    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Cesar,

    Here are some close ups of the full size connection. I haven't come to that part yet, so I will be interested in what everyone's solutions are. I am thinking about leaving the stick in place and connecting the loose ends of the wires to storage/transportation sticks.

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hi Cesar and others,

    this week I started, to mount the stringers on the side of the fuse, the top- and the bottom stringers

    will be glued in, after installing the servo for the rudder. Here I prefer to drive the rudder with a

    cevlar fishing line with 110 kg breaking load. The servo will be mounted on a sledge and the wires are

    mounted on an arm, to take the pulling load from the servo. By this sledge I can tense the wires evenly distributed.


    Also I had to install the tanks for gas and the smoker. I took the both notches for the reso-tunnels, because I donΒ΄t need

    them, they where a little to small and I had to make the notches a bit bigger. Now they are glued in with epoxi-resin.


    I hope, IΒ΄m not boring you all with my extended reports, may be sometime not easy to understand because

    my english is not always the best.


    Regards

    Bernie

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hi Bernie,

    The servo mount on a sledge is not a bad idea.
    When I looked at your tanks I saw fittings I have not seen before, are you sure they are leaking proof?

    I am also intended to put a smoke gear in the fuse but i have also heard that the fluid, diesel or smoke fluid give a lot of mess on your plane Γ‘nd dissolve the folie or paint on it so i am not sure yet... what is your opinion in this?

    By the way, your not boring at all, keep up the posting and the pictures.

    Cesar.

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hi Ruud,

    this fittings are from Festo, they are standard in jet-models. When you push the blue ring, you can pull out the hose.

    The filling fitting, installed under the front inspection hatch, open only when you stick in the filling hose, when pulling

    ot, itΒ΄s closed and nothing come out. I orderd the tanks here:

    http://shop.strato.de/epages/Store.s.../%20Filtern%22

    Referring to the smoke fluid, the fuse and all other parts will be painted with 2K paint, which is insensitive against most.

    I only donΒ΄t know, where to install the ventilation fitting.

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hello Bernie, your build look great!

    Since you epoxied in the tanks I was wondering if the tanks are anti-foaming. I checked the site link you have posted but do not speak German. Can you please give more details on the tanks & the install? Maybe gas does not foam as much as glow?

    Thanks for the info, Vasek

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hi Vasek,

    thatΒ΄s right, gas does not foam so much. I saw a vide froma tank with gas during the flight. There was no foam

    to see. It should show the properties during the flight, and the pilot was no sunday-flyer

    If you want 100% shure, to get no foam, install a small hoopertank.

    The tanks I installed, came ready mounted, the diameter is 93mm and the length about 200mm and the volume is 1000ml.

    Installing was very easy, I maked the surface of the tanks with sand-paper a lttle bit rawly, and than I epoxied them in.


    One question, do you built too a Waco?


    Regards

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hi guys,

    today I began to built the stab, I thought, thats easy, in a few ours it getΒ΄s ready.

    But it wasnΒ΄t so, you must be very, very careful when you epoxi in the axles of the rudder.

    ItΒ΄s very important, that all 3 axles are in on line!

    Now IΒ΄m waiting, that the epoxi drys.

    Here some pictures:

    Regards

    Bernie, thanks for the info!

    No i am not building a Waco (yet!)... i'm watching ebay for a pica 1/5.

    I really like the Barth but it's just a bit too big for me.

    Hi Vasek,

    the price for the kit of the "small" Waco YMF-5 is 752€, this is nearly 1000 USD + shiping.

    You can see here : http://www.fmbb.de/images/Preisliste2007Kunden.PDF

    Send Peter Barth an E-Mail to ask for the shipping price : FMBB-Barth@t-online.de

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hi friends,

    it was weekend, and that means building time. I hope you all had time and good weather to fly,

    and not so like me, to sit in the cellar..ha ha ha

    The fin and the rudder is now as good as ready, and I can begin with the stab and elevator.

    Today I considered a long time, to make the complete tail pretendable, because of better transportation.

    Now I come to a decision, the fin is glued in with Epoxi.......I hope, my car is big enough

    Here some photos more :

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hi Ruud,

    I decided to make it fix, it is such a lot of work, to make it pretendable.

    You must make extra connectors for the elevator servo, also the connections for the rudder and the

    tail-wheel, you have to hook up it before the flight and after. And the time you need, to make a biplane ready for

    flight is still big enough, also the flying wires of the stab...and...and...and!

    Because of these reasons, I did it fixed.

    Such a bad thing with the bad weather at your home, when the time has come for the maiden of your Waco,

    you have absolute take a videocamera and present us here a film, IΒ΄m so anxious to see it[sm=thumbup.gif][sm=thumbup.gif][sm=thumbup.gif]


    This week I took a little time, to look all your building photos, there is so much differently now, itΒ΄s easyier now

    and it goes much more quicker......only if I think about the stringers and the notches for it.

    Do yo have any photo of your Waco, now when she is ready and mounted?

    Enjoy your sunday evening

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    To make only the stab pretendable is not so much work but gives you a lot of comfort in transport. The stab have a width of 110 cm so if you must go through a door you must turn over your plane and that is not easy.

    I only have to slide the stab halfs over steel tubes, (I have changed that later in steel tubes and brass tubes inside the stab) and connect the flying wires and the elevator steering rod that's all. The servo's are mounted in the tail.

    Regards,
    Cesar

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hi Cesar and all others,

    yesterday I did cut out the finn of the rudder, Cesar has convinced me, itΒ΄s better to make the whole stab pretendable.

    ItΒ΄s a big part, the fuse with the stab, 110cm width! I would get problems in my house and in my car.

    ItΒ΄s not possible, to make only the elevator and stab pretendable, because the front tube of the stab goes now sloping in to the

    fuse, and the rear tube in a right angle! Just like the origin machine.

    So thereΒ΄s only the way, to make the whole stearing element( Rudder AND Elevator) pretendable.

    The first photo you see, is what i want to make, and the others what I did until now. But I have to consider a lot of things,

    these details are in no plan, I must create it by my self...puuuh.....what a work.

    But see self:

    Regards

    Bernie

    RE: Buiding pics Waco YMF-5 Barth Modellbau

    Hi Cesar and all others,

    here again a little report of the work of the last days. After long time of considering, how to make the stab removeable AND adjustable

    I decided me fot this solution, and would ask you four your opinion.

    The whole stab is swivel mounted, up and down. Also the servo for the elevator is mounted on this arm. The front servo you see, is for adjust

    the stab, -3Β° down and 3Β° up, if I want more or less, no problem, I only must take another hole in the sevo arm. These are not the final arms,

    they will be changed in to alu-arms. Both servos are HT 5955 TG with 24kg/330oz power.

    In the rear of the arm are two ball bearings for the drive-shaft of the elevator, I want to make the drive totally inside of the fuse, like the origin machine

    On the first photo you can see the new cunstruction of the stab, also here I have to make some modifications, the end bar will be a carbon tube

    and the outer bearings will be nearly to the origin, but hereof more later, see self:


    Regards

    Bernie
