    Hello Aleatorylamp, My belief is that it was actually the glue assembly sequence that cured the cabin bleeds. The location of the cabin's aft bulkhead wasn't really the issue in my opinion. I moved the CoG to that location because it really should have been around there to begin with. Note the lift points on the Paul Matt drawing. Please note that the cockpit aft wall usually does not coincide with the CoG. They almost never do on the single seaters with the cockpit well aft of the CoG and it doesn't on my MitchellC either and the cockpit is well forward of the CoG. Glad you like the AIR file. I actually have very little idea how that aeroplane flew. I was just basing my tweaks on hopefully reasonable guesses and trying to discount the greater exaggerations of the actual...

    At some point I will also need a set of Manifold Pressure Gauges and thought that this was an issue that would be fairly easy to take care of. It turns out that it was about as easy as I expected.... with one exception. The Test Gauge in the upper right corner is configured so that the zero mark represents 30.0 inches Hg. The digital test gauge reads 29.6 inches. The Analog Test Gauge reads4 tick marks below 0 and each tick mark is scaled to represent 0.10 inches Hg. This confirms for me that the proper conversion is divide by 1000. This brings up an issue that does not affect my projects but might affect others: The raw value that is returned in the Token Variable ENGINE1_MANIFOLD_PRESSURE is 0-64K. Since 64K - 65,536 and the conversion factor is 1000, the maximum value that...

    At this point, I have two functioning tachometers with a reasonable appearance. The modifications shown here are the coloured warning arcs, larger display numbers, and the counter balanced pointers. Still having no success with the two pointer tachometer but still trying. - Ivan.

    The idea behind having a digital tachometer was to be able to confirm the correct conversion factor to use in the regular analog gauges. At this point, I have had no success with even the SDK Digital Temperature Gauge, so I decided that there might be another way of finding the same thing. I took one of the tachometers that I had built and reprogramed it so that it would only read the range between 2980 RPM (The new Zero Value) and 3015 RPM. I was pretty sure that the conversion factor I had been using was close enough so that I would be within this range if the actual RPM (as shown by digital gauges) was 3000 RPM. The original conversion factor I had been using was 8.7143 With a digital readout of 3000 RPM, my modified analog gauge gave a reading of 3009 RPM.

    The first gauge background I used was generated by a utility I downloaded. It had some serious issues but worked well enough for the quick prototype gauge. The issues which can be seen from the prior series of screenshots were: 1. The BMP that it generated didn't really match the 302x302 BMP that the SDK Fuel gauge used. I rescaled it to match.'= 2. Although I wanted 4 Small Tick marks between each major tick, it would only give me three.

    Hello All, The last couple of days have been quite eventful with my Gauge Project. First of all, getting the SDK Temperature Digital Gauge to compile turned out to be much easier than expected. Commenting out a few entries in "Gauges.h" turned out to be sufficient..... But although the SDK Temperature gauge now compiles it also displays nothing. After having no success with a digital display, I decided to experiment a bit with an analog display of the variables I was interested in. The results there were quite unexpected. I am still trying to make some sense of what I am seeing which doesn't seem to match the documentation and explanations I have been reading.

    Hello Aleatorylamp, Actually we drove home from the beach yesterday. It was a good vacation though the injuries were not so good. My daughter is still on crutches which wasn't such a big deal on a single level apartment, but at home life is a bit more difficult. I am glad she is otherwise healthy and incredibly strong for her size. Anna Honey still has a weak knee, but can navigate the house and even stairs without a cane. Paul Matt's drawings are generally pretty good when they are available, but they are not always correct. Unfortunately for me, his Corsair drawings are not as good and his P-36 drawings have their inaccuracies as well. The Corsair has some shape problems which bother me so I need to use other references. The issues with the P-36 are along the lines of the...

    Hello Aleatorylamp, I thought you were going to change the paint scheme to something other than"909"? Regarding 2D Seat Backs, there should be no great difference in visibility between 2D and 3D. Do you happen to know what the real seats looked like? Is there a "walk around" for the AT-9 at the Air Force Museum? - Ivan.

