Tim Hooper Posted August 7, 2012 Author Share Posted August 7, 2012 More progress this evening. I found it convenient to lay the model on its side, and approach the interplane struts one side at a time. Brass P-clips are bolted to the wing panels and then the struts are made up from piano wire and soldered in situ. At this point the red jig can be discarded.... I shall add the wooden fairings later. Here's the underside of the upper wing with the struts detached form the lower wing and swung outwards to save space. Quote Link to comment Share on other sites More sharing options...
Concorde Speedbird Posted August 7, 2012 Share Posted August 7, 2012 Nice work Tim, interesting Jig there, I may have to conjure something like that for my Domino interplane struts. I love biplanes... and engines! Good work, she is a beauty! Can't wait to see her fly! John- Scale Concordes with 4 turbines has been done before. I will build a Concorde with EDF in the future, but only a gas turbine one if I win the lottery! Weird how I prefer engines in propellor driven planes but EDF in jets, then again I've never flown any jets, just looking at the price! Hope turbines get cheaper in the future!

Tim Hooper Posted August 19, 2012 Author Share Posted August 19, 2012 It's been a while what with one thing and another...... The rear fuselage is ringed with no less than 20 stringers. Each one has to be individually fettled and aligned to be as straight as possible. Several hours of work here! That done it seemed a good idea to add the bass wood fairings to the struts, and then pin the whole caboodle together to get some pics. Weight so far is around the 10lb mark. That doesn't include the 5 servos, 2x5S packs, covering or linkages. tim Quote Link to comment Share on other sites More sharing options...

John Olsen 1 Posted August 19, 2012 Share Posted August 19, 2012 I guess that also doesn't include any lead that might become necessary to get the CoG right either! Still, you have got your batteries well forward so with a bit of luck you might not need too much. Ten pound sounds pretty good for a model that size too. Those pictures are quite interesting, it could be almost any size to a casual glance. You need to look at the fine print on the propellor to see how big it really is.

Tim Hooper Posted August 19, 2012 Author Share Posted August 19, 2012 You're right about the lead, John! I'm sort of hoping that we won't be needing any ballast up front, but that's probably a bit of a pipe dream, isn't it? I see what you mean about the scale of the model not being apparent in the pics. I obviously need a volunteer to pose with it! tim Quote Link to comment Share on other sites More sharing options...

Vecchio Austriaco Posted August 20, 2012 Share Posted August 20, 2012 @ Tim - A few postings further up you were explaining the power train - and then there was a picture where the batteries were inside the cowl. Was this just to put them somewhere or is it planned to have them inside the cowl? means you have to charge them in the model or to take the prop off for changing them? @Concord Speedbird. You will see a Cygnet from Tims plan later that year with IC power - I already purchased the engine in a weak moment during my holiday... (was 100 Euro cheaper than on the island - so I couldnt resist importing it....). I just have to move the firewall back to get the right prop position - I think about some reinforcing of the fuselage even it will not vibrate a lot. What I need to create is a cowl. As I made some model boat hulls for my father in the past, as well as a glider fuselage (I went into serious mass production - made 5 pieces of it .....) I think it will be a fibre reinforced epoxy one. VA Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted August 20, 2012 Author Share Posted August 20, 2012 Vecchio, I'm going to have to cut an access in the top of the cowl to give access to the cells, so I can remove them for charging. Shame, but I can't think of any alternative..... CS, there's already a Cygnet with IC power being built! tim Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted August 20, 2012 Share Posted August 20, 2012 hi Tim I know you dont use them but this is where A123 come good. Timbo built a ring of cells and put them inside the cowl. you can charge in situ. We have a member that chargers his lipos in the model. not saying I agree with him but thats what he does. N28 looks fab, cant wait to see it in the flesh. Cheers Danny Quote Link to comment Share on other sites More sharing options...
John Olsen 1 Posted August 20, 2012 Share Posted August 20, 2012 Tim, How about making a hatch in the bottom of the fuselage just behind the cowl, so that you can get at the batteries through the firewall. You don't need a firewall in the same way that an IC model would, eg to keep the mess confined up front, so as long as you keep the structure sound enough to support the motor and batteries (and any of that lead stuff) you could get at the batteries by reaching up inside. Actually, looking at the pictures it might be a bit late to do that on this one, but maybe it is a thought to bear in mind for future models. The Morane actually does have a hatch underneath, it extends back about a foot so I could easily have done something like this if needed. regards John Quote Link to comment Share on other sites More sharing options...
kevin b Posted August 20, 2012 Share Posted August 20, 2012 Hi Tim. Check the originals panel lines. I'm sure they didn't make one piece cowls for full size aircraft in 1918 ! I would also suggest access from underneath as that would be a "dirtier" area from a weathering point of view, so the hatch wouldn't be as obvious.

