Peter Miller Posted November 8, 2016 Author Share Posted November 8, 2016 No pictures of today's work but I spent an interesting day planking the top half of the fuselage. some 26 planks. Got about another 20 to go once the wing has been fitted.. Also discovered a silly mistake with the U/C mounting. Easy to modify on the plan but not my model but I can work round it. Planking is strangely satisfying. Quote Link to comment Share on other sites More sharing options...
Geoff S Posted November 8, 2016 Share Posted November 8, 2016 I agree about planking, Peter. I've never planked an aeroplane but the bow and stern sections of my barge are planked and the stern particularly is quite tortuous. The main hull is a simple flat sided box for maximum load and the ability to take the ground when the tide goes out in the east coast rivers. I really wish you'd stop publishing such attractive designs. I've got a long enough building queue as it is. Geoff Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 9, 2016 Author Share Posted November 9, 2016 Sorry Geoff but I get these sadomasochstic tendancies at times Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 10, 2016 Author Share Posted November 10, 2016 Quite a bit more done now, skipped one or two stages but the results are here. The top of the fuselage was planked without the wing of course. This side shows some of the hundreds of map pins used. A total of 26 planks so far. This is the other side with the pins removed. The idea is to plank right up to the wing to save trying to trim this to fit later. I will also build in the root fairings at the same time. This is the bottom view of the model so far. I have just added the belly formers. I made a slight goof with the undercarriage going right in to the centre. IT will end at R-2 in the final version. THis is the view at the tail showing that the planking actually suports the tail surfaces. Covering is going to be a bit of a pain Edited By Peter Miller on 10/11/2016 21:07:42 Quote Link to comment Share on other sites More sharing options...
john stones 1 - Moderator Posted November 10, 2016 Share Posted November 10, 2016 Very nice Peter, you'll enjoy sanding that fuzz up Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 10, 2016 Author Share Posted November 10, 2016 Oh Yes. It goes from a grotty looking mess to a thing of beauty in a few miniutes. Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted November 12, 2016 Author Share Posted November 12, 2016 I finished the planking today and started sandpapering. Also did the root fairings. I also weghed the model as it is in the photos. It weighs 1 lb 9 1/2 ounces. I am rather pleased with that. Quote Link to comment Share on other sites More sharing options...

Geoff S Posted November 12, 2016 Share Posted November 12, 2016 Without the hump at the front it looks very like a Westland Wyvern. I remember them from when I was in the Naval section of the school CCF and we visited RNAS Stretton in 1955/6 a couple of times. They seemed enormous alongside the Sea Hawks and almost matched the Fairey Gannets. Geoff Quote Link to comment Share on other sites More sharing options...

Peter Miller Posted November 12, 2016 Author Share Posted November 12, 2016 Actually while I was working on it today I looked and thought P47 Thunderbolt. Possibly influenced by watching the beginning and end of "The War Lover (The middle is total rubbish!!) where they used P47s as enemy fighters.

Delta Foxtrot Posted November 12, 2016 Share Posted November 12, 2016 Posted by Maurice Harvey on 05/11/2016 18:59:33: Posted by Peter Miller on 05/11/2016 10:54:23: Colin. Yes, there is my standard 2 degrees of washout. Ithas worked perfectly on five model with ellitical wings so far. The wing is designed on Compufoil and is created to the "That looks about right" method. In fact I used the jezebel wing and stretched it here and there to get the size I wanted.. In passing, When Mitchell was asked by his staff what shape the wing should be his answer was "I don't care what shape it is so long as we can get the guns in." so the elliptical wing credit goes to someone else. L.P.Pete Well there are a lot of 40 Surpasses around still and not too expensive. SC do a .52 which is a great engine. Mass build? Somehow I don't think that there are enough masochists around for that but you never know, modellers do tend to be masochistic at times, Peter, You are quite right when you say that the credit for the spitfire wing belongs to someone else. His name was Beverley Shenstone,1906-1979, a Canadian who was part of R.G,s design team. But, I expect that you already knew that Peter. And almost certainly Shenstone got the concept of the elliptical wing from his time working in Germany in the 1930's. The advantages of elliptical loading were first recognised by Ludwig Prandtl and his colleagues at Gottingen at the turn of the last century.

