72linerlover Posted November 11, 2018 Share Posted November 11, 2018 Hi ARCiers This thread is dedicated to the build of the 1/72 DHC-4 Caribou prototype CF-KTK-X. I have started this project for the "Canada 150" Group build, but some life issues have taken me away from modeling for a long time. So who is interested can visit this thread where the I describe the beginning phases. The build proceeded on and off during this last year with little progress. Next job was to modify the exhausts that were different in the prototype I'll cut the tubes at the right time, just before glueing. Meanwhile the office is almost finished. I spent a few time rescribing the nose, as the original is pure phantasy That's it, for the moment. Comments welcome. Regards Euge Quote Link to post Share on other sites
72linerlover Posted November 14, 2018 Author Share Posted November 14, 2018 (edited) Hi everybody. First of all I need to say thank you to "Dutch" for the appreciation on the original thread. More an empiric than scientific method, but usually it works. On to interiors. I already prepared the mesh to put along the inside of the fuselage, but... I found a short video of the presentation aircraft and it is clearly visible that there was no mesh inside. It is a short fuselage Caribou, so it is the prototype. There is only some framing that I tried to make. Painted and glued iside So also the windows are glued and secured wit a styrene plate to cover the transparencies between them. That's all for tonight. Thanks for watching Euge Edited April 20, 2019 by 72linerlover updated vide link Quote Link to post Share on other sites
72linerlover Posted December 2, 2018 Author Share Posted December 2, 2018 Hi everybody. As I said in the original thread, the engine included in the kit are wrong, so I decided to use those from a DC-3 Some modifications in the cowling are necessary to position the new engines. More than that, the real problem was to center the parts each other. A jig is necessary. This has to go in front of the cowling. With both cylinders rows glued together and painited and a sort of firewall, this is the result. Thanks for watching Best regards Euge Quote Link to post Share on other sites

72linerlover Posted January 6, 2019 Author Share Posted January 6, 2019 Hi, everybody and happy new year. It's time now to give some atention to the tail end of the fuselage. The kit parts are quite acceptable, but to bring some more life to this section I decided to separate the control surfaces of the tailplanes. This means that I had to close some gaps that the operation geneated. I did it with some cyanoacrylate and talcum powder, one of my preferred filler. To be sure to keep at minimum the further sanding, I put underneath a steel plate covered by scotch tape, as release agent. This is the vertical fin, and the same process was applied to the horizontal planes. The tailplanes of the real thing are mounted on shaft and there is a plate moving with them, I suppose. So I sanded the fairings, made a hole and the plate I mentioned before. Perhaps not perfect, but it gives an idea. Thanks for watching. All comments welcome.

72linerlover Posted May 11, 2019 Author Share Posted May 11, 2019 Hi, everybody. Time for an update. The fuselage halves are glued together, except the nose section. Here the fuselage upside down with the last part of the nose ballast. A test fit of the nose: it will require some adjusting. Meanwhile the glazing is framed inside and seems to fit OK with the front end... we will see. That's all, folks. Thanks for watching Euge Quote Link to post Share on other sites
Trojan Thunder Posted May 14, 2019 Share Posted May 14, 2019 Nice to see more progress Euge, did you sue a black marker to do the inside of the windsrceen framing? Quote Link to post Share on other sites
72linerlover Posted May 14, 2019 Author Share Posted May 14, 2019 Quote Nice to see more progress Euge, did you sue a black marker to do the inside of the windsrceen framing? Hi Ray. The internal framing are made of black vinyl electrical tape. I cut it in stripes, lay them on a flat glass, light sanded to tone down the glossy finish, and applied to the glazing. (I made this way the first time 20 years ago, I still have the model and the tape is still there, so I'm confident it will last) Bye Euge Quote Link to post Share on other sites
72linerlover Posted May 20, 2019 Author Share Posted May 20, 2019 Hi everyone. Got some free time this afternoon, so I can report about the last activity. As you can see from this manual page, the retracting kinematic is really complicated. It has nothing to do with what is in the kit. Another point is that the prototype had a three part gear doors and not two parts as in the series aircraft. There also are photos in which the doors are not visible, maybe sometimes because they weren't there or were closed (the front ones, at least). So I started adding some structure inside the gear wells. After that, I prepared the rear door and the parts to complete the nacelles underside. In the series aircraft are not present, since substituted by the long two doors. (difficult to explain, but I hope you get the point) Here the parts and here in place Here a test fit of all the elements. The rear door still has to be cut to size.

Trojan Thunder Posted May 21, 2019 Share Posted May 21, 2019 Nice details work there Euge, interesting how over simplified the kit producers can make things. Quote Link to post Share on other sites
Dutch Posted May 21, 2019 Share Posted May 21, 2019 Euge, Yes indeed! That is an incredible amount of detail and "accurizing" (if that is a word) that you are putting into this build. The results are beautiful. Thanks for sharing with us. I like you thought process and techniques. Keep up the great work. Kindest regards, Dutch Quote Link to post Share on other sites

Yes that's the reason because the aftermarket producers are for. Unfortunately I don't feel comfortable with those tiny bits of brass. On 5/21/2019 at 2:26 PM, Dutch said: accurizing Duch, that I don't know too, but it is cool. This gives me the chance to ask to be corrected, since I know, I make lots of mistakes in English.

