Edwin van der Maat Posted September 27, 2012 Author Share Posted September 27, 2012 Goodevening, yesterday afternoon and evening, I sheeted the fuselage: The straight fuselage sides. The nose deck. The cockpit cut-out. The start of the rear top deck. Extra support between the formers. The rear top dexk closed. Well, time to do some work on the sheeting around the stab and fin.

Ton van Munsteren Posted September 27, 2012 Share Posted September 27, 2012 Edwin, Great build and very quick as always. Like that dashboard much better than the original design, that was the reason I altered that on the free plan. Do hope you go the extra mile on the cockpit. Keep posting those pics.

Edwin van der Maat Posted September 27, 2012 Author Share Posted September 27, 2012 Hi Ton, Thanks. Of course there will a detailed cockpit. I will need the assisstance of my wife to create a pilot. The 1:4 size does not fit properly, and since the model is 1:4.3, I think I will use a 1:5 scale bust as the bases for a 'full' pilot (by the looks of it will the poor guy no feet and maybe shorter legs). Continued the build. First I tackled the wing to fuselage bottom at the wing leading edge. On the photos of the original the fairing is clearly visible. Used a ply template temporary at the landing position to get the height right. Made up a small support frame of scrap 3mm balsa. After 3 attempts , I finally got a reasonable fairing. The first one, I moved the sheeting of 1.5mm when I was gluing and got stuck. The second one was good, but the fairing was too round. So remove again . Flatten the side of the frame, and this time glued the 1.5mm sheet with woodglue. I used a bit of balsa light filler on the afted.Tomorrow, I can sand the area smooth. The second part today was to sort out the tail area. Measured out the stab agains the wing. No adjustment to the tail cut out were required. So the tail surfaces were glued in place. Prepared a template for the 2mm sheeting around the fin to stab. The sheeting was cut, sprayed water on the outside to make the balsa more flexible and glued the pieces in place. Then I added the dorsal fin. I used a bit of balsa light filler around the edges. Tomorrow, I can sand the areas smooth and round of the dorsal fin area at the fin. That was it for today.

Edwin van der Maat Posted September 29, 2012 Author Share Posted September 29, 2012 Goodmorning, Last night sanded the areas around the fin and stab smooth. Then concentrated on the aileron balance horns. Marked out the horn with reference to the 3-view. Cut off the horn and trimmed the edge back to follow the rib. Added some scrap 3mm balsa and sanded smooth with the wing. After glued in a filler piece of 3mm balsa in the shape of a triangle to close the aft end of the tip. Then I trimmed the horn to have approx. 1.5mm clearance all around, and pinned the horn in the correct position with the aileron in place. The aileron is held neutral by use of the small balsa tool I made before. I cut and glued in filler pieces to attach the horn to the aileron. So both horns are ready. The only part left of the basic build of the wing is to strengthen the wing bolt hole area, and a bit of sanding. Edwin Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted September 29, 2012 Author Share Posted September 29, 2012 The next part is more challenging because here I have to deviate from the plan quite a bit. The first part is to glue the nose ring from the kit. Since I only have the rear mount for the motor, I need to install a engine mount and cut out the first former. With the dremel I made a round hole matching the inner diameter of the nose ring. Later I will smoothen this, when I finish the nose shape. On drawing (RBC) is shows a cooling hole on either side. With the hot climate here, some extra cooling air is always good. The nose bottom hatch front former is of a different shape than the model of the original one I am building. **LINK** So I started with 3mm balsa base glued to the kit F3 former. Then I made some new pieces to create an intake. After that I made a balsa template for the cowling shape. Sine I did not know how much I had to modify the nose shape, I glued in some extra wood. Later I will shape this to have more access room. Using the template I cut 2cm light balsa pieces and glued them together. After a bit of sanding, I achieved a reasonable shape. After lunch the other side and given everything a good sanding, before proceeding with motor mount. For the cooling holes, I made some balsa fairings to guide the ram air onto the motor. These will be inside the provided vacuum formed engine cowling cheeks. Best regards, Edwin Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted September 29, 2012 Author Share Posted September 29, 2012 Goodevening, Finished the hatch. The nose ring required a little filler on both fuselage side, which still needs to sanded. The hatch in place. The motor installation. The spinner I have is about 4mm to big in diameter, but that is not a problem to continue for the moment. Later I will purchase the correct size. Made a guide to mark the new firewall location. Added a light ply filler plate on each side of the fuselage. The firewall was initial made from lightply to get a good fit, and then on each side proper 2mm ply was glued on. The firewall is glued in place with 5mm epoxy. Temporary put the motor in place. The status of the project so far: Next steps: 1. build the wingroot fairings. 2. install the elevator and rudder servos. 3. prepare the control run for the elevator and rudder. 4. prepare the landing gear.

Edwin van der Maat Posted September 30, 2012 Author Share Posted September 30, 2012 Goodevening, managed to work a couple of hours today on the wingroot fairings. It was very windy today, so I skipped the flying. The fairing is build up of a bottom / top piece of 0.4mm ply, some 3mm balsa formers and some pieces cut from light balsa triangle.

