    I'm back. After holidays and some other important things I had to do, I can now get back to my project. There were some changes I decided to do, regarding the mounting of the main wing. Originally I stated, this will be bolted to the fuse by four bolts but decided to use recommended method, using dowels in the front and two bolts in the trailing edge. Reason being, more space in the front. Also, my wing supporting struts will be functional, so there will be more than adequate strength to hold the wing in high stress turns.
    I started with the saddle by making a template from the paper then cutting balsa sides and finally sheeted the whole top. After making, and fitting dowels in the front, I checked the symmetry of the wing in relation to the fuse, then drilled 6mm holes in the back, using blind nuts on the bottom, bolted the whole thing together.
    There are always small imperfections in the seat, so decided to use a new method of making the saddle surface smooth and gapless. This time I used Gorilla glue, which has not only excellent bonding properties but it also swells as it dries. I have smeared generous amount on both saddles and covered it by (my favourite) baking paper strips. After this I bolted the wing in place, nice and tight. This will fill up all empty spaces between the saddle and the wing. Now I have to wait until it dries.

    Thanks Maekju, I'm being held by work big time. So, this is going a bit slower right now. The wings are finally where they belong, with +1 degree incidence. I might start on UC next. Get the fiddly bit out of road. I still have a lot of work to do on wings. Glueing rib strips, cutting ailerons and building up servo bay.

    Finally, started concentrating on UC. I had to think about it 'cos if I just joined the two sides together with a little trim at the fuse, I wouldn't be able to remove my clip on belly pan I built earlier. So, I decided to glue vertical sides from balsa, at the root of the UC and basically the inner half will follow. This small cut off will enable me to lift off the pan and therefore remove entire UC if I have to. Also carried on with the wing servo bays and rib strips. Once that's all done, I will cut the ailerons.

    I have glued balsa strips round the perimeter of the fiberglass fairing half for better hysol bonding. These fairings are unfortunately not very accurate but I have them, so I better use them.
    It looks a bit messy but after hysol cures, I'll have to do some trimming, sanding, gap filling, more sanding etc.

    It's amazing how much I get done with a bit of spare time. The UC came out better than I thought it would. All I had to do, is clean up the edges with fine sand paper. I'm quite happy the way it came out.
    Now, for the transition into the wheel spat. I have already drilled and tapped two holes M4 at the base. The whole end bit is now covered with 2mm ply. I used microbaloons to fill up the spaces. This will be sanded to a smooth finish. While this is all getting cured, I'm doing some more work on the wing and fuse stringers.

    Oh, I only wish I could build like a pro ��. Doing stuff by hands is never going to be super accurate. At least not with me��. Luckily, we have great products available these days to make our work looking better. Balsa filler, super glue, microbaloons with epoxy, hysol, etc and a various sanding tools. My theory is, as long as the entire frame is geometricaly and structuraly sound, small inner imperfections are unimportant. Once you sand everything to a smooth finish and then apply the covering, no one will ever know.��

    You've made great progress in 4 months time. Do you have an estimated time of completion?

    Maekju, I have no idea when I finish. Things keep changing and I don't always have that much spare time but would loved to maiden it this winter. I'm talking about Australian winter in Brisbane. Nice cool wheather and not so hot.

ID:	1977005My appology for not posting, my computer crashed out and I lost a lot of valuable info. Needless to say I spent many hours hoplessly trying to restore what I have lost. I have done some more progress. Made rudder servo compartment between the main wing and the stab, finished off the fuse stringers, mounted cowling, located and mounted the engine after making some spacers.
    I'm a bit shy of pics right now but soon as I sort out my iMac, I'll be back on track.

    I have the problem with pictures coming out upside down when using my Iphone. Sometimes they show right and sometimes not. I forgot what the cause is but I think it has something to do with how the computer displays the photos.

    My computer is restored as well as access to this web site (long story). Anyway, here is my latest progress. I started working on a cockpit. Also you can see the mounting of my engine. I had to make extensions as well as mounting the engine in a slight angle. The reason is, to make more room for exhaust header pipe.

    In post #83 you mentioned doing things by hand, I know there's some power tools in your shop. Your build looks very accurate and clean.

    Hey Maekju, yes I do most of these parts by hand. I don't know which power tools you are reffering to. The tools I use are little dremel, electric vibrating sander, pedestal and portable drill and jigsaw. All these I use mainly to either drill a hole or attach a sanding disc. Rest of them are non power tools. Files, blades for cutting, hacksaws, straight edges, rules etc... I'm stagnating for a little while at the moment, I'm waiting for wheels and lexan (polycarbonate) sheet for canopy. I will make attempt to create a pilot figure as well.Hmm..that'll be fun, I have never made one. Right now, I'm away on business trip, so more delays.

    I started on a pilot. This will be quite challenging task. I have found one of those high density yellow foams at work while unpacking one of the deliveries. I thought, great I can use this to make pilot.
    I will try to follow what other people have done. First of all I have to sculpt the figure kind of rough way. Here are mine first attempts. Don't laugh, he is going to be improved by either using clay or one of those epoxy putties.

    Some more progress. I have covered my pilot with clay and will try to produce some more detail when it starts hardening a bit. This is harder than I thought. Also, decided to secure my cockpit before I start laying balsa planks. At least it's fixed and it can't move. I also decided to finish off my instrument panel and glued it in place. It's all a bit slow now. Once I get through this cockpit job, I will move on to aileron cutting.

    Thanks Calvi, I still have to make him headgear and goggles straps. Once that's done I'll make his face texture a bit smoother by using steel wool. Making mold will be the next move.

    Here, I have added some straps. Now I have to wait until it all dries before sanding and painting the mould release agent.

    Finished off planking cockpit and reinforced the mounting phenolic horns. This part needs lots of sanding and filling. Also my wheels arrived today, so I carried on with the UC fitting wheel spats in place, with the correct angle. These things are huge, which is typical of golden era racing planes.

    Today I spent a lot of time sanding and filling. Such is task for a scratch builder. I have now prepared cockpit for covering. It got one coat of dope and fine sand. I also made removable bracket to locate my tuned pipe. Just decided, before I cut my ailerons, I will make wing spars with the wing attachment cover. This will have to be moulded either using cardboard or making a mould. Again, I'm jumping between jobs and I do what can at the time. I can't finish the UC, 'cos I need to buy right size collets to secure wheels.
