I bags first pax privileges Dave. I think I can squeeze into the slick fuselage.

Good to see your progress Dave. Have you tried to fit the wing into the fuselage yet. No! go on, I know you're dying to and we're dying to see it.

IF that's not a 'photoshop' job, it's a job well done. About the only thing that would give it away would be the white of the spare wheel not lining up. Depends on your relative position.

I'm asking about the one that isn't connected to the engine. Grbg handle perhaps?

Enjoy this beautiful, and accurate model Lightning, complete with reheat FX. 92 Sqdn shared air-space with 19 Sqdn at Leconfield when I was with 19.

Whilst we're on that subject...........enjoy.......female friendly.

(Except for the stupid wind turbines, they are not an achievement but a retrograde step). Not retrograde, there are a stepping stone to the future. One day, they'll be gone.

Just so that you don't annoy cell phone haters like me. God, if people can't live without the damned things for a few minutes, what hope is there for the human race. Same goes for when driving cars.

Gees, how old are you. I'm72 and it's always been RAF 'Upavon' to me.

That looks suspiciously like Paul Bertinaly (spelling?) to me.

Was never thinking of type certification Bob. This is a one off for sure.

BTW, you think a 'windswept UK' is bad, we've got to contend with this. View the current warnings for South Australia Forecast issued at 5:20 am CDT on Tuesday 28 January 2014.

BRISTOL BEVERLEY'S, sacrilege. Blackburn lad, Blackburn.

Well done mate, wish my wife would come up with me. Say's she's not scared but doesn't want to be air-sick. (Never has been on our overseas flights.) Taking passengers is a real thrill and here are a few of mine. Crazy neighbour Ex boss and major stroke victim Our chemist Cancer survivor Niece Unfortunately, like you, I didn't take one of my then 89 year old, partially blind, mother. Her only comment, cabin service not as good as Qantas. Enjoy your flying and share your enjoyment.

Thanks for your comments guys. Now the come back. TP, yes too much prop blanketing and I intended for a more pointy rear end but ran into two problems. First was that I've been experimenting with a new addon to Google SketchUp called Curviloft. This program adds a skin to per-constructed 'formers' or stations. It sounds easy but in reality, if you don't get the stations right, the skin takes on all sorts of weird forms. I lost control quite a few times and my design suffered somewhat. I'll be trying for a better shape shortly. The second reason, and more believable is that, for mechanical reasons, I don't want a long prop hub. Therefore I'm stuck with close proximity of prop to fuselage. As you say in your second post, a ducted prop etc is too far away from what I want so no, not going that way. The possibility of losing the boom and tail assembly has been raised in many discussions on this configuration and my basic answer is, a) build it strong, even at the expense of weight and speed. Choose bearings that will be under running their normal speed and load specs. b) Fit a ballistic cute. As far as I know, there's no previous design using the bearing method that I've designed. Most mid prop systems had a small bearing on a thin tube which necessitated one or two extra stay to hold the tailplane. Again, not what I want. Bob, yes my boom and feathers was too small. When I first set out on this redesign, this assembly was the first to be completed. I was working from "this looks right" point of view. Later, the fuselage turned out bigger than I thought and I never really looked closely at the comparable sizes. I see now where you're coming from so I've scaled up the rear end and, I've taken 10 degrees dihedral (anhedral? not in dictionary) from the horizontal stabs. I knew that the 120 degrees between surfaces was wrong but, being pig headed............. Re shaping the fuselage will help re vortex separation etc. In a perfect would, I would go as far as a pair of contra-rotating props to cure many concerns. I personally think that c/r props should be allowed if on the same axis. Just call it a single 'Propulsion system' not 'twin props'. Yes I know, hellish heavy, expensive and complex..........but doable. As for the stall comments, I don't think it will be as bad as you intimate. the prop only covers about 16% of the total wing span and most of that is that section through the fuselage. Actual wing surface would be about 7%. I have more concerns about the same area having a negative influence when the flaps are lowered. Note that I have a 3 bladed prop so only one blade affected at any moment in time. I have looked at Taylor's Mini-imp but even he had trouble, mainly in the long drive shaft required. Again, I'm not looking for a clone. Would morphing control surfaces need mass balancing? Birds don't have them Guess that's going to be a wait and see type of thing. A more considered answer is that most control surfaces are hinged on a central axis and need some form of dampening from time to time. My system can't flutter as it's driven from both top and bottom simultaneously, side to side in the case of the rudder, and will be much stiffer than conventional. To appreciate that statement, take a piece of paper and fold it in half. Hold the open ends to form a control surface and then push/pull to activate the curve. That's the basis of my design. There is one big drawback however. The surface must have a constant X-section which negates tapered depth wings and tail plane surfaces. Looks particularly ugly on the tail surfaces unfortunately. Under-carriage will probably be wood and fiber-glass composite. Why do you specifically ask that? Ah, thinking of prop strike in the case of a hard landing perhaps. The idea is not to land hard Bearing in mind that all things can change, does this look better?

