Chris Barlow Posted January 24, 2017 Share Posted January 24, 2017 John,Can you tell me how much you wing ribs and spars weigh for one wing please? Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 24, 2017 Author Share Posted January 24, 2017 One half of top wing, lower wing is shorter and spars have been left a bit over length till built up. John says 42 by the way Edited By john stones 1 on 24/01/2017 13:36:14 Quote Link to comment Share on other sites More sharing options...
Chris Barlow Posted January 24, 2017 Share Posted January 24, 2017 Thanks John.Just wanted to know the difference between a built up wing and a foam core wing. I need practice with the hot wire cutter before I attempt the Dragon Lady after this and a Bronco. Quote Link to comment Share on other sites More sharing options...

john stones 1 - Moderator Posted January 24, 2017 Author Share Posted January 24, 2017 Glue the 1/4 l/e to lower sheeting and rear spar to its lower sheeting, easier to handle it all this way for me, pva on all joints...wait to dry then build wing.

john stones 1 - Moderator Posted January 24, 2017 Author Share Posted January 24, 2017 Bit done now kids are in bed (Iqon n Gary) Ribs glued in place, will be inset ailerons and ribs go all the way back to t/e as you can see, leave it overnight till i do any more.

McG 6969 Posted January 25, 2017 Share Posted January 25, 2017 Quite a large can of 'spinach' back into your arms now, John. Very nice progress there. Cheers Chris Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 25, 2017 Author Share Posted January 25, 2017 Inset ailerons on mine, do i go 4 bays wide or 5 ? panel itself is 9 bays + tips. Don't be shy replying if you've an opinion John Quote Link to comment Share on other sites More sharing options...
McG 6969 Posted January 25, 2017 Share Posted January 25, 2017 Well, I'm rather shy, John. But, I'll try to do my best. A 'classical' rule for inset ailerons seems to be: - 1/4 of the wingspan. - positioned as close as possible to the wingtip. - with a depth of 1/4 of the chord if it is a constant chord wing. Is that of any help to you? Cheers Chris Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 25, 2017 Author Share Posted January 25, 2017 Your best is good enough for me Chris, i have pretty close to those numbers, so thanks for the help Bit drying on lower wing but not worth a picy yet. Changed plan to servos in lower wing only, its a pain routing wires from top wing. John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 25, 2017 Author Share Posted January 25, 2017 Lower panel laid and glued up, bit of a bonus, you get both halves for left and right panels out of a 2 x36" sheet/spar John Quote Link to comment Share on other sites More sharing options...
Nev Posted January 25, 2017 Share Posted January 25, 2017 Ahh some gluing at last. Are you planning ailerons on top and bottom wings, if so then maybe 4 bays would be enough but having never built a biplane I'm only guessing. Nev. Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 25, 2017 Author Share Posted January 25, 2017 Hello Nev Ailerons top n bottom, i forgot lower wing is shorter span, so 4 bays it is...i think John Quote Link to comment Share on other sites More sharing options...
Lucas Hofman Posted January 26, 2017 Share Posted January 26, 2017 4 bays should do I think (with 1/4 cord). That is just under half the span (excluding tips), and should give ample roll rate. Lucas Quote Link to comment Share on other sites More sharing options...
Mark Elen Posted January 26, 2017 Share Posted January 26, 2017 Hi John, Many thanks for your generous comments over on my Ballerina build blog. I'm watching this with lots of interest. Very nice wing building going on here. Regards Mark Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted January 26, 2017 Author Share Posted January 26, 2017 Thanks fellas I had a picture in my head this model was bigger, it'll fit in car fully rigged and being lecky it'll store at home with no fuss, growing on me the more i look at it comparison of upper lower wingspan.

john stones 1 - Moderator Posted January 26, 2017 Author Share Posted January 26, 2017 Here's how i make fuzz sides, trace out, then pin to balsa and cut out using a straight edge, or you can go over again with a pen and leave an imprint.

Lucas Hofman Posted January 27, 2017 Share Posted January 27, 2017 You are going awfully fast John. Nice to see you are using the "Peter Miller" way of building the way, as opposed to Lindsay, who put all sheeting on after the wings were joined and removed from the board.

john stones 1 - Moderator Posted January 27, 2017 Author Share Posted January 27, 2017 Flat bottomed so no fiddling with it. Fuzz sides done, feels like a light build so far John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted February 2, 2017 Author Share Posted February 2, 2017 Started the left hand wing panels but nothing worth showing yet, altered fin construction a little, 2 x 1/4 square for l/e, i think it comes out stronger that way ? t/e strip is narrower coz it'll have 1/8 strips inside to add strength on the cross spars. John Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted February 3, 2017 Author Share Posted February 3, 2017 Lower left panel started, and fin glued up, i've added infils between cross pieces 1/8 at rear and 1/16 at front, locks it all up nicely and will be same diameter once sanded up.
