Reflective skins now dull and non reflective problem
rel4y replied to gdotts's topic in DCS: P-51D Mustang
Your skins are amazing Reflected! Keep up the awesome work! -
I am pretty sure you can replace the thumbstick with an ALPS RKJXV1220/RKJXV1224 or any clone from ebay. You would have to desolder the pins of the old one and solder the new one in place. If you are not confident doing it yourself you could also send the part to me and I swap it out for you. But give it a try first, you already did the Bodnar conversion. :)

Hey kojdog, Awesome to hear everything is working well for you! My slew sensor uses the same type of analog microstick as are used in Playstation 4 or Xbox controllers. Theoretically it can replace the thumbstick directly and interface with the CH mainboard, but you would have to cut out a part of the PCB. The CH hatswitches and microstick on the thumb panel sit on top of a PCB and the distance between the black plastic cover and the PCB is simply too small for a PS4 Microstick. If you cut the PCB and solder the cables derectly to the Microstick it is possible. On the indexfinger position it is a simple swap, but you still have to connect it to the CH mainboard somehow. You could swap the original Microstick for a four way (from the index position) and insert the slew sensor in the index position. Again, not sure if its worth the hassle. I will do a new 12 Bit PCB for the CH Throttle eventually which will make it easy. Just right now I have higher priorities. :) Btw, big thanks to the community! I sold all the sensors I made and now have recouped my initial investments and had enough money over for a Creality Ender 3. The printer arrived today and I hope I can start making 3D prints in good quality soon. This is going to be put on a first big test for prototypes of my MFG Crosswind combat pedals. These are as close as I can get to a F-16C Block 50 pedal without 3D scanning. A few details need to be reworked, but they are almost done and will soon go out to beta testers!

Ok, I think I got it. Next is a 3D print to check how they feel. I am pretty hyped! :D

Wrong Pin (and no calibration mode). Arduino Pro Micro doesnt have an A0 pin. Check this scheme here and read the GitHub page about MMJoy, it explains all the basics! :) https://github.com/MMjoy/mmjoy_en/wiki/Connecting-basic-inputs-and-setting-up-software

Thats why I said check the COM port during reset in bootloader mode. ;) The Arduino bootloader has a different COM port than normal EEPROM operation. Windows only recognizes devices that have at least one axis. So set up one axis in MMJoy and that message will go away.
-
There is like a plastic shim underneath the lever that exerts friction onto the big black throttle axle. This shim likes to slip out and upwards of its correct seating, so check that. If thats not the case and the thing is just too worn out, glue or stick another (~1mm) shim underneath that plastic part and you should have sufficient friction again.
-
Are you sure you are using the right COM port? Which Arduino do you have? (Pro Micro 5V?) Put the Arduino into bootloader mode (reset to ground) and check in the device manager under COM ports which port it is. You can get to device manager by typing "compmgmt.msc" into the run box.

Really interested in that book, thanks for the hint! Not only G-14 AS, but also all ASB, ASC, DB and DC variants were running the larger DB603 supercharger. In the September 44 K-4 manual it states normal 50h intervals for engine inspections and with C-3 fuel the engine is not time limited in any way at 1.8 ata. I hear lots of anecdotal claims that MW50 would burn out the engines really fast, but I dont see a scientific reason behind it. The ADI actually causes lower combustion temperatures as I have said several times now. As the water is evaporated during combustion it turns into steam and soaks up tremendous amounts of heat, while the steam causes a good but safe (because late) increase in cylinder pressure. Then it basically steam cleans the cylinder and exits through the exhaust while also having decreased the exhaust temps. In this doc from 20.01.45 (http://www.kurfurst.org/Engine/Boostclearances/DB_Niederschrift6730_DB605DBDC_20-1-45.pdf), Dr. Scherenberg from Daimler Benz explains that "troubles with white flame with subsequent burned cylinder can be mostly attributed to inferior fuel quality". And I think this is really where the crux lies. Basically what happened was that detonation occured due to too low octane and contaminated fuel and completely wrecked the cylinders. But that is no effect that could be attributed to ADI. ADI actually is supposed to prevent exactly this damage from happening. I say it again, I very much doubt that engines were wrecked due to prlonged use of ADI. Btw DB responded to this problem by retarding the ignition point and decrease knocking of the engine which causes a loss of 50 HP at Sondernotleistung. Also of note is, that this document talks about that on the eastern front mainly B-4 fuel was used so to this front it is important to give out the information about ignition retardation as soon as possible. Which implies that on the western front C-3 fuel was in frequent use. Considering the overall number of LW aircraft at that point it probably werent that many. :smilewink:
-
Why dont you have a look at Debolestis Shapeways shop. He sells replacement parts for exactly this case. Many people have bought these replacement parts and they work. I am using one as well (I made it myself). Really is an easy fix.
-
OK, thats another way to do it. I didnt know that you could take out the shaft that easily. I actually planned to mount it to the small plate the pedals are attached to, just with screws going in from the back and tap the threads into the aluminium pedals. I guess it all depends on the height of the foot rests and what is the most comfortable in the end. :)
-
Well, I would obviously make a prototype and send it to him. I am not new to engineering stuff. :P However, with accurate measurements a simple one piece pedal has a high likelyood of being perfect the first time. That being said I already organized someone whos shipping his pedals to me, so dont worry.
-
With all due respect, I highly doubt that Stiegler is correct and or has experienced a failure due to prolonged use of ADI. Id like to hear one scientifically sound reason why prolonged MW50 use at rated boosts would damage the engine beyond normal. This is completely irrational to me. If you could run the the DB605 on C3 fuel without limit at 1,8 ata please explain to me why it shouldnt on B4 + ADI. There is simply no way that if the same engine that could tolerate 1,98 ata and even 2,3 ata at the Daimler Benz teststand, cooling would be insufficient at 1,8 ata + ADI which actually makes the engine run cooler. You have to change ignition timings, but thats it. From an engineering pov the only engine part that is stressed beyond normal is the supercharger, because water droplets will cause damage at these really high rpms. The only other downside I can think of is corrosion through water, thats why there is always a fraction of oil added.