Trevor Crook Posted November 13, 2016 Share Posted November 13, 2016 Peter, don't worry about us sparkies, we'll always find a way - my Ballerina is great with EP. Plus, if we want a sleeker look we can leave off the cylinder head hump. I'll reserve judgement on that until I see your finished prototype. Removing the hump could ruin the character, plus it looks a great location for the ESC. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 13, 2016 Author Share Posted November 13, 2016 Delta Foxtrot. Interesting how much the ideas travel round. Lippisch and Horten did so much work on flying wings.. Trevor I think the cylinder fairing may or may not improve the looks. A matter of taste. I have not made up my mind but I am committed Not too sure about battery sizes but you should be able to get one in. I just checked on the Overlander Website and you can get a 4400 MaH 4S 14.8V battery in. without major mods Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 17, 2016 Author Share Posted November 17, 2016 Well, got quite a lot more done. The fairings are made by trapping 1/64" ply between the fuselage and wing. Then adding the small formers. Then 1/16"balsa is wet and fitted. The rest of the fuselage is planked and the wing can be removed. That makes things so much easier. Now starting construction of the cowl. My usual method of working between the nose ring and F-1. In this case The is a separate former as the cowl comes off forwards. Fitting the first of the 1/2" sheet between those formers. Side sheet added. The rest of the parts ready to be fitted. The sides arelaminated from two layers of 3/16" sheet cross grained as a lergin slot has to be cut for the enhaust exit. The basic cowl assmebly. IT will not look quite as bas when finished but I have to say that it looked so much better without it. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 17, 2016 Author Share Posted November 17, 2016 Some more of the wing has been done. The wing fairing has been trimmed to final shape. Don't forget to fit the snakes before planking. It does allow you to do a nice fit at the snake exits. Still some snading and shapid right at the rear end. Underside of the wing showing the undercarriage grooves.I took them in a bit too far. On the final version they will end at R-2 so can be removed without damaging the belly. The holes for the wing bolts. These will have thick rolled paper tubes lining them. Bellcranks are fitted out in the wing. I like keeping the weight away from the wing tips. And that is progress so far. well as far as the photos go. Quote Link to comment Share on other sites More sharing options...
Colin Leighfield Posted November 17, 2016 Share Posted November 17, 2016 It's looking like a real classic. I think you should stick with the engine cowl design. You decided to produce a plane with the style of a thirties racer and that's exactly how a plane with an upright Gypsy air-cooled four would have looked. If you didn't do it like that, what would the alternative be? A Gypsy the other way up? An air-cooled radial? A flat four? Etc, etc. Time for experimenting when a few more get built!

Peter Miller Posted November 18, 2016 Author Share Posted November 18, 2016 IT won't look quite so bad when the fairing behind that lump is done. Possibly an apple cheek cowl would look good bu they are a lot more work (I am lazy) Then the head rest ans windscreen will make it blend in a bit more.

Josip Vrandecic -Mes Posted November 18, 2016 Share Posted November 18, 2016 Hi Colin and Peter , Yes of course.... the classics.... that most contributes to the impression the engine, which since last fall to the ground, was not touched at all. Regards both Edited By Josip Vrandecic -Mes on 18/11/2016 12:19:05 Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted November 21, 2016 Author Share Posted November 21, 2016 Hey, I am ready to start covering. For a start, this is the insides of the rear part of the engine cowl I was a bit worried that the cowl would spoil the look of the model but I don't think that it has. That slot allows the cowling to come off forwards over the exhaust system. I didn't hang the tail bits on for these pictures, Not too bad for three weeks work.

Colin Leighfield Posted November 21, 2016 Share Posted November 21, 2016 That looks excellent Peter, it would certainly pass for a scale model. To say that it's not bad for three weeks work is something of an understatement! Quote Link to comment Share on other sites More sharing options...

MattyB Posted November 21, 2016 Share Posted November 21, 2016 Agreed, with decent lightweight servos for a model like this so cheap now bellcranks really aren't worth the effort. Still it would be trivial to mod for two servos, looks like there is plenty of room. PS - I really do like the looks now the cowl is finished. Maybe that could be modded to form a battery hatch for an electric conversion? Quote Link to comment Share on other sites More sharing options...
