LorenSharp Posted September 30, 2018 Author Share Posted September 30, 2018 That does put it a tad mildly Kev. I believe I created a few new "colourful metaphors" as they say at this discovery. But Overcome,Improvise and Adapt, Surrender ain't in my creed. I'm starting from the front and just work to the back and make sure it all fits right. I'm just going to ignore politely the instructions now and follow my instincts. I was wondering why they would show the individual sections done in photos gear bays etc. but not completed whole sections. And I don't think I've even seen one built at least like the B-36 and future B-52H. hmmmm. The plot coagulates me thinks.😯 1 Link to comment Share on other sites More sharing options...

"Invention is a mother.... when it's a necessity" 😉 Just remember - the instructions are only someone else's guidelines 🙂 I read them and then re-write them to suit my ideas and methods. Most of my kits in the stash have at least one A4 page of 'alternative instructions' that I've written. I look forward to seeing the plot thicken.

LorenSharp Posted September 30, 2018 Author Share Posted September 30, 2018 I like to say 'structions? We don't need no stinkin' 'structions! But i figured this time with what this beast cost I'll try to follow them. Wrong. I'll stick with my intuition, or the Force. Either is good.

LorenSharp Posted October 2, 2018 Author Share Posted October 2, 2018 (edited) Time for another exciting chapter of the Great White Beast! You know I'm gonna call the intake problem a happy accident, or a series of unfortunate events, but either way It made be step back and take a closer look at the intakes and follow my research. Case in point.to fly at Mach 3+ the intakes should be as sharp as a knife. anything less and you're just pushing a wall through the air. not very aerodynamic is it? On the left I've trimmed and sanded back to a close knife edge. On the right, as moulded. I know what you're thinking..yep this is aeronautics 101.Elementary My Dear Watson. It took looking at these images to catch what was staring at me the who time. The other portion of the front of the model has a angled dip in it all the way to the tip. This shows how far I'll have to shave and sand down the edges to get a half way decent knife edge. Now the way the model was designed I can understand from a production standpoint so it isn't damaged in transit. Just one more thing to correct. The one thing I can't correct is that the lower portion (Intake/Engine Body) has a twist and as such the lower part of the intake at the front won't be straight and level. I'll just have to correct what I can and call it a day. Edited October 2, 2018 by LorenSharp spelling 6 Link to comment Share on other sites More sharing options...

LorenSharp Posted October 2, 2018 Author Share Posted October 2, 2018 (edited) You know it's hard sometimes to remember just how BIG this plane really is. Here is a photo when it was rolled out at North American back in 1965 This the second test Vehicle or as it was designated A/V2 Biggest difference from this and A/V1 externally is the wings have a +5 degrees dihedral. lesson learned from the first one. That is a lot of rolling stock. And they built it without a computer. Just sliderules. For you youngsters, thats an early calculator,just ahead of an abacus.

That may give you the opportunity to correct some of the 'twist' and get the required air slicing look at the leading edge. Having thought of that I shall now have to dig out my Italeri XB-70 and see if that needs that extent of surgery... Kev 1 Link to comment Share on other sites More sharing options...
LorenSharp Posted October 3, 2018 Author Share Posted October 3, 2018 (edited) I had that thought when I first discovered this. The twist goes back 45%. Ideally, the entire bottom half should be replaced. To do only half way would cause a weakness at the join that would cause it to break much too easily, I don't know if I can make it strong enough and still keep the design integrity. Right now the lower portion and the wing weigh out to almost a kilo, Landing gear, tail and forward fuselage will almost double that amount. Being a fibreglass/resin composite negates using hot water or a heat gun/hairdryer to soften and retwist back. Nickolay, you are certainly correct about being heavy. had the designers gone with there original plans it would have been nearer to 375 tonnes or 750,000 lbs. made up of a bomber with 2 detachable outer wings. they were additional flying fuel tanks to be dropped near target for high speed dash. General Lemay nixed that plan because it wasn't a bomber but a 3 plane formation. Edited October 3, 2018 by LorenSharp 1 Link to comment Share on other sites More sharing options...

