Warthog Advice, Please?


Uncle Pete

Recommended Posts

I need a little help here, lads.... I'm in the process of beating a confession out of Italeri's 1/72 A10 and it comes with this little fella for the leading edge....

 

A10 1

 

... I'm assuming it's slats and should be fitted thusly....

 

A10 3

 

Unfortunately there's no post-installation picture in the instructions and the box art seems to show them closed (and if installed closed, I'd have to cut off those little pegs).  I've poked around on the internet but can't seem to find any pictures of them open.  Before I get the glue out and the vicar says, "Till death do you part," any insight would be much appreciated.

No expert but there fixed in place and don’t move so don’t remove the tabs that hold them proud of the main wing, also in the photo you show above it looks like you have them the wrong way round, the thicker leading edge should be facing forward.

Yep! Muzz is correct. I have attached a link to some A-10 photos that show the fixed slat, as well as some that are just pretty neat! Love them Hawgs!

:facepalm:  I was afraid somebody would say that!  Yesterday I realised I'd painted the ailerons upside down.  Up until that point the build had been going deceptively smoothly.

Appreciate it but for some reason it says the link won't open in West London.  (Actually, it wasn't quite that specific but you get the idea!)

Cheers.  I'd shoved Warthog and A10 into the search thingy but evidently that one didn't pop out high enough on the list to bring itself to my attention (or, more likely, I was asleep at the switch again) and Google Images wouldn't give me anything close enough or from the right angle to show it up.

 

 

Thanks, lads, somebody always comes through on this site.  It was just a matter of finding a pic from the correct angle .  Onward and upward as soon as I've finished stripping and reapplying paint to the little devils.  My "I gotta buy this bloke a pint" list is getting longer!  🍺

Hi,

Some pics I found at http://www.primeportal.net/hangar/a-10_home.htm

I may be mistaken but I believe they do in fact move up and down depending on angle of attack.

Tonka- outstanding photos! Better than the ones in my link! I have filed these puppies away for future reference- thanks so much for the post!

 

Uncle Pete- Sorry you couldn't open my link; not sure what's going on there, as my other modeling cohorts said it opened OK for them...gotta love cyberspace, right?

They are fixed. They are fitted to alleviate the problem of ingesting gun gases into the engines.

Any further questions, we have our own pet Hawg. They are not painted red either. Airframe colours.

These pictures would seem to indicate that they move. Please correct me if I am mistaken.:shrug:

The engine position does have its liabilities. At high angles of attack, the wing can block airflow to the engines, and so a short leading-edge slat was installed between the fuselage and the main gear fairings, the slat opening automatically under hydraulic control at high angles of attack. The YA-10As uncovered the problem, and were fitted with fixed slot surfaces as an interim fix. Apparently the use of the leading-edge slats introduced another drawback in turn, in that it reduced indications to the pilot that the aircraft was going into a stall. A small strip was attached to the leading edge of each wing to ensure that the descent into a stall wasn't so abrupt.

Interesting exchange. So we have a combination of AOA stall and gun gas. Surprised the guy was suspicious of the gun gas. The early Hunters were the same with the ADEN gases. Not cured until the Mk6 with the Avon engine mated to the Sapphire compressor stage.

Also correct about changing the charge to alleviate the gas problems.

The guy was half right about gun barrel temp with a long burst. If you hold the trigger down and exhaust all the ammo in one burst, the recoil slows the aircraft to such an extent that it stalls.

See post #10. We have one in our museum. Camera angles can be misleading.

 

Here is a link to a video on the A-10. IT is a good video but if you want to, skip to 2:45 through 2:55  and 15:50 through 16:00 to see the slats in action. it is really quick.