They didn't, Hitler did.

G'day tlamdweeb, welcome to the forum. Your last post reawakened fond memories of Yatesbury, in it's day as RAF Yatesbury, an air-radar training station. I spent many months, years, there completing various courses. I've just had a look on Google Earth and am happy to see that at least some of the site still remains,ie the hangars. God I hated guarding those in the depths of winter (we all had guard duties from time to time). Just done a search and the only images I can find of Yatesbury in it's Heyday are from the late 40's or early 50's. I was first there in 1960 but not much had changed. Some horse play between classes. I'm bottom row and struggling on the right. Graduation to Junior technician. I'm 2nd left. Ah happy days.........................mostly.

Best with full screen, phones and a cup of coffee. Long , beautiful video. Enjoy. http://www.flixxy.com/germany-from-above-1080p-hd.htm

I'll raise you to 4 Sqdn badges

Bill, I already have cooling concerns, whatever engine I use. Air-cooled for lightness but, top draft or bottom. Intuition tells me to use normal convection theory and go for a low inlet, high outlet and let heat rise. The problem I see with that is heat from the exhausts will impinge on the cylinder heads and cause a problem there, regardless of engine make. If there happens to be a motor that has the exhausts on the top however................. As for where intakes are placed, it seems to me that on the bottom is best and leave the upper fuselage clean for aerodynamic purposes. This would mean a lot of internal ducting and airflow losses. Like I said, lots of work to do. Re the cockpit, yes, I to like a clear view. For access, the canopy will hings to the right, together with a minimalist inst' panel. The screen will be a one piece wrap round poly type. Construction is wood and fibre for the fuselage, and alloy and fibre for the wings. The canopy may have an alloy tube running around its periphery to add some stiffness.

G'day guys. You know that I love to dream and design new planes with the hope that one day I'll actually be able to build. Well, I've returned to my first off ever design and updated it. What do you think. Introducing the DeMansfield Bolt Mk ? Originally, this was to be a mid to shoulder wing but I've had to go lower to fit the wings. It will have a tricycle under carriage with a retractable nose wheel and differential brakes for ground steering. Probably be powered by a Jabiru for lightness, driving a specially made prop, around the tail boom. There's no contact between the prop and the boom. All control surfaces will be fake 'morphing' (shape changing) and not hinged as per normal. It will have extending and drooping leading edges, extending and 2 stag flaps, and hopefully, (nearly)seamless ailerons, elevators and rudder. Most of it is designed in my mind having spent countless hours working and reworking the details. Yes I know, morphing surfaces will be heavier and more complex, but due to their increased efficiency (no gaps), will be more efficient and therefore can be smaller. The boom and tail-assembly are removed in one piece and each wing is removable for towing purposes. It should all fit into a double horse box or similar trailer. This is early in it's development and there's a lot of work still to do.

Impressive production numbers. Bath Iron Works delivered a completed U.S. Navy Destroyer Escort ship every 13 days at the height of WWII....... BIW alone built more Destroyers than entire Japanese Navy had afloat..... NOW YOU WILL KNOW.....