Rene Wallage Posted August 21, 2012 Share Posted August 21, 2012 Won't you need some cooling holes in that battery box? Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted August 21, 2012 Author Share Posted August 21, 2012 So many good ideas - thanks lads! Rene, I'm planning on adding some cooling holes/slots after I work out where the UBECs, ESC and back-up battery are going live. Danny, I hear you on the A123's. It's perhaps an option for the future. I know that Gordon Tarling has recently maidened his 1/3 scale Pup, and that uses A123 cells which are left in place during charging. John, I did consider putting a hatch below and behind the cowl, but that's the mounting area for the undercarriage bearers. Kevin, I have Thomas Hamady's opus on the 28. I can't see any panel lines in any of the photos in the book. Never mind. We're t the stage of Endless Fannying About now; I cut the ailerons free this eveing and made up the servo hatches. It's all details form now on.... tim Quote Link to comment Share on other sites More sharing options...
Concorde Speedbird Posted August 21, 2012 Share Posted August 21, 2012 I'm not familiar with electric flight, I can charge a Lipo but it ends there, so can someone please clarify what an A123 is? I understand it is a battery, but what features does it have? CS Quote Link to comment Share on other sites More sharing options...
John Olsen 1 Posted August 21, 2012 Share Posted August 21, 2012 Tim, That is where my undercarriage mounts too, when the hatch is off there are a couple of stout pieces of wood across the opening. It still leaves plenty of room for access. The bits of wood the undercarriage mounts to are attached to the main plywood box structure of the front end. Most of the front end is skinned in thin ply, but the hatch is sheet balsa, which I have covered with Koverall. I did have to modify the way the hatch attaches from the design shown in the plans. It is supposed to have a single screw at the front and a couple of dowels at the back, but that means the front needs to drop down and slide forwards a little to get it off, which would be fine if there was no undercarriage or cowl to get in the way. Mine now works the opposite way to the plan, it screws on with two screws at the back and drops down there then comes back to wangle its way out of the undercarriage. With my installation this lets me get at the receiver, servos and radio battery which all live close up against the firewall.It also lets me get at the cockpit from underneath, although three servo snakes get in the way a bit there. (There are two for the elevators, each half gets its own servo.) regards John Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted September 3, 2012 Author Share Posted September 3, 2012 Thanks for the info John! Right then, despite the BMFA Nats, working overtime and all manner of domestic and social infringements, I'm glad to report that the Nieuport is almost ready to be swathed in acres of Solartex. About time too! Amongst the myriad little jobs that have been tackled, I've plumped for a set of these rigging anchors from DB Sport and Scale; **LINK** Anyone have any experience of them? tim Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted September 6, 2012 Author Share Posted September 6, 2012 Right then..... The bench is cleared and cleaned. I have 16 metres of silver, red and white Solartex. The Argos travel iron has been scrubbed. The airframe is all filled and sanded. Seems almost a shame that we're off to Old Warden tomorrow for the weekend, doesn't it? tim Quote Link to comment Share on other sites More sharing options...
Reno Racer Posted September 7, 2012 Share Posted September 7, 2012 Almost at the same stage, just lots more sanding to do and work out where to put the servos. I was shocked how much 10m of linin coloured solartex was. 16m must have felt like a second mortgage! Quote Link to comment Share on other sites More sharing options...

Concorde Speedbird Posted September 8, 2012 Share Posted September 8, 2012 Not a 28, but a 17 at Duxford today, click for full size. This one was IC, 100% scale, and it had a man strapped in it! Oh wait a second, it's a full size! Got more pics if you are interested. CS Quote Link to comment Share on other sites More sharing options...
jeff2wings Posted September 8, 2012 Share Posted September 8, 2012 Always a bit of a shame to cover up all that lovely woodwork ,it looked fantastic in those studio shots. Silver ?? going for the post WW1 U.S. or Swiss colour scheme then ?? Christian Is that a BUSA N11 or N17 Csb get on with that Galaxy Domino ,nice pics btw Quote Link to comment Share on other sites More sharing options...

Domino work will continue tomorrow now my highly enjoyable day of full size aviation is done. I love aeroplanes, and I love seeing full size in action, the sound, feeling and atmosphere is just fabulous! Back to models now though, dare I say sigh?! I do love the models though, because I can fly them! CS Quote Link to comment Share on other sites More sharing options...
Reno Racer Posted September 9, 2012 Share Posted September 9, 2012 Jeff, Its the BUSA N11. Just finished basic covering in linen solortex of tail, rudder and fuse late last night. I think, i'm using this scheme. Chris Edited By Christian Ackroyd on 09/09/2012 08:53:02 Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted September 14, 2012 Author Share Posted September 14, 2012 Looks good Chris! Well the flying surfaces are all swathed in silver Solartex. I've left the fuselage until last, as I was thinking about ways to tackle the rear fuselage. Ideally I wanted to do it all in a single pice of 'tex, so I thought I'd have a bash..... Actually, it wasn't too difficult even though the stringers are all slighlty bowed outwards! I bit of applied heat and aggression get us here.
