Engine On Vought V4U-7 Keeps Shutting Off

[cockyboy]

I recently downloaded the Vought V4U-7 (file name: corsair) from here at FlightSim. When I select it for the aircraft I want to fly, the aircraft loads, and the engine runs for about 6-7 seconds and shuts off. I restart the engine and it shuts off after about 3 seconds. I saw comments somewhere where someone suggested switching the panel with the panel from an aircraft that works. I tried copying the panel from another Vought Corsair that I downloaded and the problem still persists. Just as well, as the panel I tried switching with isn't anywhere near as nice looking or functional as the panel that came with the V4U-7. This is the only aircraft that does this. Anyone have any suggestions on how to fix the problem? Any suggestions would be greatly appreciated. Thanks.

Hi Jim,

It's necessary to keep the throttle up quite a bit or the engine will quit. I'm not aware of any other solution. Also, with this aircraft it's needed to put in 5 degrees of right rudder prior to taking off or it's very hard to avoid crashing.

I've worked extensively on this aircraft and in the Engine Start section of the Checklist I have "Throttle - 15%".

I have that bird too. If you are any more than a couple thousand feet above sea level, like at Reno, say, you need to lean the mixture down fairly quickly to keep the engine alive. Additionally, as SOON as you get in, let it die, then hit CTRL-E to fire it up properly. A switch, and I think it's the magneto switch, isn't on by default on that bird, even if the default plane you start out on does have it ON.

I'll look on mine. I had that problem, and I figgered it out by watching it start the engine with CTRL-E several times, in the VC, with the left and right sub-panels open. It took about 15 times to get it, but if you do that, you'll see some small little thing that isn't normally missing, but get's caught by the auto-start sequence. You just have be very attentive to details as it runs through, cause it's pretty quick, and it's not obvious. It's very small and almost hidden, but it's there.

OH! I think the Generator may be off too, and needs to be on, or maybe the Master. SOME switch isn't on, but CTRL-E turns it on during the startup sequence.

Finally, and this is important, I think that if you run the throttle down all the way, to the lowest it will go, that's the fuel shut-off, so if you hit F1, it will kill the engine. I think. Haven't flown it in a while. but try hitting F3 about 3 or 4 times to see.

As soon as I can, I see what it takes for certain, but those things I mentioned are all important.

By the way, the original Alpha-Bleu Ciel Corsair is a great bird. Flies like a dream, although, like the real Corsair, it has it's quirks! Beware :D

Hi again,

 

I'm not certain we have the same aircraft and mine ended up being a compilation of several versions of the Corsair. I'm including a picture of my VC. The Ignition switch in the lower left will start or restart the engine if there is sufficient throttle to keep the engine running. I don't think that reflects reality but that's the way it is.

 

 

Here's a portion of my modified Checklist that I use to successfully start the engine. Sorry for things being so spread out; I copied it from an html table. The original checklist was in French and this translation still requires a few edits but using my best guesses it works.

If the zip below is the one, then here is the fix. The '//***' indicate they are the orig values. Save a copy of aircraft cfg before you edit (just in case). I did not fly it (yet). But since it's from 2009, the fix should apply.

I find this one to be right on! corsairf4u7.zip available from either Rikooo or FlyAwaysimulations. Will post a shot!

Hey zippy,

Are you sure that's the right filename? I have that file and it installs with an .exe and I don't want to check it out but I thought it only had French markings on the aircraft.

Filename is correct. It did have French markings but I managed to find the repaint that's installed now. I pulled the filename out of the README that's still in the aircraft folder.

 

I also agree that the throttle needs to be advanced a little at startup to keep the engines running!

[jandjfrench]

Hi zip,

I think we pretty much did the same thing. I think I used the textures from CorsairX.zip which has the Blacksheep texture and a couple of other US markings.

The file corsairf4u7.zip is also over at AvSim. My dad was on a Navy Carrier in 1945 and he sent home pics of him working on these babys. Then is when I got hooked on aviation. I was 5 yrs old then. I could draw (#2 pencil - hehe) a mean looking airplane when I was 10.

Hey Chuck,

Yeah, I've got a pretty fair collection of Corsair files but don't know where most of them came from.

 

See Edit at bottom-------

 

And while I have you on the line I recall you mentioned a failed hard drive and the cost involved in recovering the data from it. Every so often https://www.giveawayoftheday.com/ offers free programs that will allow you to recover it yourself. And as fate would have it I just checked today and there's a section on which you can vote on which program you'd like to see as a giveaway and a data recovery tool is one of the choices. Head on over and vote.

Jim F.

P.S. You only have until 1 AM to vote. That's when the site updates.

 

Edit---Bad news. I just checked and the free tool is for iOS data recovery. But I check GiveAway daily and don't imagine it will be too long before what you need is offered for free.

Hello Again Everyone,

Thanks for all the replies and suggestions. I did try the 'fix' suggested by napamule2, but it didn't change anything. I may have done something wrong, so I think I'll try it again when I can.

Thanks again.

 

Jim

[napamule2]

Jim,

I checked and it seems they made a mistake - they got it backasswards. Here is the correct values to reduce the idle friction so the engine doesn't die on you. Did not check the 'corsairf4u7.zip' yet.

 

For: corsairX.zip : aircraft cfg:

[piston_engine]

idle_rpm_mechanical_efficiency_scalar= 1.000 // 0.65 //*** Original value

idle_rpm_friction_scalar= 0.650 //1.0 //*** Original value

 

JandJ:

I got the Porsche 911 running BETTER than before, so why should I spend $400 (plus shipping both ways) to recover the files. And those 'free' recovery programs mainly go in and (try) to retrieve deleted files. They don't fix Master Boot Record or whatever it is now called for SATA HDrives. I am putting in my will that that HDrive be buried with me, so when I get to the other side ...... er, never mind (hehe).

Well I installed both of the Corsair zips. The cfg needs work on both. But it helps to add as I posted in above 2 posts. You should also add 'differential_braking_scale=0.800' and increase the brake to = '1.000'.

 

So when you go to 'punch it' on takeoff you can use differential braking (2 or 3 taps per second in quick succession) until the tail comes up. Use my head.

 

Now I know why I did not have this bird installed - the prop hides behind clouds. Bugs me enough to delete it right this minute. I made videos with Fraps. Film at 11.

No cloud problem here.

 

 

Say, this wasn't one of those "made you look!" jokes, was it?