Ton van Munsteren Posted September 30, 2012 Share Posted September 30, 2012 Edwin, Good fun to see that you give the Corby kit a good twist. Like the modification you have done so far. Ton Quote Link to comment Share on other sites More sharing options...
bouncebounce crunch Posted October 1, 2012 Share Posted October 1, 2012 This is lookin good I have been interested in Ton's, Starlet too and the scale details he added, so I am rubbing my hands together with this one. Good job. Edited By bouncebouncecrunch on 01/10/2012 09:29:12 Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted October 1, 2012 Author Share Posted October 1, 2012 Dear bouncebouncecrunch, Thanks for the reply. You should build one. Hi Ton, . Thanks. Best regards, Edwin Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted October 17, 2012 Author Share Posted October 17, 2012 Good afternoon, After more than two busy weeks, finally an update on the Corby project. During the last days managed to work some time on the wing and control surface covering and progressed a bit on the fuselage. First the preparation of the stitches on a piece of solartex. Simple sewed on to the material using a sewing machine. Then lightly covered with balsaloc on the 'none-glue side'. After the balsaloc is dry, strips of approx. 3mm width are cut. The control surface covering in progress. The entire wing is covered in solartex. The stitches applied with the iron. Then a rib tape of 10 mm width solartex ironed over it. It is a bit difficult to see due to the antik solartex colour. Best regards, Edwin Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted October 21, 2012 Author Share Posted October 21, 2012 Goodevening, completed the stitches and tapes on the wing, ailerons, elevators and rudder. The wing covering completed. The ailerons are temporary fitted (not glued) for the picture. I started on the detailing of the bottom of the wing center section panels. There is not much more on the original aircraft wing except the pitot head, tie down rings and the aileron drive fairings.

Ton van Munsteren Posted October 21, 2012 Share Posted October 21, 2012 Edwin, That looks great, well done, so much fun doing this detail work don't you think. Ton Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 21, 2012 Share Posted October 21, 2012 NIcely done Edwin, I have seen rib tapes done lots of ways but stitiching across the solartex like that is a new method to me, looks to have worked well Cheers Danny Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted October 22, 2012 Author Share Posted October 22, 2012 Hi Ton, For sure. It is nice to research the model and make a decision on how much detail to add and to what level. The original Corby does not have much surface detail, so it a nice project as a step in to build and fly scale models. Hi Danny, Thanks for the feedback. I use different methods from real stitching to using rib stitch (double sided tape with stitches) to this method. I find that using this method works good on 1/6 to 1/4 scale models. But always on the look out for new methods. Every scale project is a new learning curve. Best regards, Edwin Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted October 27, 2012 Author Share Posted October 27, 2012 Good evening, made some progress on the Corby. The fuselage is covered and painted in white. I used solartex, then I gave it two coats of dope. Added the cheeks and used a bit of filler to make a smooth fairing as per the original and as well on the solartex overlapping edges. Some coats of primer which where sanded back as far as possible. Photos will follow because I forgot to upload them. Edwin Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted October 27, 2012 Author Share Posted October 27, 2012 Hereby the pictures: At least now I can start with the cockpit.... Best regards, Edwin Quote Link to comment Share on other sites More sharing options...
Danny Fenton Posted October 27, 2012 Share Posted October 27, 2012 should be plenty of scope for detail in the cockpit Edwin, look forward to seeing how you get on looks really good by the way Cheers Danny Quote Link to comment Share on other sites More sharing options...

Peter Clinch Posted November 17, 2012 Share Posted November 17, 2012 Hi Edwin Nice article I have just started building this kit. Can you tell me what servos you used on the wings.? Thanks Pete Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted November 18, 2012 Author Share Posted November 18, 2012 Good morning Peter, Enjoy the build. I use New Power XL-16HM servos for the ailerons. It looks like is going to be a rainy day here, so I probaly spend some time working on the Corby. Edwin Quote Link to comment Share on other sites More sharing options...
Ton van Munsteren Posted November 18, 2012 Share Posted November 18, 2012 Hi Edwin, Any progress, looking forward to some more pickies. Ton Quote Link to comment Share on other sites More sharing options...
Edwin van der Maat Posted November 25, 2012 Author Share Posted November 25, 2012 Goodevening, the progress has been very slow, due to work. Well, installed the servos. Started with preparring the pieces of grey carton to create the cockpit finish. Enough choice of instruments...... The Corby instrument panel consists of two pieces. The original used a grey panel, so I used the grey carto to start with. Then, I stick the seperate instruments with tape to the back of the carton. After that the panel is glued on 3mm balsa. Yes......some glue seeped through, but luckily this is behind the center panel. Glued the panels in place. Added a piece of fuel tubing to the skin edge above the instrument panel. This still needs to be painted. Next is add horizontal grey carton pieces against the instrument panel. On this part, I have to put some switches, communication radio and GPS. After that is painting the rest of the cockpit and add the seat..........enough to do. Best regards, Edwin Quote Link to comment Share on other sites More sharing options...
