Maybe Revell decals are not that good. I will be very cautious with mine now that I saw this. NLG bay looks fantastic and much much better than Revells. It was my fault rather than Revell decals. The decals are nicely printed, very thin but strong enough. I suspect that this happened because of Future/Pledge undercoat. Most probably it was not leveled out enough because the black paint had orange peel texture. I should have sanded the entire aircraft with 3000-4000 grit paper to have a smoother surface before applying clear coat. Being a bit impatient causes such consequences...

gordinir8 Posted June 24, 2022 Share Posted June 24, 2022 I will agree with this, revell didn't got the time to polish the mould, so the rough surface. Anyway it is still an impressive model. 1 Link to comment Share on other sites More sharing options...

Exactly this, sand the primer coat back to 2500/3000 before applying paint, then micromesh your paint back to 8000/12000 before gloss coat. It makes a big difference. 1 Link to comment Share on other sites More sharing options...
Nikolay Polyakov Posted June 25, 2022 Share Posted June 25, 2022 I’m really impressed by your progress, Serkan! 👏 The Bird looks better and better.The painted wheel wells is superb - just like the real things. 1 Link to comment Share on other sites More sharing options...
Serkan Sen Posted June 25, 2022 Author Share Posted June 25, 2022 The wheel struts and side stays have been placed. The wheels have not been painted yet but they gave been also assembled to check whether all of them are touching the ground: Legs!.. I have legs... Finally I can stand on my own feet!..

billn53 Posted June 25, 2022 Share Posted June 25, 2022 Excellent work (as always). You probably know this, but for the silvered decals you can try poking the silvered areas a few times with a needle, then coating the decal with your favorite decal softener (MicroSol, Mr Mark, SolvaSet, etc.). More than one application may be needed. 1 1 Link to comment Share on other sites More sharing options...

I should not hurried up to finish that step. No more late midnight modelling!.. 🥱😴 Serkan 1 Link to comment Share on other sites More sharing options...

Serkan Sen Posted June 30, 2022 Author Share Posted June 30, 2022 Although the wheels look not very bad I decided to model and print them as well. Because all my other ongoing Oxcart/Blackbird projects need new wheels both in 1:72 and 1:48 scales. During last couple of days I was working on nose wheel and now the model is mostly completed: I did modelling both for M-21 and SR-71A as they have different plates on the rim. You can find them here. The main wheels will be a bit challenging because of three different rims each for early and late types. Serkan 1 Link to comment Share on other sites More sharing options...
gordinir8 Posted June 30, 2022 Share Posted June 30, 2022 You may think a separate tyre and rim, this will make silver tyre painting more easy with an airbrush. I have a set of 3D printed wheels this way and it is not a bad idea. 1 Link to comment Share on other sites More sharing options...

Without printing rim halves and tyre separately it is not possible to get all tiny details on printed parts. Serkan 1 Link to comment Share on other sites More sharing options...
Serkan Sen Posted June 30, 2022 Author Share Posted June 30, 2022 While I was preparing the STL file for printing I noticed that the modelled wheel has significantly bigger diameter than the Revell one. There is a 1.6mm difference in diameter. I had to check everything again to verify the correctness of my model dimensions. I recalled the chart from Dunlop catalog to check the tyre diameter: 25 inches is equal to 13.2mm in 1:48 scale. That means the Revell nose wheel is undersized... (11.6 x 48 / 25.4 = 21.92 inches) I will do a test print soon to check the results both in 1:72 and 1:48 scales (but I have to replace first the FEP film because I damaged it while I was printing the Pokemon figures for my daughters. Normally they should have played with Barbies...) Serkan 4 Link to comment Share on other sites More sharing options...
Serkan Sen Posted June 30, 2022 Author Share Posted June 30, 2022 By the way, I was wondering if any of you have pictures of the inner side of the dismantled main wheels showing the brake details? Serkan Link to comment Share on other sites More sharing options...
Serkan Sen Posted July 3, 2022 Author Share Posted July 3, 2022 It seems that either the people hast lost their attention to this build or no one has any detailed pictures of the main wheel brakes. 🙃 I found a picture by chance here that shows the inner side of the rim with a bit detail in the comments section: https://archive.aeroscale.net/features/5059/index.htm I did some preliminary modelling and I will post the pictures soon.

gordinir8 Posted July 3, 2022 Share Posted July 3, 2022 Actually detailed photos of the SR 71 are quite rare, I was looking for the parachute bay and hardly I have found one picture with the half bay opened. This plane still keeps its secrets. Link to comment Share on other sites More sharing options...
Serkan Sen Posted July 4, 2022 Author Share Posted July 4, 2022 The basic model of main wheel tire and rim is ready. But before posting the images I noticed that the wheel looks a bit strange: very wide tire section height and very small rim diameter. BF Goodrich SR-71 tire has the dimensions 27.5x7.5-16 (cross checked from Goodyear catalogue) and what I understand that: Nominal diameter: 27.5 inches Nominal width: 7.5 inches Nominal rim diameter: 16 inches I used exactly above dimensions to model the rim and tire but definetely I miss something...

gordinir8 Posted July 4, 2022 Share Posted July 4, 2022 I think you should use real tire dimensions and then build something that looks good with your eye into the model, most possible reason is that Revell LG is not exactly as the real thing that is why when you put the exact copy of the real it looks wrong. Hypersonic models made a review on the revell kit (i am sure this guy has some very serious info on this airplane) and said that Revell wheels are wrong but maybe correct for the model. So in conclusion maybe use Revell wheels dimensions. Thomas Link to comment Share on other sites More sharing options...

Serkan ...or you could buy my wheels, readily available and with good and accurate inner detail as well I had to re-size the tyres a bit from accurate scale dimensions to make them fit the Revell main struts. A little thinner (i.e. less over all width), and slightly less tread diameter. An accurate (but again adapted for the inaccurate Revell kit) brake chute bay is available as well Jeffrey 2 1 Link to comment Share on other sites More sharing options...

Here is my first attempt of tire and rim modelling: The tire section height and rim outer flange diameter don't look correct. It doesn't fit to gear fork either. I spent a bit time to check the strut and wheel shape correctness: It seems that the fork inner surface has to be modified and my tire profile is far from the real one 🤔 Serkan 2 Link to comment Share on other sites More sharing options...

Serkan Sen Posted July 5, 2022 Author Share Posted July 5, 2022 The wheel model has been updated. The tire details are still missing but the wheel looks much better than the previous attempt: The main landing gear fork model has been updated as well. I will post the entire assembly pictures soon. Next is to add inner and outer wheel details to mid wheel model. Serkan 3 Link to comment Share on other sites More sharing options...
Serkan Sen Posted July 5, 2022 Author Share Posted July 5, 2022 Here is again the comparison of initial and final models: And the new center wheel with corrected main strut fork: And with the cloned wheels: Next step is to add inner and outer wheel details...
