Here's a project I've been working on a little bit here and there. It's Brodak dope over silkspan tissue on the sheeted areas and Koverall over the wing bays. I used Randolph nitrate to seal the wood and attach the tissue and Koverall.

The tissue worked great. I didn't want to glass this thing and I didn't want to use a gallon of dope and primer to fill the wood. One coat of nitrate and two coats of primer and it was ready to paint with no grain showing through.

The stab is built like a DB stab and was lowered on the fuse about 1/4" or so. AUW will be 56oz or less. It's not really a Super Kaos Jr, it's a Super Kaos scaled down to the Jr's 52" span. I don't have the Jr plans so I don't know if there are any differences.

I went for the simplest color scheme I could think of. It reminds me of a Navy jet. Maybe I should put a big star and bars on one wing.

rainedave,

Hope you don't mind, that I couldn't sleep tonight and began to play with "Paint"![sm=shades_smile.gif]

When the SKJ first came out as plans, my flying buddy at the time and I shared the cost of the plans. We made templates for the wings, cut foam wings, covered them with Poster board and ended up with some pretty cheap good flying planes.

BTW-You've got the 'fit and finish' down to a science... GREAT Job..

Nice looking bird Dave!

Just for interest, here are a few shots of Joe's Super Kaos Jr. taken from the original article in the April 1974 issue of RCM.

Thanks, everyone.

I'm working out a means of painting some lettering on the wings. I'm thinking about cutting a mask from drafting paper, attaching it with adhesive spray and shooting a light coat of clear dope to seal it from bleeding. But, other than that I just wanted a really basic scheme. How did they paint the lettering back in the '60s and '70s? Masking off each letter with tape will take longer than the build did! I don't think vinyl letters will look right on top of dope.

I notice that the plane from the RCM article didn't have wing fillets. Anyone have those plans? I wonder what the original ones weighed. Mine has turned out to be one of the lighted airframes I've ever built for its size at just under 3 1/2lbs.

Rainedave,

I've used gallons of the stuff called "Liquid Masking Film" Greatest thing to ever come along for folks that Paint their finish on the aircraft. I think Dave Platt originally packaged it and sold it. I'm sure a good Engineering supply company may have the same "kind" of product.

Essentially, you Spray a lite coating of this or paint it on with a brush. Draw your design/Letters 'lightly' score it with a #11 exacto then peel up the piece you want to spray and "Voila~" Perfect edges, then when done simply peel the rest off, if you are using an "airbrush" then very little overspray.

That is exactly what I want! Thanks for the info.

Nice kaos jr.
I've noticed some of you have built smaller pattern ships. I have a .28 fsr w/ tuned pipe looking for a home. What plans/designs would fit the.28? I prefer the classic stuff. All wood.
Thanks

Is this the stuff?

antique opa, how about a Super Pacer? #10 on the list below:

An alternate way of masking letters is to cut them out of "fisket film", a low-tack sticky back paper you can get at any art supply store. You can also get letter stencils to trace.

The RCM plans for the Kaos Jr. I have do not show a fillet. The RCM plan for the 60 size does.

YES ! ! !

Thank You!, I am so glad to see that its still around.

Thanks, everyone. I'm going to give the Frisket film a try. It will be easier to cut out the letters in the film on a cutting board than trying to cut the liquid mask on the wings (I might puncture the Koverall).

I wonder if a vinyl sign cutter can cut the Frisket film? I don't see why not. That would make it super easy.

---------------------


Super Sportster 20, New Era, New Era II, Dirty Birdy 20 (can't remember who kitted it - probably Bridi). There were a few for a brief time.


Ed Cregger

anybody got a dirty birdy 40???

Thanks,
Where can I find the plans? Should I just use the search engines? Kinda of a dumb question.
I remember the new era II. I dont recall a db in the twenty size. I guess I could just scale down the 60 size.

A lot of these planes are available from RCM, too (see my link above).

raindave,

nice looking little Kaos !! Excellent work as always.

Suggestion
instead of vinyl letters..... the sign shop can cut shaps/text using "masking" material. This is masking adhesive, so it is removeable. Request they leave a bit of additional boarder if possible. Also request that they do not separate or remove anything after it is cut. Remove the parts you do not need on your own - this way there are no mistakes. You may want to aquire some transfer tape (or use wide masking tape)

MAYA lettering here was painted on using sign shop cut method - Ive also painted some of the racing planes this way. The fun thing is, you can get pretty creative with the mask - often enough a DXF file translates and cuts nicely.

That will give you similar results to using frisket paper, tape, or what ever else masking wise.

Frisket paper is great stuff... Ive used that a bunch of times too.

Probably wise on shooting the clear first as planned.

Thanks, Bob.

So, is the masking material you mention different from the Frisket film?

I'm going to call some local sign shops today and see what they can do.

Great looking Maya! A while back I asked Pappas if he had his plans available. I think he had them for one of his Marks. This is the version I'd like to build:

Bridi / Great Planes produced the Tweedy Bird, which was a .20 sized Dirty Birdy. The also had a Sun Fli 4-20.

my Maya was one of the first batch that Larry Phillips produced. Glass/foam. Built and flew very nicely... had Hanno 61 power.

The masking vinyl is different than frisket - frisket is a bit thinner, and usually is transparent so you can trace on it... and it has a bit lighter adhesive.

The masking material is more like the standard sign material - it is usually white, the big difference is the adhesive. Non-permanent. It is somewhere a bit less sticky than contact paper, but is a bit more sticky than frisket.

You might have to ask around at a few sign shops - most of the good ones will know what you are talking about.

I e-mailed Dean a few times about these plans and he had the Mark II version, I beleive. He was going to get a quote on copying and shipping them, but nothing ever came of it. Dean, if you read this, I would still love a set of plans...


Mark

The original plans for the Kaos Junior states the final weight as 5 lbs.

Jim, around 5lbs is what I'd expect for a forty size plane from that era. I'm not sure what I did to reach 3.5lbs other than select light balsa. I'm also convinced that dope finishes are very light. Maybe by scaling down the sixty SK to 52" I got a lighter model, who knows? Maybe the Jr is built differently (heavier). I can't imagine the older radio gear would weigh 24oz more.

Bob, thanks for the tip. I found a guy who has the vinyl masking film. He claims it works great so I'm giving it a try:
