Tim Hooper Posted January 25, 2013 Share Posted January 25, 2013 Martin, That's a very classy looking airframe! Lots of tricky compound curves in the fuselage and nacelles. Tiny tailplane. Mandatory retracts. Complicated glazing. Twin motors. So what's not to like? tim Quote Link to comment Share on other sites More sharing options...
Tony Bennett Posted January 25, 2013 Share Posted January 25, 2013 some times you can go off people you know. fancy finding such a nice plane. makes me want to build one. Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted January 25, 2013 Share Posted January 25, 2013 It looks like a model...... Quote Link to comment Share on other sites More sharing options...
Devcon1 Posted January 25, 2013 Share Posted January 25, 2013 Is it a scale mock up of a prototype ? Quote Link to comment Share on other sites More sharing options...
Lindsay Todd Posted January 25, 2013 Share Posted January 25, 2013 I don't no why but if you swept that wing forward, put the winglets on upside down then its not far away from a 'Clean Sweep Twin' how about that for an idea then Tim? Seriously it would make a very smart model, nothing too extreme, perhaps increase the tail surfaces areas a little to improve stability but its very do-able. (is that a word?)

Martian Posted January 25, 2013 Author Share Posted January 25, 2013 Diamond Aircraft I believe they do it as a self build really pretty tho and line drawings are available Quote Link to comment Share on other sites More sharing options...
Tim Hooper Posted January 25, 2013 Share Posted January 25, 2013 Posted by Lindsay Todd on 25/01/2013 21:45:04: ......how about that for an idea then Tim? That skinny nose would have to house the retracting noseleg AND the flight battery. The rear fuselage is even skinnier. High aspect-ratio wing would need some clever (carbon?) spars to avoid undue flexing. Two ways to go; either treat it as a powered glider, or go the opposite route and build it for speed!

twinstar Posted January 25, 2013 Share Posted January 25, 2013 or how about a ximango which is a lovely motor glider.... Tim? (the mag is well, well, overdue for a glider plan... pretty please) Edited By twinstar on 25/01/2013 23:12:02 Quote Link to comment Share on other sites More sharing options...
Lindsay Todd Posted January 25, 2013 Share Posted January 25, 2013 You see Tim, you've designed it already! I would imagine it has a rather good cruise speed, very stylish. Quote Link to comment Share on other sites More sharing options...

Martian Posted January 26, 2013 Author Share Posted January 26, 2013 It reminded me in some strange way to a Rutan Quickie ,it does look really quite different to any thing else ,front profile is very pretty so to is side profile ,the winglets make a world of difference to it's overall looks as does the downward tips on the tailplane. Original is from an Austrian manufacturer and from composite materials first flew in 2004 I think, speed is around 200mph but has been purchased as an unmanned survelliance aircraft so is able to loiter. I'm wonderin g if a model could be made in a similar way with glass fibre with electric motor at around 60" span, real plane span is 44ft wing area 175ft2 length 28ft powered by 2 Austro turbo diesels . So is it a real model prospect I'd love to have a go Quote Link to comment Share on other sites More sharing options...

Martian Posted January 29, 2013 Author Share Posted January 29, 2013 Well just when you think you have found something unique, this aircraft has been made into a model by a Chinese manufactor called FlyFly..found an Australian build blog for a fibreglass 65inch plane auw supposed to be 3.2kg but he built it to 4.1kg .it seems fibreglass is not thhe way to go it would be to heavy and to fast..Ah well at least it's keeping me busy thinking Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted January 29, 2013 Share Posted January 29, 2013 The Fly Fly Diamond DA-42 Quite a serious plane! Edited By Simon Chaddock on 29/01/2013 15:37:51 Quote Link to comment Share on other sites More sharing options...
Martian Posted January 29, 2013 Author Share Posted January 29, 2013 Yes but no price and their retail sellers in hong kong don't stock it,besides that it's all fibreglass including the wings and comes in at 7lbs ,the span at 65inch is about right but 7lbs seems quite heavy Quote Link to comment Share on other sites More sharing options...
Martian Posted January 31, 2013 Author Share Posted January 31, 2013 I've decided a model of this aircraft is do-able.looking at construction options and aerofoil sections full size wings use wortmann fx63-137 aerofoil section will check that out.likely to be balso liteply and carbon rods.canopy area detatchable for access to radio and batts Quote Link to comment Share on other sites More sharing options...
Stefan Hafner Posted January 31, 2013 Share Posted January 31, 2013 Would certainly make an interesting model, plenty of sheeting and sanding to keep any builders busy Quote Link to comment Share on other sites More sharing options...
Martian Posted February 10, 2013 Author Share Posted February 10, 2013 having read through some brilliant building and use of depron I am going to explore that option .it would certainly make a much lighter build,also looking to make fuselage out to engine nacelle ,is that a workable idea Quote Link to comment Share on other sites More sharing options...
Martian Posted April 21, 2013 Author Share Posted April 21, 2013 Well i've thought about it long enough I'm going to build it all balsa and a bit of ply,I intend to build the fuselage in 2 halves longitudely incorperating a hard balsa spine with formers then planking lots of sanding what do you think ?

Tim Hooper Posted April 22, 2013 Share Posted April 22, 2013 Looks like a winner to me. Complex, but a definite winner. Any pics yet? tim Quote Link to comment Share on other sites More sharing options...

Martian Posted May 17, 2013 Author Share Posted May 17, 2013 i was busy drawing plans when I decided to make use of a large amount of polystyrene blocks and panels that came as packaging material , I'm in the process of glueing up sections and carving out what will be the same size of model I'm drawing it will have a 40" approx fuselage 80" wingspan and a 25% tailplane the full size aircraft has 5 deg dihedral. I'm hoping this will test out the viability of a model ...will post pics when made enough progress..btw has anyone else made a model from polystyrene ?

Peter Miller Posted May 17, 2013 Share Posted May 17, 2013 We see one flying round here (Suffolk Essex border. Tailplane will be fine. I regularly use a 15% tailplane. My next scale model is down to 14% Just keep the CG at 25%. Edited By Peter Miller on 17/05/2013 18:30:33 Quote Link to comment Share on other sites More sharing options...
Martian Posted May 17, 2013 Author Share Posted May 17, 2013 thanks Peter thats the purpose to establish CG that and stability, going to look for a good hill to test glide it when it's finished Quote Link to comment Share on other sites More sharing options...
