    PC-9 / Texan II

    The two pictures of the "kinked" tail are actually PC-7Mk2 aircraft, now called PC-9M. The PC-7Mk2 was developed from the standard PC-9 for the SAAF in the early 90's. The "7" was used instead of the "9" in the designation due to the downrated performance, and a good dose of politics.... As to the differenced between the original Swiss and the American built version: plenty. Canopy is larger and has the alteady mentioned extra frames. Also note the spinner is bigger and thus the whole air intake and nose have some slight differences. Different ejection seats too and the ventral fin difference.
  2. Normal automotive brake fluid, usually the cheapest works best (not synthetic one, that dont work). I prefer brake fluid over other chemicals as it does not smell strongly and is easy to apply and sticks to the surface, as it is oil. Takes a night or so to work on the paint and glue. It also makes the plastic a bit brittle if left for more than 2 days. Clear parts also frost a bit, but is quickly polished out. Of course it is also important to then clean the parts afterwards with detergent to remove the remaining brake fluid. R
  3. Awesome, great to see someone with a similar mission to mine... Currently I am dissassemblying and cleaning a number of models built whem my skills were not all that good. I usually use break fluid to remove the paint, as it also desolves the glue joints.
  4. "Libelle" is the more commonly used word for dragonfly. R
  5. Nice build! I actually found mine easy to build; the trick is to add a few extra location tabs to force the parts into position. Built mine in aabout a week. Painting was however another issue, lots and lots of gloss white!
  6. I was fortunate to attend the OT&E in the SAAF as a civilian a few years back. Course members were mostly fighter and helicopter pilots. During one lunch the conversation turned to forced landings. No one had done a real one, and everyone was dreading the concept. I cassually observed I already did 52 forced landings. 9 pairs of saucer big eyes stared at me.... Untill I mentioned all of them were in a glider, however there was a awe that remained with the fellow students.
  7. Well done on the weathrting! Well balanced and characteristic of the real weathering patterns.
  8. I think the colours are actually very close to an operational aircraft. The "dark earth" bleached quite a bit. Just a sugestion: you can try to slightly town down the colour even more by adding a very light mist of pale grey once all decals are on and the matt coat is on and dry. I have the same kit, built many years ago, which is up for restauration due to the brown being dark earth and not the actual lighter shade. So I'm following with interest....
  9. Giving me ideas with the air brake.... Well done! If you do find that article, please post? Will appreaciate it much. I am a bit of a sucker when it comes to moving parts on models R
  10. If I may chirp in here... Refering to the test fits of the VGs on the wing: note that the VG's are mounted at an angle of about 22 degrees (if memory serves me correctly) relative to the longituinal axis. Since you are going into that insane amount of detail.... Interesting also, at least on the Hawks that I had to measure up, is that the bit of the angle that gets stuck to the wing surface is sometines inboard and sometimes outboard. Always consistent per airframe, but different accross the fleet. The exact spanwise position also varied. However the chord-wise position is perfectly fixed. Interesting approach to your modelling detailling - you are setting a verry high challenge for the tripplet of Hawks I am planning. This is a fascinating thread, keep it going! R
  11. Was never that much a fan of the turbine version of the Goose, those inverted engines and un-aesthetically long cowlings put me off. Hence the thought experiment if a stretched Widgeon will look a bit better....
  12. That wing would immediately crash onto tha tail if released. I worked on a glide bomb once that would jettison its wing prior to going into the dive onto the target. The wing would innitially sepparate, but having no stabilising tail woulld immediately pitch down and fly into the mothership. The wing would need a leverage arm to force it over the top and behind the aircraft. R
  13. Here is my rendition of Airfix's little Albatross DV built OOB in the colours of Baron von Richthofen. The first OOB build did in um dunno years at least.... I could not help but improve the kit a bit by scratch building the Daimler engine, making the prop from laminated Balsa wood and making the Spandau guns myself. For the latter I used a very fine mesh to represent the cooling jackets. Not perfect but in that scale it does the trick. Smaller improvements are an instrument panel and compass for Manfred. The rigging I made from very fine Tungsten wire not the ideal solution. The whole system of plastic wings and Tungsten wires is somewhat temperature sensitive, causing the wires to sag at times. I still need to get hold of something stretchy to keep the bracing wires tight. What first pulled me towards this build was the natural plywood of the fuselage I wanted to try and emulate that. I am in two minds about the effect I created; sometimes I think I over done it and other times I think it is way too subtle. But be it as it may, it is done now. And it is a colourful addition to my little collection of models. And a bit of detail of the scratch built engine, prop and Spandau guns: R
  14. Here is a “What if” model of mine. Not that I normally do this kind of modelling, but as a thought experiment I wanted to see what it takes to convert a Grumman Widgeon to turbine power. I started this build as part of the what if group build of last year, but only completed it recently. Here a link to the build, with some info on the conversion of the model itself. Link To recap though on the concept: Stretch the fuselage ahead of the wing to make up for the slightly lighter engines, but also stretch the rear fuselage a bit – to increase control authority of the tail feathers. Or increase the “tail volume” as it is technically called. The trick is finding a balance between the two. Increasing the tail authority is required due to the increased powe;, to allow controlled flight with one engine out and to also counteract the now increased aerodynamic forces the extended nose will give. Also a fin root extension will be given for the latter reason to help in cross wind landings. The engine nacelles have to be extended a bit to fit the turbine engines. And also to keep the prop discs ahead of the flight crew stations in the now extended front fuselage. Wings were modified a bit with different flaps and winglets to increase the wing aspect ratio. I’m happy the way the concept worked out – so if anyone has a spare Wigeon airframe and lots of money available, I can convert it to turbine power for you. I didn’t do too much effort on getting the model to a perfect finish – I needed a bit of a fun build for a change as well. And I had fun with this build! The colour scheme was inspired by the Grumman Goose used in “Tales of the Golden Monkey”, if any one actually knows of that TV series....? And what she looks like with wheels retracted. Still want to add a little base of water for it - something like a peaceful Canadian lake diorama or so... R
  15. Unfortunately not with me - the model is also in a different country from where I live and work at the moment. Otherwise I could quickly take some photos.... R
