’ll post any detailed images about this solution.
It’s good to see that Footy building and sailing still has a big interest, and with the younger people, especially since the RG65 class seems to be so popular too. We had some Footies in my area, but they all disappeared so people can sail the bigger, faster models. :rolleyes: And those were from sailors who “like to race”
I’m trying to do some course of modeling, but young people are still few and they are all at the beginning. their presence in the races very dependent on their parents and by the time committed to make them navigate … which is very limited.
At the end of those that race are not so many.
I think the footy are very stimulating for all those modelers who always have designed and built their boats because with little expense can achieve competitive means both in relation to their ability to project both manual.
For our group in Turin area, the footy are a great solution because proper fitting sails very large, allow us to have fun even in lakes with no wind.
We all love racing and competing with the footy and with simplified rules allows you to play without many problems and a few occasionally little push is not a problem …
Of course, for us, footy sailing is also racing!
And the fact that they are small does not mean that they are easier to make racing … quite the opposite.
bye

You are quite correct. When I show friends how to sail the Footy, I will say, “I will close my eyes for 2 seconds” and I will do that. and after that time, the Footy is totally 180 degrees turned around! And in heavy wind, you need even more attention.
While watching the AC racing in San Fransisco, the TV people said many times that part of the reason for the AC72 class is to get the interest of the younger people, so they grow up dreaming of sailing 45 knots (70+ KPH) and to get them sailing for the experience to be future champions.
It happens because you are not sailing an Urca Footy…
I’m joking… :)
Anyway in the project of my boat I made a great effort to obtain a non-common stability for a footy without losing the possibility of have quick turning and, also in in windy and wavy condition Urca Footy, with the right sail set up, it’s very stable an you could live your RC transmitter on the ground while the boat is continuing straight sailing upwind.
But Urca Footy utilize also a main sail + gib rig… .On the Easy Footy till now I’ve never reached a similar balancing that allow the boat sailing alone for long periods.
This characteristic on Urca footy is a good thing, but there are other problems: in any case it is necessary a big attention to obtain the best performance (like with other footy); in the same time, more stability means also that different sails set up could give a good balancing, but not all the “balanced” set ups give the best speed and so it is a little more difficult to find the best one for Urca Footy compared to Easy Footy.
I think that it happens due to the short distance between fin and rudder (On Urca footy it is quite the double compared to Easy Footy) but I think that it also is due to the Una rig that it’s normally less stable and more difficult to be well balanced.
I’ve not so big experience about Una Rig compared to a normal rig and so, especially for me, find a good balancing and the best performance on easy footy it’s very difficult.
For my point of view, AC72 are fantastic for the technology used and the extraordinary speed performance.
The spectacular sailing of similar flying boat it’s not comparable with the old ones… the costs are high, but in the same time for an old IACC5 a lot and billions of dollars are to be spent to gain 0,1 knots…
In Americas Cup boats are like holes in the water: as many million you’ll have available… as many you’ll put inside.
Could be that younger people grow up dreaming of sailing 45 knots… I also sailed any times on a foiling Moth and I was completely enthusiastic about it…If anyone want speed there are also windsurf and Kites that give more speed in more simple way.
In our Footy group there are people coming from different sailing experience, any one has been a “big champion” in other “full scale” class… but we amuse us also with footy, the littlest and slowest existing boat.
But I think that true sailing “passion” would not depend from the speed and dimension of the boats… and for sailing sometims could be better the passion than the enthusiasm.
[QUOTE = TomoHawk; 69482] the Urca Footy is a beautiful boat. I would be interested in the Urca hull or kit, but I do not have the skill to make the foam hulls …
How is it That they connect the servo extension rod to the rudder tiller? It looks like a piece of flexible tube is used? [/QUOTE]
About Urca Footy V2, do not even exist real drawings because it was made by hand and “eye” adding pieces to a master foam of V1 … there are a total of 4 V2units of which 3 are made from a two-piece mold in plaster to give boats at the best level to my friends of Turin and to me a reserve hull. I’m very busy with my work and hobbies and the kids and I have no time to produce boats for others.
For the new V3 I think I’ll make a mold and then build some more over to my hull, but it is still much to be done … I do not know if and when.

I like the use of the heat shrink tubing. I also like the wire piece used for the arm of the sail servo. However, I prefer to use the industrial heat gun instead of the cigarette lighter. If used arefully, a hair dryer will work too, but slower.
I use the Google Translate addon for FireFox to translate the Footy-Italia pages. It works very well, but the printing is not working yet.
I’m impressed in your Record-setting accomplishment to sail a model boat 85 miles! across the open ocean to Corsica :zbeer::captain:Not only was it a great accomplishment for model sailing, but navigating the escort boat.
Hello Claudio could you please put detail on the carbon film you use for decoration ?
I guess it is 2D Carbon film ?
Isnt it heavy ?
Where to find some i find only 3D Carbon films ?
Depron surface is dirty after building so … it does not look that nice, I was thinkingspraying plastic dip over it ! ?

Hi Chewbee,
I suggest you not try to paint depron. The paint don’t add any strenght to the depron and it is only weight added.
Adhesive PVC create a smoot and hart surface that protect the boat from holes and dents giving a beautiful look with quite nothing to work.
I utilized on my Footy an adhesive vinyl for car: there are a lot of colours and also various kind carbon look.
The type carbon look 3D is not shiny and it is just heavier than normal.
The weight of the adhesive coating is estimated at less than 20 grams for a hull that weights 18 grams. The finished weight of the hull is less than 40 grams … my ultralight Urca Footy in fiberglass weights 40 grams to be painted and about 50 grams painted.
In italy you could find Adhesive Vinyl (defined also “Vinyl for plotter” in graphics shop, insignia for shop windows, printing centers, Automotive (car and Mortor bike) decoration.
I think, if you’ll not find near home that the most simple solution is to try with google / ebay in your country and see what is near or buy online.
After having asked all those questions, it is time to share
My easy III is now finished (has not sailed yet)
I have asked Claudio about fitting an AlpYachts UNA Rig, and this s what I did (therefore the three mast holes)
Otherwise it is pretty much a vanilla Easy III
the lead bulb is a 300 (really 284 gr) fishing lead that I dig and hammered (i could probably cover him with mastic to get a decent look)
So
)
