  1. 1/72 DHC-4 Caribou prototype

    Hi, Ray. Thank you for your kind words. I didn't want to be tedious with the ballast operation. Well, things are as follows: 65 gr. are put in the position you see in the first pic, 55 millimeters ahead of the lift point (main gear legs) This makes a momentum of 3575 gr.x mm. putting the lead under the cockpit I gain 20 mm of arm, so 3575/75 = 47,6 grams, so 50. And this is the definitive amount. A lot anyway, but the nose is very short. Dihedral. The angle is 15°. This is the angle that the inner face of the upper wing half has to perform outboard of the nacelle, as you can see in the last pic of the unassembled wing. I had no specific evidence of the real dihedral and I eyeballed it from the images on the net. Sorry if I made some confusion, but it's not easy to explain in english. Bye Euge
  2. 1/72 DHC-4 Caribou prototype

    Hi, everybody. I feel as I have passed around Cape Horn since I found how much ballast is needed: 65gr. You can see the lead in the front of the fuselage. Some testing with cardboard to cut out the lead and fit in the nose. Ballast in position Balancing test with the ballast on place Now the dihedral problem. I made two woden spars with the correct angle to be glued inside the upper wing. The parts, of course, don't match the angle. Then I engraved along the outer wing joint, outside of the engine, always in the inner face. This allowded me to bend the part. Now on the underside i had to do the same on the external skin, where I thought to insert some plastic to bend the wing. Surprisingly there was no need to add anything and the part bent by itself. (sorry no pics) Test fit of the dihrdral with each wing glued Ok, I'm quite happy at the moment. I think I'm going to face the funny side of the build. Thank you. Regards Euge

    Thank you, Phantom, for your comment. One of the tasks of today will be balancing. I normaly put the parts together with tape and put the aircraft on two sticks where the main gear legs have to go and find the amount of weight. The real problem will be where to put it. edit: And mine has a shorter nose than your. Regards Euge
  4. CC-108 Caribou.

    Hi Phantom. I saw with pleasure your Caribou last week end at the beginning of the build and I was sure that a series aircraft would be finished before my prototype. Funny but true. Nice model. Regards Euge
  5. 1/72 DHC-4 Caribou prototype

    Hallo everybody. Thak you Ray and Dutch. Not so much to be impressed of: I made just something inside so that the fuselage does not look empty. Last wednesday and today I finished the canvas seats and prepared the nets to be put inside the windows. Still have to think at how attach them, but I'll thik it over after glueing the trasparecies. Floor painted and supports done. Test fit of the seats. Seats glued on. Test fit into the fuselage. Here is how they look like from ... inside. And here what seems to be visible from outside with the interior in the dark. Well, I got the result, didn't I? Regards Euge
  6. 1/72 DHC-4 Caribou prototype

    Thank you Ray for your comment. I've frist to say that your Cormorant came out very nice. I know the pain of red and yellow painting, and you did very well. The week end was useful to prepare some more stuff to add something inside the fuselage. I'm not going for a full interior; just what i'm afraid could be seen through the windows. The cabin floor Preparing rails for the seats Test fit of the rails into the floor Some canvas seats in test position. Hope to get back to the build next Wednesday. Thanks for watching. Euge
  7. 1/72 DHC-4 Caribou prototype

    Hi, everybody. After a long absence from modeling and from the forums I had the chance to come back to the Caribou. So I managed to almost complete all the bits for the cockpit. A thermoformed coaming, starting from a wooden master. Also added some frames inside with styrene strips and primed. Since I was at with the primer, I shot some also here And here are the parts I have to glue together: the central sliding consolle the control columns the elevator trim wheel the front gear steering wheel That's it for the week end. Thanks for wathcing. Regards Euge
  8. 1/72 DHC-4 Caribou prototype

    Hi everybody. After some holidays in Slovenia (beautiful land, BTW) I came back to the bench preparing some interiors for the Caribou. Cockpit in construction In order to put the seats rails in the correct position I started working on one of them, with the hope to make the other one as much as similar. Not great detail, but something more realistic as the parts in the kit (I hope) Thanks for watching Regards Euge
  9. 1/72 Revell DHC-6 Twin Otter 100 Aeralpi

    Thank you Ray for your comment. Some mods are required, just to improve the kit and correct the parts, other are specific for this variant. The series 100s with short nose delivered to Aeralpi were early version. (I-FALO: s/n 46) with the windows arrangement you have seen and without emergency exits and reinforcing plates on the fuselage where it meets the propeller plane. So, as always with civil aircraft, you have to look for the specific type you are going to build. Please, feel free to ask, if I can help you. Regards Euge
  10. This is the italian side of De Havilland Canada. Aeralpi was a regional airline operating in Italy in the 60s. The kit is the Revell 1/72, reboxed Matchbox plastic, with all the issues of that edition, and many signes of the time. I will build as in the following picture taken at Cremona in those years. The kit is already started, but not too much: this is where I am now. And here is how I came to this point. After correcting some kit errors, adding windows, interiors, landing lights and some rescribing, from here on it's all new. Hope you enjoy. Regards Euge
  11. 1/72 DHC-4 Caribou prototype

    Hello everybody. Spent some time for the engines replacement. New firewalls: they have to be 4 mm further back as the original, since the engines are longer. So I prepared 3 spacers to fit inside each cowling Test fit of the engine: it seems to work. Next task will be to find the proper shaft and center all parts. Thanks for watching Regards Euge

    Thank you Ray. That guy did a very nice job. He managed the dihedral issue just like I planed to do. I suspect that, after the prototype stability problem, the dhiedral of the production aircraft was rised of some degrees. See the two linked pics. link1 - prototype link2 - series aircraft Not easy to find similar views. You have to look only at the upper surface to have the right impression. Anyway, the kit parts need to be corrected in both cases. No major surgery for the engine position: I started the kit with the firm intention to keep the build simple and it already is more complicated. Regards Euge

    Thank you Ray, for your comment. I know I'm facing some surgery for the wing to correct the dihedral. The problem is in the outer section and I have a plan. As reguards the engines, I'm going to replace them since they are 18 cylinders in the kit, while they should be 14. I have some left over engines of a DC-3 that match the cowling dimensions. I'm not aware about the position of the engines you mention. I am afraid! Waiting for some suggestion from you. Regards Euge
  14. Hello everybody. This is my first entry. A very kind guy of the dhc4and5 website provided me some information about the prototype that differs from the production aircraft for few key featrures. - shorter fuselage, approx 1,1 meters - different and shorter exhaust staks - absence of fuselage strakes. Other differences will be explained during the build. First I perepared my own glue by dissolving some sprue in acetone and lacquer tinner. Then, began to study what have I to do with the exhausts, but not yet sure about. Here is where the fuselage has to be shortened. Last is the fuselage strakes removal. Some preparation to avoid damaging too much the panel lines Some sanding and restoring the panels after finishing. So, that's all for the moment. Thanks for watching. Regards Euge
  15. Whatcha gonna build?

    Hi all Canadians and Canada enthusiasts. I'm in with two builds: - De Havilland Canada DHC4 Caribou protptype. Perhaps you know I love prototypes, since I built a Chipmunk back in 2011 for the "On Canadian Wings GB" The kit is the HobbyCraft 1/72 - De Havilland Canada DHC-6 Twin Otter 100 in the Aeralpi livery. That was a little regional airline operating in northern Italy in the 60s. The kit is the Revell reboxed Matchbox 1/72. Best regards Euge
