What you need to do brother is create driven pathways, places where the grass is trampled down along a vehicle track... The vehicles would always take a path repetitively and would wear down the grass eventually turning into mud paths.... Much like your mud puddle... They would be wider than the tires by two or three times, of course the grass on the airfield never got that high in the first place, but in the traveled areas and passage tracks it was always laying down... from being driven over...

P-51D Mustang by CDW - FINISHED - Dragon - 1:32 Scale
Egilman replied to CDW's topic in Non-ship/categorised builds
Yep the Vaunted Mustang.... The equal of any airplane in the sky below 18,000ft but she really showed her props above 20,000..... Nothing could outrun her or out maneuver her in the high sky... It took a jet propelled aircraft (Me262) to finally surpass her capabilities... After the war was over the USAF retired all other fighter aircraft in favor of her.... She wasn't downgraded until the F-80 Shooting Star was accepted into service.... She is still to this day the hottest propeller driven aircraft in the sky... (and a damn fine looking girl to boot) -

Another update... Steering gear is basically done... Some minor details to add.. And might need a bit of tweaking once the firewall is built but it's basic design is complete... Reverse angle view... And an overall right side 3/4 view.... We are getting closer to actually building something... {chuckle} I guess the firewall is next.... then I can adjust the gear box to it's final angle and install a steering wheel.... Anyways, the journey continues.... Onwards... -
Krupp 420mm Big Bertha by Haliburton - Takom - 1/35
Egilman replied to Haliburton's topic in Non-ship/categorised builds
Yep, History is replete with them, all eras, all societies..... It's the reason for Ike's famous piece of advice to Jack before Jack's inauguration, "beware the military-industrial complex"..... Play ball or you don't survive... -
Krupp 420mm Big Bertha by Haliburton - Takom - 1/35
Egilman replied to Haliburton's topic in Non-ship/categorised builds
Yes they officially made railcars, but in reality the factory was "sold" to Bofors, and they continued to make guns under the Bofors name until about 1934 when they finally bought themselves out of it and a year later bought Bofors itself... Krupp was one of the most powerful industrialists in the world like Ford, Benz, Messerschmitt, Westinghouse, DuPont and several others... The normal rule of law doesn't apply to them... -
Issues like this is why I gave up on paper modeling.... Plenty of ways to fix this type of thing, but it's next to impossible once the skin is glued in place.... And you generally don't find this type of stuff until it is in place... Halinski's can be a challenge... Absolutely gorgeous when they go together correctly, frustrating fire lighters when they don't....

Russian modern armoured vehicles by Baker - ACE - 1/72
Egilman replied to Baker's topic in Non-ship/categorised builds
Battalion sized, one for each nation.... Stunningly beautiful.... -
Yep Moskit, They were just as difficult to find as REXx sets today are... I guess you could call them 3D printed in a sense, but what they are is electroplated over a master form, then the form is melted away leaving a very fine metal shell... This is why they state they are "grown" rather than printed... They (Moskit) were the thickness of tinfoil... (it's why they looked so realistic) I've been told that the REXx sets are a bit thicker but not by much.... Moskit died a quick death when it was discovered that their parts were so fragile, you had to be careful even looking at it... REXx has the same reputation.... Also, when they say they are designed for a specific model they mean it... You will have a very, very difficult time adapting/modifying them to any other kit... Most modelers I've inquired about them would not recommend them... Museum quality looks? yes, Very difficult to actually use without destroying them? yes, Worth it in the long run? opinions vary... Don't dispose of your kit exhausts until your completely done with the kit, there are any number of reports on REXx sets getting completely destroyed beyond repair by just picking up the model in the wrong spot... Personally, not worth it in my opinion....

P-51D Mustang by CDW - FINISHED - Dragon - 1:32 Scale
Egilman replied to CDW's topic in Non-ship/categorised builds
A Silverbird.... A legend in it's own time.... Probably the greatest single engine, propeller driven fighter plane ever built... Of course I'm down for this one, wouldn't miss it.... -
Good question... The prototype didn't have them, the modified 14-bis did... Greg, since none of the original drawings exist, it's a guess... It's one solution that results in what was described in the period literature, and it fits the materials and techniques of the period... But was it "THE" solution there is absolutely no way of knowing.... Now the guy that's got one flying replica down there in Brazil, is using actual ailerons, which allows him to fly it as the ailerons do work as they are supposed to... Still herky jerky as that is the design limitations, but what he is showing is how close Dumont was getting to actually having a truly flying aircraft... I believe he would have sussed it out in a few months... Period pictures do show the flat panel ailerons in it's later life, so they are period correct, but the film of the period doesn't pick up details very well... (it's why the Wright's painted their machine in cadmium paint before going to Europe, they knew that the monochrome film would not pick up the control setup against a silvery monochrome background) It's why there were a lot of copies of the Wright airplane built in Europe, (based upon the pics) but they couldn't get any of them to fly like theirs did so the design was rejected by the Europeans.... {chuckle} Any way it turns out my friend, your building a beautiful model, don't let the vagaries of old history stop you...

