red Dog Posted May 26, 2017 Author Share Posted May 26, 2017 (edited) Time to address the internal support structure: The A-7 will be very low to the base, because the higher the corsair is the higher the intruder will be. And that will be a stability issue. So the intruder needs to be as low as possible. Usually I tend to use 10mm tranparent plain support rod that I insert into a 10mm hollow aluminium tube (which is 12mm in diameter) So the first step is to place that tube inside the A-7 fuselage. I hate vertical stands, IMHO they break the dynamic of the scene, but it's harder to work with oblique stands. This one will be 40° down and forward from the model (the intruder will have it down 60° something and backward The A-7 is really easy because I can mess with the lower fuselage at no risk of damaging anything because i'm inside the airbrake bay. The top fuselage is great too because I'm inside the wing. So there is zero risk of damaging anything and the two holes are providing a stable structure for the aluminium tube. The fuselages are closed and the pose is tested for being level with the horizon. The mockup base hole is not perfectly 50° but 52° so I have too much of a nose down attitude IMHO. That will be corrected on the final base. It's not very visible on the picture above but with all the resin and weight in the nose, it becomes a factor. The added bonus is that the support stand enters the lower fuselage very close to the centre of gravity of the model (with the nose resin goodies) The model is also too high on its support stand but I don't want to cut it yet. The bottom will need to be worked out further by cutting correctly the tube and fitting the closed airbrake. I planned it to be just behing the forward airbrake bulge. The top is really nice; I can adjust all I want and then by gluing the wings I will provide a stop for the support stand. Not far from an ideal situation, I struggle much more with other models. I can smell paint. Soon Edited May 26, 2017 by red Dog F`s are my favs, Starfighter, dutik and 1 other 4 Link to comment Share on other sites More sharing options...
Hawkwrench Posted May 26, 2017 Share Posted May 26, 2017 I'm not a jet guy, but this build is cool looking so far! Looking forward to more progress pics. Tim Link to comment Share on other sites More sharing options...
Eagle Driver Posted May 28, 2017 Share Posted May 28, 2017 Wicked!!! Where did you get the support parts from? DIY stuff or what? Keep 'em coming those progress pictures! We want more! Link to comment Share on other sites More sharing options...
red Dog Posted June 10, 2017 Author Share Posted June 10, 2017 (edited) I usually source the support materials in art stores. The kind of stores for the student in architecture. They have all kind of different diameter rods, hollow, plain, in acrylic or metal or plastic. I also am always on the lookout for parts that could be suitable for the inflight displays. That's the reason I have a box full of various material such as fower supports, weird design compositions, tubes etc etc. With the internal support validated, I closed the fuselage. Cokcpit and intake didn't give much trouble. It was a bit hard to get the correct placement for the cockpit sidewall as I didn't glue them on the cockpit and elected to insert them after the resin pit was sandwiched in the fuselage. The nose and intake lipe were then quickly added and adjusted One of the main fitting issue of the kit is to close the airbrake. Many builders decided to leave it slighly open to avoid the problem - which is a valid option on the ground. Unfortunately not for air to air refuel. On top of it I have the added challenge of the support rod going through the airbrake. So first thing was to drill through it at the right place and angle The fitting issue can be easily solved by adding plastic strips under the airbrake parts. By elevating them a bit the fitting is much better on top and on the side fuselage. Tha actual airbrake is a bit too long and need to be shortened at the arrows for a better fit. The inges are a potential issue and care must be taken not to sink them. To avoid it I placed some plasticard support inside. Putty was required mainly on the bump and at the end of the airbrake. The side part extending from the airbrake are sinking below the fuselage level. Once again, something that can be easily solved with bits of plastic strips palced accordingly as seen on the above. Closed airbrake. The assembly has been puttied and engraving was redone. The nose gear doors were closed shut with the usual issues. I realised too late that the launch bar is supposed to remain visible in the front opening as there is no doors for that part. I'll have to find a way to place it afterward.

dutik Posted June 10, 2017 Share Posted June 10, 2017 Nice solutions to a number of problems. Well done! I prefer to go with square supports for my inflight displays, to avoid tilting around of the model once and forever, especially if the model is intended to be removed from the base for transport. But that is a matter of taste. Most modellers are fine with round supports after the proper application of some glue.

red Dog Posted June 10, 2017 Author Share Posted June 10, 2017 (edited) I can understand that. In my case, square is not dynamic enough. It strikes me (stupidly) as non aerodynamic Go figure. That's the reason why I always exclusively use round supports. Edited June 10, 2017 by red Dog Shaka HI and dutik 2 Link to comment Share on other sites More sharing options...

dutik Posted June 10, 2017 Share Posted June 10, 2017 BTW, you are from Bruxelles... Any chance to see this display and other models here in Germany? Euro Model Expo in Lingen comes to mind, or PMC Luebeck meeting every even year. Regards - dutik Link to comment Share on other sites More sharing options...
red Dog Posted June 10, 2017 Author Share Posted June 10, 2017 got a horse trailer available ? I do a few modelshows, but mostly in Belgium as I don't travel quite far with my models. Link to comment Share on other sites More sharing options...
red Dog Posted June 11, 2017 Author Share Posted June 11, 2017 (edited) First coat of Mr Surfacer (wing assy is not glued) I'll now further work on sanding, correcting panel lines with superglue and I'll probably need to engrave a few panel lines as well. Some are very shallow Edited June 11, 2017 by red Dog blackbetty, dutik, Shawn M and 8 others 11 Link to comment Share on other sites More sharing options...

Finn Posted June 11, 2017 Share Posted June 11, 2017 Coming along very nicely, in case you want to know how dirty they got on the bottom: https://catalog.archives.gov/id/6467899 also note the chaff/flare load, just aft of the hook, 10 flare (metal) 20 chaff (blue) in each one and how they are positioned in the pods.

red Dog Posted June 12, 2017 Author Share Posted June 12, 2017 (edited) Thanks guys, Jari, I'll make good use of that picture which leads me to one particular question i kept for the future, but looking at the picture jari posted, i can see it's the same thing: does anyone know why the desert storm A-7E had most of the time asymmetrical loadouts? Most of the pictures i have seen have weapons loaded on station 1&3 (with a ter on 1) and 7&8 (with a ter on #8) Basically the TER are symmetricals (STA1 & STA8), but why are the single stations not (STA3 & STA7)? it's hard to see but the single bomb on the left wing is not on the same pylon as on the right wing. that's the exact loadout i'll use but my curiosity is aroused some more without the TERs left side right side even better, bombs have been dropped but the pylon remain: Edited June 12, 2017 by red Dog Link to comment Share on other sites More sharing options...