    Hello Papingo, I almost never thoroughly combat test the aeroplanes that I build other than to confirm the alignment of the guns. You SHOULD be able to kill the 109E Trop with any of the A6M Fighters. Actually the 109E and the A6M have pretty equal firepower. I will have to try it when I get back hope. I am currently on holiday in Virginia Beach which is most of a day's driving from home. It SHOLD be shorter drive but vacation traffic makes it much longer. I have never tried to do anything with double sized aircraft with Microsoft's Magic Scaling. I always thought those huge aircraft were way too easily to shoot. I have never even experimented with when they double size and when they do not. Should be getting back home in a couple days and will continue with the gauges...

    Hello All, I made a few attempts at using a proper scaling variable derived from a token variable in the simulator. So far nothing has quite gotten the right results. I am on vacation down in Virginia Beach, so my tools are a bit more limited than usual, but I still have my laptop. I thought it might be useful to see exactly how far off I was in guessing at the scaling multiplier that I was hard coding into the gauge so I decided to try to convert the SDK.Temperature gauge into a Digital Tachometer. The first attempt at compiling simply failed. Apparently the SDK has conflicts even with a MSVC compiler.

    Hello Aleatorylamp, Exchanging the 3D seat backs for 2D should not require any differences in glue. The substitution of Structures for Components for the Retracted Wheels should not make any difference other than freeing two Components and spending a few more Parts. I wish I could put something together to demonstrate but my tools are very limited right now because I am on vacation down in Virginia Beach. - Ivan.

    Sorry, Guys/ My pictures are all from the original CFS. They were a response to what I saw as reminiscing. I don't actually fly CFS3 much any more. My comments thus far have been more about the real aircraft and are an attempt to present data that might be useful for builds regardless of the simulator involved. - Ivan.

    Hello HouseHobbit, I also have been involved with the various versions of CFS since very near the beginning. CFS was the first Combat simulator that I found that had enough detail in the game for good suspension of disbelief in my opinion. The problem for me was that many of the aircraft available when I started were either very poor in graphics or very poor in flight modelling. I thought I could do better and started first with flight modelling. After a while, I wanted to prove that a good model could be built with the most common tools and haven't stopped yet. Pity you do not fly CFS any more. I think you would enjoy some of the aeroplanes I have built. Hopefully this is not too far off topic for this thread, but since we are discussing P-40s, I have what I believe to be a...

    Hello Papingo, Hope your skin issue gets fixed soon and you get to go back home. Your understanding of gauges and mine is a bit different. I believe the ".gau" fie is the DLL and the Panel.cfg file only specifies which DLLs to call. The panel.cfg file is a simple text file and can be edited by any reasonable text editor. My need for building custom gauges is mostly because I just want to know how to do it and I like including either stock files or stuff I built myself into released aircraft. I am sure there are better panels than I am likely to build. The need for building gauges at this point is because there are no stock CFS or FS98 multi-engine gauges that will work well enough for me.

    Hello All, Here are links to information supporting my argument that the aircraft used by the AVG were actually in the P-40C production range. A export production and not lend-lease aircraft, they would not have had a USAAF serial number so it was actually the Curtiss Construction numbers I was describing. Curtiss P-40B production. Note the British Serial Number Ranges http://www.p40warhawk.com/Variants/P-40B.htm Curtiss P-40C production. Note again the British Serial Number Ranges http://www.p40warhawk.com/Variants/P-40C.htm

    Hello All, I have actually had some success with programming a Tachometer for CFS. The test subject is a B-25 Mitchell, and unfortunately I have had to hard code the 2600 RPM Maximum. In theory, it should be self calculating but I have not figured out how to do that yet. Here is what it looks like. The hole in the center of the pointer is so that I can tweak the alignment of the indicatory on the gauge face. I am finding that the values which SHOULD center the gauges alignment is very close but is not precise.