The only other thing that occurs to me is using some stainless steel rods to 'brace' the section, but that would not be a task for the faint-hearted. Getting the alignment right would be fraught with difficulty. I suspect your original plan of "doing what can best be done" is the prime solution.

LorenSharp Posted October 3, 2018 Author Share Posted October 3, 2018 Most would not notice the defect. I certainly didn't until I looked closely and started doing some measurements. This won't be a contest quality model by any means. Just big. If I can get it to look impressive from 2-3 feet I'll consider it a win. I'll know its there and that I can't correct it. But should any other soul be so inclined to get one of these be warned. There are pitfalls working with this type of material. 1 Link to comment Share on other sites More sharing options...

LorenSharp Posted October 3, 2018 Author Share Posted October 3, 2018 Too true NIkolay. Damn the martinis! Full speed ahead! Forward into the fog! But in all seriousness. aircraft of today are just as beautiful. The Mig-29,Su-35,our own F-22,or F-35.Heck even the F-23. They are a product of their times. Granted Those lines were created in a Computer algorithm. but that doesn't make them any less beautiful. The aircraft of tomorrow will probably be even more exotic they all will have their special place in history. Right now I'm completing a vac for a group build on another site, an XP-67 Moonbat. 1941 creation of Mcdonnell-Douglas. First instance I know of, of a "blended airfoil System" almost no straight lines on the entire plane. wing,and fuselage blended together to create an efficient low drag high speed interceptor. the most beautiful lines I've ever come across. Unfortunately it was coupled with the worst engine ever devised. An inverted aircooled low RPM 12 cylinder that caught fire if you looked at it wrong. And that happened a lot. Destroying both prototypes and killing the project. But if it had worked. who knows what aircraft of today would look like had it gone into production. 3 Link to comment Share on other sites More sharing options...

Nice to see another advocate of missed opportunities in aviation. I'm keen on some of the apparently missed chances - The Hawker P.1154 (Supersonic Harrier), The Martin Baker MB.5, The BAC TSR.2 and the various flying wings from the Hortens to the Convairs and beyond. Not so enamoured with the F-22 and F-35, but know that they are the way of the future. Excellently engineered but not really attractive. Mind you the Eurofighter Typhoon is not a pretty bird, either.

The Myasishchev M-50 never reached its performance characteristics due to lacking of power: A few weeks ago I sawed her in the museum (guess what, it’s standing there from the 1968!

Hi Nikolay I started in on the assessment of the Italeri kit, but found this thread by another forum member which covers all the difficulties I identified. So rather than repeat all his advice, here's the link to his thread - well worth a read if you wish to tackle the Italeri kit. Nothing has changed since his 2009 thread - my kit is the latest release [2014] and it's identical. The General produced a truly wonderful result from this kit, but admits that it fought him all the way. Hope this info helps you - it certainly doesn't deter me. LorenSharp - sorry if this is a bit of 'kidnap ' of your excellent thread. I shall desist and get a new thread started on the 72nd version as soon as I get to it.

LorenSharp Posted October 11, 2018 Author Share Posted October 11, 2018 The General's build is very informative and thoroughly entertaining. The final paint scheme both original and interesting. I ironically have the Amt kit in my stash as well.My original intention was to scratch build a 1/48 scale version, granted it does seem like I'm doing that now. Although I do have a Bear 95 that I want to do the same thing too as I doubt anyone would make a 1/48 version. Don't what I'll do with it now sits in storage like something out of raiders of the lost ark. 1 Link to comment Share on other sites More sharing options...

LorenSharp Posted October 15, 2018 Author Share Posted October 15, 2018 (edited) Well Time for more exciting adventures of The Great White Resin Beast, When last we saw our intrepid hero. His close inspections revealed all kinds of nasty ways resin and fibreglass can try to scupper ones build. Here at the intake opening the intake walls have been thinned and the base of the intake built up filled and smoothed. And looking at the slight twist,I may not be able to remove the twist but I may be able to create a brace to spread the intakes are at least parallel make the twist less obvious. Now the fun part is making the brace so that it blends in with the intake shafts. Kev your suggestion about the brass sheeting might be just the ticket to make that work.Thin enough to be unobtrusive and strong enough to keep everything even.
