C-47 from Manfred Jahn and team

Please note the sounds between 2:15 and 2:48 in this C-47 takeoff paying particular attention to the "WOWWwwwwwwOWwwwwwwOWwwwww" howling sound caused by the props being ever so slightly out of sync:

As is the case with most of the old radial-engine planes, the prop sounds on takeoff are louder than the engine sounds, and at cruise they are at least AS loud as the engine sounds. Since the C-47/DC-3 did not have prop synchronizers, this sound was not only common, I think it was ubiquitous- I have never experienced a Dakota takeoff that did NOT feature this glorious sound. In my personal experience, this hypnotic "wowwowwowwowwowwowwowwoww" drone continues throughout every flight unless the pilots take particular pains to precisely sync up the props, which is not only very fiddly to do, but requires "retouching" every few minutes... and that's usually more trouble than it's worth. As a passenger in many DC-3s, I have never experienced a more sleep-inducing sound than this soothing wowowowow drone.

I have Tufun's magnificent sound package, but wish it simulated this typical out-of-sync wowow sound. Does anyone know if there is a sound package as good as Tufun's but with the added feature of the out-of-sync wowing? It wouldn't have to try to follow the actual prop RPMs, especially since I think most of us fly with throttle and prop controls set to combine all engines/props into the single control.

Thanks! Very interesting video.
 
Thanks for confirming, Oleg, but I need Milo's and Hoggydog's confirmation, too, as they are the ones who reported the issue. The problem is, do what I want, I cannot replicate the issue here.

To explain one point, the reason for trying to open panels Shift-1 and Shift-5, and possibly to cycle through the VC, is to reset initialization after encountering some odd behavior, usually after loading a saved flight I guess. Nothing gets displayed on screen when you open these panels, the idea is to trigger a reset of variables in main.xml and keys.xml (see panel.cfg). If you have no current problems, the test is redundant, of course.

Miloguy: To change weights, try the Shift-2 Status window on the ground with engines shut down, parking brake set etc. You can change individual settings or pick from a range of typical weight configs there. To get a true cargo configuration you could change values in aircraft.cfg, but I wouldn't advise it because the control system of the C-47 accesses and depends on the current values and will in all likelihood lose functionality if they are changed. As for adding extra fuel, I don't think I understand the question.

Edit. A slightly more detailed tip concerning the above. Aircraft on ground. Engines OUT. Parking brake SET. Open Shift-2 window. Repeatedly mouse-click on "Total Fuel" for a menu of fuel loads. Same on "Total Payload" for a menu of weight loads. Done.

(Actually, that info is in the readme notes in the plane's root folder.)

And so my report. Flight was created. The parking in airfield, on one of gates. By default, the plane appeared with the started motors. Mode -- VC, position -- pilot. I put on parking brakes, I switched off motors, I switched off battary. Chocks appeared. After that in I made changes to settings of the plane: I released fuel tanks, swith off tublers of fuel tanks. After that save the flight and I reset it. Fuel tanks of the plane remained empty, toggle-switches of fuel tanks remained switched off. After that closed flight and new flight was created from the same airfield, same time and with the same plane. The plane on the parking appeared with the started motors, as well as it is necessary for a default. Once again I loaded the kept flight and I received again the plane with the disconnected and empty tanks, with the established chocks. I confirm, everything works without errors.

Pressing of the left button of a mouse decreases, pressing right, increases the current value. Thus, if to change the weight or volume of fuel, gross weight "on the fly" doesn't change. It can change if to change any parameter of "Total Payload".
 
thanks guys for trying

it doesn't seem to happen (wheel chocks) all the time
just randomly

I only use the VC mode

I also only use VC.
In order to block of wheels appeared on the model, it is necessary to perform two required conditions: the plane should be on the parking brake and the battery must be turned off.
Try to make the points.
a. Turn off the engine.
b. Put "douglas" parking brake.
c. Turn off the battery.
d. Switch to an external camera. Chocks must be in place.

If you turn on battery power or ground сhocks disappear.
 
So, to recapitulate, weights can be changed, doors and steps can be made to work, chocks, too, except for certain occasions, which Milo says are "random".

On this issue I prefer to think we just cannot put the finger on the precise condition that triggers that incorrect showing of the chocks and make it replicable for all. Once we know when and why we are likely to do something sensible about it, and it won't be deleting them.

As Wittgenstein said, the way for the fly to get out of the bottle is to show it the way it came in.

Meanwhile I'll be incommunicado for vacation, or possibly longer because to be perfectly honest it is a bit of a waste of time to have me retest the plane only to quote the readme here. No offence ...

Manfred, enjoy your vacation.

Your comment.. "Meanwhile I'll be incommunicado for vacation, or possibly longer because to be perfectly honest it is a bit of a waste of time to have me retest the plane only to quote the readme here. No offence ..."

You are so right!! One of the most respected developers, Pete Dowson, from FSuipc, also, & rightly so, gets so upset when people do not read the Readme's.

Hi HoggyDog, I watched the vid and listened to the takeoff... I know that sound, I've been in 2 DC-3/C-47s in real life and heard that sound, it is very distinctive.
Not only did I hear that sound, I felt it go right through my whole body, vibrating, and felt the pull as the props pulled into the air. Man oh man, what a wonderful old plane. Once up in the air, the noise quietened down into a low rumble as it settled into cruise. Much quieter than the modern turboprops that I've been in.
 
I just want to say that this package has given me a tremendous amount of simming pleasure over the past few years. There's just something about this big old taildraggers with those beautiful radial engines.
 
Well said griphos

I agree 100% and still looking forward to the proposed updates. Hint.....
I have only 5-6 hours logged in a real C-47 (right seat, of course) but loved every minute of it.
Also flew a ton of hours in it as a passenger and even that was pleasant.
 
Nice! When you told me about this project I didn't really realise how complex it actually was. But really a nice life for something which was already a wreck before it hit the bridge on the highway.

Cheers,

Just when you thought everything had been said about the DC-3...

This original, 1/20 scale trade-show model was a proposal by Fokker, dated about 1935. Fokker was the exclusive European importer for Douglas Aircraft at the time, and this conversion was made available to countries who might want to make instant bombers out of their growing fleets of commercial DC-3 airliners.

In addition to bomb bay doors behind the wing box, the DC-3 bomber featured a couple of pillbox machine gun turrets on the roof and a bombardier/gunner blister under the cockpit (the model's nose gun is long lost, but the other two survived). DC-3 passenger windows were not covered up, so one can assume these aircraft could be un-converted and returned to commercial service, at the end of the conflict.

The model is all-metal, with retractable gear, and features the signature plate of Joost van Pelt, master model maker for Anthony Fokker. So there were apparently high hopes for this idea at the time, which sounded reasonably good, given the reliability of the airframe.





Now, this could be great to have!!
 
Great airplane, 2 questions... Is it possible to replace the 530 and 430 gps units ith RealityXP? I replaced the lines in the panel.cfg but they do not appear.

And I'm having trouble starting the engines at high altitudes. Any tips for getting them running at 8000+ feet? Thanks

Is your mixture set at full rich, maybe? This will prevent the engines from starting. Even if they do start, you barely have enough power to lift off. I'd try to set them at a lean position.