Well, going over what is next, I need the firewall to do the steering and accelerator pedal... SO in getting the little things done first, I decided to add the Steering Linkages, the Steering Knuckle off the right spindle and the Pittman arm off the steering box, then the steering gear box itself... I need the Gear box in place cause it sets some of the angles needed for the steering wheel and it's support structures.... I need the firewall in place cause it sets the location of some of the accelerator linkage details.... And all that before I need the Carburetor.... So finishing off the Engine gets pushed back a little more on the schedule... Anyway, here is the progress on hooking up the steering.... This image shows both arms in their relative locations, the drag link connecting the two comes next... Location of where the Gear Box will be built.... The long cylinder is the output housing of the Gear Box and that strap looking thing bent over the housing on the left is the beginnings of the frame clamp.... Just a short update today brothers... Onwards... -
Check this video out.... Has some very detailed views of the rigging and the control system..... What I saw was a wire connected from the top wing to the aileron with a shrouded spring connected to the bottom wing... The cable runs vertical to the wing through a sheave then along the wing surface through guides to a point almost at the pilots position where it is connected to the ropes that the pilot looped over his shoulders.... And, as originally built, No Ailerons at all....
-
Ok Those images are not available from any repository I have access to.... But what I can tell you is the craft was built in 1909 never made a flight longer than 220 metres, and it only made 8 flights in total before it was completely destroyed... the "Ailerons" shown on the kit were added after it's third flight to improve roll control and were simply straight fins intended to redirect airflow and weren't true ailerons as Curtis created them... And it's last five flights proved them ineffectual.... It was also the first in europe to be considered as actually flown rather than lurching around in the air like a drunken pigeon.... There are many people who claim that he was the first to fly, but even he acknowledged that his inspiration to get into heavier than air craft, (and away from dirigibles) was the reports of the Wright's and what they were doing around Hoffman Prairie in 1906-07... (circles and figure eights and flights as long as 10-20 miles)... When the Wrights finally went to Europe in 1908, it was Dumont who famously exclaimed, We Are BEATEN!!!! very loudly on the very field (Lemans) where the first demonstration flight took place... Dumont understood that control in all three axes was the achievement and that no one in Europe had arrived there yet when the wrights first flew at the Paris Exposition...
-
Yeah, he was figuring out CoG right about then, but they still missed the even more important aspect of balance around that CoG... At least they had got away from those horrible twin main wing monstrosities they were trying to fly.... Dumont was the closest of the Europeans gaining an understanding of control in three axes, but the Thomas Edison approach to the engineering was slow going.... And it wasn't long, everything was published back in that day as it was believed that science was for everyone... How it works wasn't patentable, how to make it work was... Everyone wanted to be the first to really "Fly" like a bird... I personally believe SD had just about figured it out, and then saw the Wrights working solution in Paris.... It didn't take long after that for everyone to figure it out... Dumont's subsequent airplane work after that was proof of concept, and when he established it to his satisfaction, he stopped... I believe his stopping work was a major loss to science....

Another small update... Clutch Pedal and it's mechanism.... Only roughed out at this point, I still have to figure out how it attaches to the frame.... But, as far as the driving Brakes connection, I found this... Lower right corner, in the background just above the clutch operating rod, is the clevis that attaches the brake rod to the clutch pedal.... looks like a little round bearing on a triangular tab on the back side of the pedal arm... A look from the right side... And a direct left side view.... So that leaves the right side pedal in the cockpit as the accelerator pedal.... So I'll finalize this addition, and look at what's next, probably the engine cause the intake needs to be complete and the firewall installed before I can address the Accelerator pedal... (it is a lot simpler than the clutch pedal) Onwards... -

Well, another little piece... The brake isn't set and the tranny is in neutral..... And the overall look from the right side.... The next and final step to getting the operating controls all hooked up, (except for the Steering) is the Clutch linkages, Throw-out bearing and forward universal... (which is represented by those two conical discs in the frame bay behind the conical clutch... The Clutch pedal is mounted in the engine compartment... The clutch is actuated by a linkage from the engine compartment to the cockpit which operates a torque tube to rotate the throw-out bearing which carries the clutch away from the flywheel... The Clutch pedal also operates the driving brakes and is adjusted to engage after the clutch has disengaged... They were a pain in the you-know-what to keep adjusted correctly.... I don't have an image of the linkages used to effectuate this for this car, but I do have such for the 1911 National model 40 which was set up identically to this car.... (a National Model 40 won the 1912 Indy 500) This brake setup was standard on these race cars during this period, the civilian production variants were set up differently with independent brakes.... Anyways, Onwards....
