kinver, how would I sign up for one of these?

You would PM me, or kinver with all your contact details, and we would forward them to the boss,

Thanks, I have sent you a PM with the necessary details

What would the recommended petrol powerplant for this one be? Is there a radial engine out there that would fit in the cowl with the extra little bit of power to make simple aerobatics like hammerheads, teardrops, and humpty bumps look good?

and i have replied,     engine?  any 30-40cc that will fit a 9.5"diameter cowl,  depth should be no problem,  there is lots of it,   

Anybody started an assembly log for the La-7 yet?

I finished my LA7 last week. Sorry no build thread but I will try to take some photos, and for any of you building one feel free to post your questions here and I will be happy to help.

 I fitted an evolution 40 cc petrol engine. I can see its going to be overpowered so I will be using a fair bit of throttle and speed management.  It fitted pretty well with only a small part of the cylinder head/ plug cap sticking out and the exhaust tubes.  I am now waiting for some extra weathering work to be done and that should really bring it to life, then hopefully if the weather clears I can get some flights logged.

Hi Ali,

What spinner did you use in the end?

Mud 

One that I had kicking about. too small, wrong colour and wrong shape. Apart from that its spot on.

Anybody have any ideas on what electric motor to strap on to the La-7.

I was thinking along the lines of a AXI 5330-24

Just picked Ali's Lavochin up today to do a weathering job on... if Ali doesn't mind will post some pics of before and after.

Wayne

Thanks Wayne
 Please go ahead and post!

Cheers Ali will do that then...

One thing looking at all my Ref material is how void of surface detail the real thing was / is and consequently how difficult it is to find any decent pics of one that has any weathering at all...

Will have my work cut out with this and trying to do something with those huge wings.    
Sure I will come up with something though/

Wayne

I am looking forward to it.
 

Dont forget,  the LA-7 was an all wooden aircraft,  dont start rivet detailing the wings!!         i am asuming the wings would have been ply covered,   these would have been nailed or glued on, or both,     apart from gun hatches etc,  there would not have been much detail,     i would keep it to a general dirty wash, and exhaust stains,      cant see there being much else,

do a google images search, there is about 20+pages

 Cheers Al, Yep thanks ...I knew the Fuz was wood up to the cockpit but didn't realise the wings were as well.... I have loads of ref pics and books as well just didn't bother to read about how she  was constructed ...Cheers though...

Wayne

I though the big change with the LA-7 was that it had metal wings as opposed to the all wood construction of the LA-5....?

Here's a link to some walkaround photos of an LA-7 in a museum in Russia:

http://scalemodels.ru/modules/photo/viewcat_cid_142.html

Brilliant site loads of useful information

Indeed Martin some great shots and lots of info...

Thats one of my ref sources I already have thanks BB-Q but it does confirm what Al was saying its all wood apart from the cockpit fwd. You can see on the wing shots where the covering and paint has crazed... Don't you just love the quality of work though?  (Not)

Wayne

God what an old crate that one is? I do like the plane though.

I did some measuring last night.....
  The diameter of the cowl opening is 148mm.

Looking at the Dave Anderson plans and scaling them to the correct size for the 148mm cowl diameter it looks like  the correct diameter will be 111 mm.  As usual we are between standard sizes!  I will most likely go for the 115mm (4.5") spinner.

Now the shape........ Again it is neither a parbolic  nor standard.....  maybe parabolic will look the least wrong.


i want to make an recommendation to the designers/ manufacturers of these great scale kits.....

it cannot be that much more expensive to make these in equal quantities to the kits. 
Please include a correct size and shaped spinners with all the models that require them.  If somebody want to use something different then it is their choice.

Here are some pics of Ali's LA-7 that I am about to start weathering...

I must admit, I do like the look of this model.
It look as if it is doing 200mph just sitting on the ground.

Hi

I am interested in the LA-7. Does anybody know the next delivery from overseas?

At yt international the LA-7 is sold out.

regards

Mirco

Please contact your stockist, lindinger, for advice on this   we do not control their dielivery times, only our own, and thats difficult enough!!

Due to a customer dropping out of the pre booking we do have 1 La7 left, first come first served.

Sym.

Warbirdman,

would you mind sharing some pictures and tips on your weathering job as jou progress.
I will be starting on mine soon....

regards

Yes sure... Progress has stalled at the Moment while I finish off the Hurricane but did start it last week..

As I have said on the TY Site forum, an all wooden plane is going to be diff to do but ..hey ho..

I started on the only metal area on the wings  the aluminium panel where the two sections of wing were joined..

To do this I just draw the area out with a dark grey Derwent Pencil.
I then scooped out the thick bit of the paint out of some Humbrol Aluminium... ie I did not stir it!..
Put this on to a piece of plastic then with a cloth wrapped into a tiny ball dipped it into the paint a little..I say a little because you are not after a lot of paint on the cloth.

Then using a piece of very thin plastic I used this as a guide along the hard edge I wanted to form.

I then brushed , like polishing but in one direction off the plastic and onto the area I want to add the paint.  This has the effect of making the paint look worn down.

I will try and post some pics on how I do it later but here are the results so far...

Hi Wayne,
 Any updates?   I have just been looking on RCU and there is a chap doing the same as you are in the states that got me all fired up again
 Regards Al

That is amazing Wayne how a little effort produces something that leaps out of the photograph into 3 dimensions.

I would swear you had a metal panel screwed to that wing...

At the moment I am busy finishing off the Hurri but thats nearly finished in the next week.

 Will do some more on the LA-7 this weekend now that I can get the Cowl and Canopy off.

I won't be going to the lengths that the guy in the RCU site is going to with the cockpit..just weathering...

I have started to paint the Dummy radial though and cut the mask for the Star, one on top of the wing and on opposite side on the underside. Not standard but adds interest to an otherwise dull wing.

Wayne

The rest of Ali's LA7 can be seen in

WARBIRD MAN WAYNES CUSTOMISING HANG OUT

Anyone else got a LA-7 ?   lets see it !   

Cheers
Wayne

Yep! I have an LA7 thats almost finished..

HaHAhA       Nice one... Thats hardly an ARFT now is it Ali ?! Smart Model though... funny how you could mistake the LA-7 for being an all Metal plane from these pics... Excellent work though...