72linerlover Posted June 16, 2019 Author Share Posted June 16, 2019 (edited) Hi mates. More done than posted in the past weeks. Thank you Nikolaos for your appreciation. Back to the manual. The two trim tabs that protrude after the trailing edge are a bit coarse. So I cut them off and redone with some styrene. Following modification is valid also for the series aircraft and it is due to a minor error of the kit. As you can see from the manual, the actuator and linkage of the outer aileron-flap (n.29) are aligned with the end of the trim tab (the newly done one). Unfortunately the fixing hole in the kit wing is in the wrong position. So I drilled a new one and closed the old one with some melted stretched sprue. Et voilà, sanded and polished. Another note: the little trim tab (n.30) is present only on the right wing. So it is better to deepen the engraved line to make it different from the left one. Actually also the glazing is glued to the fuselage with 2 component clear epoxy and it is setting. Pics in the next days. That's all for the moment. Thanks for watching. Regards Euge.

72linerlover Posted June 25, 2019 Author Share Posted June 25, 2019 Hallo. I'm a bit late for the pics I promised. Sometime when you check something you have done, it seems OK, but when you take pics for the forum, well, it's not. I have a lot of cleaning and adjusting with the glazing. Nothing impossible but I have to be careful. Something better with the tailplane hinges. Also the fin is taking shape. I hope to get some wings and fuselage together next time. Not soon, since the next week end I'll be in Zeltweg for the F1 Gran Prix. Thanks for watching. Regards Euge Quote Link to post Share on other sites

72linerlover Posted August 5, 2019 Author Share Posted August 5, 2019 Thank you, HAJO and Ray. So, something new. I thought it was an easy task to glue the wings to the fuselage, but it didn't. Probably due to my mistake when I forced the parts for the new dihedral, I missed the planarity of the root rib and the wings look down. So now I need to sand it till I get again the correct dihedral. But, what to do to be sure that the future landing gears legs will be vertical? I inserted two iron rods in the hole for said legs and I sanded till I can estimate them vertical. The right wing is almost done The left one is still to do. It has been a time consuming task to get a decent wing - fuselage fit. Also, the joint was very loose, so I added some plastic to the insert plates to get them more rigid. This is the result. I used epoxy glue to have a secure joint: I should have thought before and prepare some pins, but I didn't and at this time it would have been dangerous to drill anything in the fuselage, running the risk to have plastic powder floating inside the fuselage. Static electricity would have attracted them (sure) onto the windows. Don't ask how I know. Then I secured the joints, filling the unavoidable gaps with some superglue. Quite difficult to tell in the following pics, but it is there and sanded. Now it seems that the dihedral is almost close to the real thing, or I hope so. Now it's time to give her a bath and a good shot of primer, just to understand where I am. Thanks for following. Euge Quote Link to post Share on other sites
Trojan Thunder Posted August 5, 2019 Share Posted August 5, 2019 Good to see you sorted the dihedral. Nice work Quote Link to post Share on other sites
Dutch Posted August 15, 2019 Share Posted August 15, 2019 Euge, I have been out for a few weeks and just came back to check in. WOW! You have progressed along beautifully. I am enjoying watching your methods and techniques in adding detail. I hope to have more time in the future to be able to do the same to some of my favorite large transport kits. Thank you for sharing your work. R/ Dutch Quote Link to post Share on other sites
Loach Driver Posted August 18, 2019 Share Posted August 18, 2019 Great work on this DHC. It's one of those left-field aircraft that has always been of interest. LD. Quote Link to post Share on other sites
72linerlover Posted September 1, 2019 Author Share Posted September 1, 2019 (edited) Hi, guys, thank you for your kind comments. I know I am late in responding, but first I've been on vacation for a week on the Adriatic sea and than had some modeling problems. Well not really a problem, but a mistake. I totally forgot that the proptotype had no de-icing boots on the leading edge as the series aircraft have. For that, Hobbycraft provided some finely engraved lines to help the modeler masking and painting black. This fact delayed the priming stage. So I had to protect the surrounding area, lay down Tamiya white putty, and sand flush. While I was polishing the wing, the model slipped down from its jig, hit the workbench hard and partially cracked the nose end where glued. No reports on words in the air of that evening. And no pics too. Annoying task to repair, but now it's done. That's all. Thanks for following. Regards Euge Edited October 31, 2019 by 72linerlover Quote Link to post Share on other sites
Trojan Thunder Posted September 1, 2019 Share Posted September 1, 2019 Hope you enjoyed you holiday Euge, all these small details will make it a very unique build. Well I can confess I have not seen anyone attempt to backdate the kit to the prototype before you! Quote Link to post Share on other sites
