Default Zlin 526

Hi all,

I am just getting started on a 1/5th scale Zlin 526 AS with a span of 83". A few years back, Sig had a very nice 1/6th Zlin, which I built. It came with some excellent documentation and of course I have no idea what became of that stuff, so am wondering if any of you pack rats may have said documention and would be willing to part with it. Other wise I will have to do it the hard way, you know, put some real effort into finding it.

Thanks

Thanks Tailskid,

The item is now closed. It sold for $130. Would not have paid that as I just want the documentation, so will start collecting stuff and see what the various documentation sellers have to offer.

Thanks again,

Bish

Hi

Just as an FYI

Model Airplane news has a set of plans for a ZLIN Z-526AS. Designed by Dick van Mourik. Construction article was in the January 2002 issue. Is 20% Scale. Wingspan is 83 inches, no flaps as is the AS version. Cowl and canopy are available from Traplet Publications Ltd. Are in the US. I am about 2/3 way through framing it up.

Bob Banka has several Photo paks and a 3 view

Hope this help.

Ray

Thanks Ray,

The van Mouric Zlin is the one I am building. Have most everything I need, cowl, belly pan, retracts, canopy,etc. just want to gather as much documentation as I can. Will see what Banta has as well.

Ray,

The thing that probably concerns me the most is the colors. I may be wrong, but when I built the Sig model it seems to me that there was good color documention inclued in the kit. As I remember, I used K&B paints on that model and it finished very well. Not quite sure what I will use this time around.

What are you going to use for power? I have been in contact with Dick van Mouric and he assured me that a 2C .91 (I have an O,S.) will be more than enought power. He says the plane is not fast and is very graceful in flight. I am concerned about the nose over problem that required me to move the gear forward on the Sig, but he assured me that is not a problem here. Of course he says he flies from concrete! Also I notice that the gear is swpt forward a bit which I don't think it was on the Sig model.

Bish,

If you are referring to to the Maxey Hester 1/6 scale Sig Zlin 526 kit, I have the 22 page instruction booklet showing color details.
I also have a copy of Dec. '69 MAN article by Hester about the Zlin project.

If this is what you are looking for, I can make copies for you.

Hi Gene,

The colors are what I am most concerned about. If you can send me that I would be most grateful.

Will you use e-mail or regular mail?

I also have the '69 MAN article and after looking at it, it does provide a copy of a very good multi view drawing which DOES show the color scheme and identifies colors as "red", "white", etc. but to my knowledge no mention was made about what those colors ACTUALLY were. When I built mine, I got the photos that Sig sold at the time. Perhaps they still have them. There were only about 6-8 photos and they weren't great-- a little washed out. I based my K&B paints at that time on my attempts at those colors.

If anyone has a source for reference numbers or a cross reference for colors from this part of the world, it would be valuable to a lot of people.

Bish,

I'll first have a shot of scanning the relevant pages and emailing.

If that doesn't work, I will copy and snailmail.

BTW, unfortunately it was a *lot* more than "a few years ago"
that I acquired this kit.

Bish,

I just emailed you 8 jpg's containing all the color scheme
details from the Zlin kit manual. If AOL balks at the file size,
let me know and I will resend two at a time or whatever
makes them happy.

Hi
I prefer to use 4 cycle engines when I can.

I originally was going to use a Saito 125 but it does not fit in the cowl well. The cowl is pretty narrow. At the moment planning on using a SAITO 91 which I believe will be OK but tight. I suspect a 2 cycle 91 would fit just fine.

The Robart retracts I am using sweep forward about 5 degrees as shown on the plans.

If you are looking for other color schemes check out the Bob Banka catalog. I found some on the WEB but not a lot.

With regards to paint if you liked K&B then try Klasskote. I painted a 1/4 Scale Jim Pepino WW1 Albatross DVa and it worked well. If you are interested, the Epoxy paint DVD from Dave Platt covers a lot.

Cheers

Ray

I have a virus in my computer and it is called AOL. Lord how I hate it. Long story about why I'm stuck with it for now....oh well. Just tried to up load responses to you guys and -poof- all went dark.

Jeff and Gene, thanks for the info and Gene, I get everything in good order, thank you very much.

Ray,

I was all set to order Robart 95 deg retracts and then discovered that Century Jet Models has a set specifically designed for this model. They look good, but cost $375 and I am not sure if that is with or without all the valving etc. Will check it out, but will most likely get the Robarts.

The .91 fits nicely in the cowl, BTW the workmanship on the cowl is very good, just will have to wrestle with the muffler exit.

Thanks again guys,

Bish

Hello

Just came across this thread.

I built the van Mourik Zlin last year (for electric power) and can confirm that it is a great flyer and looks good in the air.

Hi Lew,

Very nice looking model. How does it handle a grass field? Any "nose over" problems?

I have been looking at retracts. At first glance, the plans appear to call for 95 deg retracts, but upon a closer look at the axle location in the up position it looks more like 90 degrees. What did you find and whose retracts did you use?

Thanks for jumping into the thread.

If I remember correct, the retracts are 100 deg travel which gives the forward rake to the U/C.

The retracts I used were from Century, but the torque liks face forward which is not to scale.

No problems at all with nose over.

Originally I tried making the retracts as per plan which, although they worked well enough, were too heavy for my electric power setup.

It's nice to hear that "nose over" is not a problem. I have pretty much settled on the Century retracts since they were designed for this plane. No need to re-invent the wheel!! They are a bit spendy however.

I had not thought of it, but the model certainly does lend itself well to electric power. I have not ventured into the land of Ohms, Volts and Amps yet. What is the flying weight of your ship?

A.U.W. is around 10lbs.

The Zlin has a narrow nose as you know, and an electric motor is easy to install. Also there is plenty space for batteries.

You can test fly the model before painting as well !



Do you have any photos of your model construction yet?

The idea of test flying BEFORE paint is a big plus for electric. BTW, pretty country you fly in. Sort of looks like Boise in the Sping before all the green in the foothills turns brown.

10 lbs is great, my "not to exceed" weight is 12lbs.

I am about to start cutting parts, just finishing up gathering all the bits and pieces. Have to get through about two more weeks of Spring Time "Honey Dos" before I can get to the really important things in life.
It might be fun to chronicle a bit of the built here. I'll see how it goes.

What size air flask are you using for the retracts and where have you located it?

Sorry Bish - can't remember the retract tank size - it's buried somewhere in the wing center section.
