bobster Posted October 29 Share Posted October 29 My question is this, are the slats on the La-5 open when on the ground? in other words, do they work as on other WW II AC, being deployed spontaneously when wing is in a high angle of attack when flying, and then open on the ground ? All the photos (except for one or two) show closed slats on the ground. Could they be manually closed when on the ground? How should this be modeled on a resting La-5?...Bob.

TBC Posted October 31 Share Posted October 31 (edited) Yes, the slats can be open when on the ground, but the vast majority of photos show them retracted. They were automatic and deployed based on aerodynamic forces. Something to keep in mind if you are going to build a model with them deployed, is that the slats did not move forward in a straight line like, for instance, a Bf-109. The actuating arms of the slats were bent so that the slats moved in an arc (forward and then outboard) towards the wingtip, which resulted in the outboard edge of each slat overlapping the leading edge of the wing outboard of the slat bay. For now, here is a photo of deployed slats. When I get more time I will post images showing to good effect how they moved. Edit: Something I forgot to mention. If you magnify the image below you'll see that there is also a vertical displacement. You can see that the outboard edge of the slat is sitting above the upper surface of the wing.

bobster Posted November 1 Author Share Posted November 1 Thanks for your response, Jari. That is an excellent reference that you sent. I am beginning a Craftworks resin kit, and it has retracted slats, but having them open is much more dynamic looking. I have not seen slats that wrap around to the undersurface as these. I think I will open them on my model. Thanks again for your help...from Bob. Isar 30/07 1 Link to comment Share on other sites More sharing options...
Dpgsbody55 Posted November 2 Share Posted November 2 Some great information here, so thanks for posting. All we need now is a decent injection molded kit which I would likely buy, especially if ICM did one. However, I'm guessing anything Russian might not be the flavour du jour with them right now....

Cheers, Michael I don't know about that. They just put out a YAK-9T about a year and a half ago [ a very nice kit I might add]. I wouldn't count them out just yet.

TBC Posted November 2 Share Posted November 2 (edited) A couple more images. The image below is a screen capture from a movie. It is just one in a series of screen captures that, when cycled through, follows the slat through extension and retraction.

True enough, and I have one of their Polikarpovs as well as a YaK-9, but they're a couple of years old now. ICM have done nothing new in 1/32 releases although a Hs-123 is due "soon". I'm guessing they're struggling. ICM is missed, and I hope the situation improves, and not just from a modelling perspective. From a purely selfish perspective, I want to see them back to releasing a couple of new LSP models each year as the kits are first rate.

bobster Posted Monday at 04:36 PM Author Share Posted Monday at 04:36 PM OK. So these slats work much how I feel some days, they go "down and out." Thanks for all the informative responses...Bob. CRAZY IVAN5 1 Link to comment Share on other sites More sharing options...

I've learned so, SO much since landing here in the early/mid 00s. I can't even count the times I've had something in my mind I just could not wrap my head around, only to ask the question and get an almost immediate well thought out response, usually with an idea I had never thought of.
