WolstonFlyer Posted February 6, 2016 Author Share Posted February 6, 2016 Thanks guys, I am really enjoying this build so far. I only just remembered the other paper tube in time! I have just noticed a piece of balsa and the ply plate for the aileron horn that I have missed, I better do them before I forget. Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted February 6, 2016 Share Posted February 6, 2016 Re your earlier comments about the David plane, I also find it appears not to be absolutely sharp so I tend to use it an angle which seems to cut more easily. Build is coming along nicely. l think you've got the makings of a nice colour scheme lurking under the wing Quote Link to comment Share on other sites More sharing options...
AndyD Posted February 6, 2016 Share Posted February 6, 2016 not sure about a nice colour scheme John but certainly a german like feel about it. Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted February 6, 2016 Author Share Posted February 6, 2016 Thanks for the tip about cutting at an angle John, I am going to have a go a stropping the blade on my leather knife sharpening board with some buffing compound, that might put more of an edge on it. I think the heavy duty plastic tablecloth will be a bit heavy as covering material! Actually I have no idea what the colour of my model will be yet. I also need to pick some servos, I am not sure what size to go for, are the TGY-90S good enough for this model, I have 4 spare ones in stock in my parts box: **LINK** Edited By WolstonFlyer on 06/02/2016 23:16:10 Quote Link to comment Share on other sites More sharing options...
Chris Barlow Posted February 7, 2016 Share Posted February 7, 2016 That'll be fine for the ailerons in the wing but I'd recommend a standard size servo for rudder & elevator. I realise the TGY servos are rated quite high for torque but in practice they're not! Maybe they measured them at the horn screw rather than a realistic end of the horn!

Chris Barlow Posted February 7, 2016 Share Posted February 7, 2016 Try a Hitec HS325HB for durability or even a standard HS311 will do. Both cheap servos. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted February 7, 2016 Share Posted February 7, 2016 For razor planes. Go on EBay and buy the old Blue GIllette blades. Fantasic. I use Hitec HS311. If using the micro ones only ever use metal geared ones. Lost one or two flying sessions in the past just by kocking an aileron in transit. with plastic gears.

Bob Cotsford Posted February 7, 2016 Share Posted February 7, 2016 I'm using Corona DS339MGs on mine, they're metal geared and rated at 5kg.cm at 6v - BUT - the lugs are a bit brittle so they need to have the mounting screw holes drilled accurately to avoid any undue stress on the lugs. Once installed they seem ok, I've got them in a 60 size Curare where they have worked fine so far. Quote Link to comment Share on other sites More sharing options...
Craig Thomas Posted February 7, 2016 Share Posted February 7, 2016 Hi wolstonflyer. I see from your thread you made the same mistake as me with the bottom sheeting. I done the same as you and cut mine flush. I could have kicked myself once I realised what I done. But it's not the end of the world. Servo wise I've chose standard size savox sv0320. Probably slightly overrated but I figure I can always put them into my next project in years to come. Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted February 7, 2016 Author Share Posted February 7, 2016 Thanks for the Servo tips everybody, I am going to give the Corona DS339MG a go they are metal gear digital and I will get 4 of them rather than risk the micro servo's in the wing.

WolstonFlyer Posted April 13, 2016 Author Share Posted April 13, 2016 I have been building wing tips, the parts cut from the templates almost fit perfectly. Still got a bit of shaping and sanding to do and then I can fit the leading and trailing edge to the wing, then make the servo trays. Still got to start on the fuselage yet.

WolstonFlyer Posted April 14, 2016 Author Share Posted April 14, 2016 Cut the fuselage sides out, I think contact adhesive will be best to stick the plywood on to the balsa? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted April 15, 2016 Share Posted April 15, 2016 Yes. I now use a spray on contact adhesive which works well. Evostick is OK but not the water based rubbish. Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted April 15, 2016 Author Share Posted April 15, 2016 Thanks Peter, I will make sure to avoid the water based stuff and look for spray adhesive. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted April 15, 2016 Share Posted April 15, 2016 I have two that I can get from my local ironmongers. Everbuild Stick2 Instant Spray Contact adhesive And STUK Rapid spray glue. They both have adjustable nozzles and sptay a fan pattern Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted April 17, 2016 Author Share Posted April 17, 2016 I couldn't find any spray contact adhesive in the local DIY shops, so I got a small tube for a couple of pounds and it was plenty to do this job. I even remembered to make two opposite sides! I am amazed at how much extra strength the doublers give, they make a huge difference. and now I am high on glue fumes and strong coffee (don't sniff glue kids ) Edited By WolstonFlyer on 17/04/2016 14:19:09 Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted April 17, 2016 Share Posted April 17, 2016 Oh yes, Those doublers are the heart of the model r rather the lamination process is, I do all my contact adhesive work out side. Quote Link to comment Share on other sites More sharing options...
Chris Barlow Posted April 17, 2016 Share Posted April 17, 2016 Looking Good! I prefer contact adhesive for doublers simply because it does stretch a little if you need to bend the sides when building the fuselage. I used to use PVA but found it too rigid when bending the sides! Also a lot neater than when I use spray contact adhesive, I seem to get it everywhere!

WolstonFlyer Posted April 29, 2016 Author Share Posted April 29, 2016 I have started putting the formers in. Trying out my new building jig so starting with F2 and then when that has dried I will get both sides joined and in the jig then add the other formers. I am not sure how I am mounting the motor yet so F1 will be added last. Sorry about the reflection from the overhead velux window. Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted April 30, 2016 Author Share Posted April 30, 2016 A bit more progress for tonight. I am sure one of the rear formers is a bit too big and I have ended up with a hump backed Ballerina. I cut the parts to the plan (exactly) so something is off but it's too late to fix it now.

Peter Miller Posted April 30, 2016 Share Posted April 30, 2016 Yes, there was an error.on my original plan the plan vew taper started atthe trailing edge of the wing. For some reason the draftsman started it at tthe next former back. It still work but you do get the hump bacl. NOTE also that the tailplane should be glued up against F-10. Don't ask me why that was moved. Today I m checking my next plan for errors for the third time. This one should be right. Quote Link to comment Share on other sites More sharing options...
WolstonFlyer Posted April 30, 2016 Author Share Posted April 30, 2016 Ah, thank you Peter, that explains it.Thanks for the info about F10 Quote Link to comment Share on other sites More sharing options...