I plan to make a small batch out of airgraft grade aluminium. But I need your guys help, I dont have the Crosswinds and I need accurate dimensions. If anybody could help me with the accurate dimensions of the pedal lever, angle, screw holes, threads etc, I could be done in no time.
-
Basically, for your use there are none. 4021 are a bit more modern and also a little more expensive. The 74HC types are from the 60s or 70s mostly.
-
74HC165 are for inputs. But you cant use the breakout boards from ebay, they require significant rework on their schematic.

Anybody interested in F-16 combat rudder pedals for eg... MFG Crosswinds?
-
I finished the CH Fighterstick mod PCB. This PCB will convert a CH Combatstick into a Fighterstick & more. The bottom header pins will connect directly to a shift register PCB, which I will do next. It is also compatible with a superb quality Knitter MPS103F as pickle button, at least the cutout is there. :smilewink:
-
Just yesterday I found a crap ton of docs on the real dimension on F-16 parts. Just updated the CH Slew Sensor, it is now completely to spec of the real deal (although I was very close). :music_whistling: Also good news on the STM32 front. I played around with several HID enabled firmwares of these little 32 Bit ARM MCUs and I may have found a way to make them TARGET compatible. That would make it possible to install a replacement mainboard for all older joysticks with 1000Hz updaterate (standard Cougar has 100Hz eg), 14 Bit axis resolution, 4021 shift reg support and TARGET compatability (maybe even running on FreeRTOS instead of last decade Arduino loops). That would be like the holy grail of flight sim gear.. :joystick:

Thank you FoxHoundcn! Great job!

New hall effect sensor kit for the Cougar Throttle without the USB standalone adapter:

Is it a video your talking about, where can it be found? But why should Frank Walkers analysis disagree? He basically ran WEP with ADI on his R2800 testengine for 100h straight on a regular basis. PW used intercoolers in their engines and injected the MW or EW into or after the carb while the germans injected into the supercharger. That should lead too a smaller water charge cooling effect in the PW engine since the air is already cooled and evaporation is decreased. Internal combustion effects are unchanged even though the DB uses DI. The germans increased the oil cooling capacity on these late ADI engines and encountered no cylinder head overheat which I think was a problem with the R2800. However, the basic ADI effects stay the same on both systems: less detonation, charge cooling, lower combustion temp, higher mean pressure, lower exhaust temp, less carbon buildup.

Firstly I think I found the problem with the CH pots. The decoupling caps I am using are of the wrong value, I ordered 100nF caps but got 10nF. So as decoupling caps these are pretty much useless and I might have been using none at all... Decoupling caps are basically for smoothing out the power supply and reducing noise. Before I realized this, I had already redesigned the PCB and possibly improved grounding a bit, so newer sensors will have a rev 1.1 PCB. Secondly, I received the Shapeways shipment today, but I have to say tolerances this time were abysmal.. I contacted Shapeways, lets see how it turns out. Anyway, here are a few new toys. CH sensors for Combatstick, Fighterstick, Pro Pedals and Yoke: Saitek sensors for Pro Flight Pedals. However, these need to be redesigned because currently they are just way too hard to assemble and some dimensions are not quite right yet. Please ignore all the dirt, once the sensors are ready I will clean them thoroughly. Next, CH hats and slew. I absolutely love the feel of the CMS and DMS hats and the slew sensor. The slew sensor case and hatswitch case need a bit of work as it is a pretty loose fit currently, but it might as well be that Shapeways botched the dimensions this time.. The new PCB for Combatstick to Fighterstick conversion is getting along good, but I have only so much spare time per day. :joystick: Finally, I can now offer Allegro 1324 based hall sensors for the Cougar Throttle (for those that do not want to convert their Cougar Throttle to USB standalone and use my digital 14 Bit sensor). I tested this setup today and it works as expected, calibration is easy too. Price will probably be 15€ with cable as PnP, but I cant ship before next week. :)

The test stand runs of the DB605 DB/DC showed that the engine could run on MW50 for 40 mins straight with lower stress on the engine than without. The cooling requirements with MW50 injection at 1,8 ata were pretty much the same as without it at 1,45 ata. I currently cant find the document, but I found one for the DB605A vs AM engine. This chart compares the cooling of 1,3 ata vs MW50 1,7 ata. The K-4 had increased oil and water cooling capacity over the G models btw. https://forums.eagle.ru/attachment.php?attachmentid=108157&d=1417348418 Btw: I see no reason why it should be any different for the Dora if the cooling capacity was enough for standard max boost. MW50 will increase detonation resistance and decrease combustion and exhaust temperature. There is basically no negatives except the weight of the injection system and MW50 itself.

Been following this project for a while. Awesome stuff, keep it up guys! Why dont you have a look at the Hempstick firmware? It is open source and perfectly suited I think. It runs on FreeRTOS and is much superior to the usual ATmel Arduino loop based stuff. :) http://hempstick.org/The_Official_Hempstick_Site/Welcome.html Cheers
