Hi Prekin,


Yup, well a simple conversion. I will leave off the rear radiator intake and of course the repaint.


I may do the cowl intakes later.

It will be different than the standard ESM and yet be an easy change for a workhorse flyer.

Hey Guys,

I received my Gene Barton Spinner yesterday and I'm really happy !!

It's really close to the profile shown on this thread earlier and just over 4.5inches in diameter. It fills the cowl nicely leaving about 3/4 of and inch gap all the way around. I don't think I'd want to go any larger.

Here are a couple of pics. Plus a sneak peek at my newly stickered P3 F-16... But that's another subject.

Joespeeder Was that spinner a special order or one he has listed on his sight?

SU-31 Flyer,

I guess you'd call it a special order?

I didn't see it on his site so I dropped him an email and he said he had this spinner that would work.

I really like what he came up with.

I have HS485 in ESM Ki84 and they are fine
577s may do the job as well, but I would go for something slightly more powerful

I bought one old ESM La-7. The flaps are with the HS-485 and the airlerons are with graupner 577. I think that I will change them each other.

Thanks Joespeeder!

I don't know those servos tork but the flaps need more power to hold than ailerons do.

Why the flaps need more power than the ailerons? The speed is lower so the air drift is smaller than during the fullspeed roll around the lenghtways axis.

Ailerons still only roll the plane. Flaps have to left it on landing to slow it.

Just took the canopy out of the box, and it is cracked right down the side about 4 inches ! 

I am going to call to get another, but this stuff is real brittle, cannot see it lasting, anyone find a better solution ?

Flaps have to slow it? It think, that you mean aerodynamic brakes, but flaps have to make bigger lift, when the airplane going on low speed.
If you open the flaps the contrast of the velocity between the upper and lower part of the profile is bigger, so the lift will be bigger. In the real airplane you musn´t open flaps when you are fast, because you can brake the flaps. This is the reason, why we can see the opened flaps only during the landing,take-off or slow fly-by.
If you want to brake airplane you should flaps on the upper part of the wing for example gliders. They have brakes in the third of the depth of the wing. Please, imagine the polar and the lift curve of the wing.
Flaps have bigger coefficient of the LIFT than coefficient of the DRIFT.
If you want I can write you the formula for the lift force and drift force, it is pretty easy. [sm=thumbup.gif]

I was lucky enough to have John Laird from our club bring out his video camera and cature my LA-7, he was also able to capture my P-47 and I posted that on Hanger 9 30 CC page if you are interested.

I have posted other still pictures of the plane earlier and I really must say I love the Seirra gear I installed and converted to Electric,

I hope you enjoy the video.

Hi AZThud,

Great vid !

You nailed the landing !! Really nice.


I've been working on mine. Last weekend I drew some panel lines, then taped them off, sprayed the AMT-12 camo. I removed the tape from the red stars and found a gray that didn't match the others to cover them up. I sprayed them over but did a intentionally bad job leaving some of the red to show through just slightly.

I have some pics from before the stars were sprayed.


Enjoy.

Joe

The question about the fuel fill is easy. I made small door on my Zero and I also going to do it on my La-7

Joespeeder,

Really looking forward to seeing it all done up in its captive scheme.

I thought about that one myself actually(if I had bought the La), but went for the P39 instead.

Thanks Casey,

I worked a bit on it last night.


I painted the cowl and applied some of the decals on the fuse... Wow!! That really transformed the way it looks. I have to do the stripe on the rear of the fuse and then the wing bottom details.


Then weathering.


Here's a teaser I took with my phone as I walked out this morning.... No lighting or posing. Just a raw shot.

If you put the canopy under a quite hot tap it will soften the material enough to cut it easily. Use a set of curved canopy scissors for the best job.

I did use the hot water and cut with good snips, the crack was there before I got to it, just seems brittle was all, think Ihave it solved though. Thanks !

Hey Guys,


I painted the yellow band on the tail and the stars off the bottom using warbird colors RML blue. I like the miss matching of the blues on the bottom and once I get the German crosses on there it will look really good. I'm thinking I'll do the yellow wing tips on the bottom as shown on the paper model. When I look at the Luftwaffe Archives photo of this plane it looks like you can see a surface change on the bottom of the wing tips and it will help with visualizing what the LA-5 is doing in the air for me.


I'm thinking I'll get both flat and satin clear coats from Lowes to highlight the various paint areas. Russian paint will be flat, German paint will be satin or a mix of satin and flat, and the silver exhaust area will be left the ESM texture. I'll paint in the exhaust with an airbrush and then flat over the exhaust.

Here's the progress this far.


Joe
