Title: B Yak 9 suggestions
Post by: Carl Cisneros on November 23, 2014, 01:25:22 PM
There we go folks


I know Pat, that is a great kit, but I am building the Brodak Yak9 for the 2015 Brodak contest.

Dennis, I do have the retro fit kit as well, but if memory serves I can not use that for OTS.
Please correct me if I am wrong here.

Am thinking about using the Series 21 McCoy in it tho.

Oh, I am still working on Santa for the Buster 45 kit you are just releasing for Christmas Pat. (Her majesty is still out on deliberation at this time   D>K )
Here are a couple of pics of my new Brodak Buster I just finished for fun flying.

and yes, I do know about the cases on the old red heads.   H^^

Almost forgot, it is all done in Towerkote iron on film. (Painting these days really gets me feeling very light headed and bad feeling.)

For Old Time the gear must be on the fuse.   My Yak 9 I had backin the early 60's had my old McCoy .35 Redhead.   Was a blast for a kid fresh off the farm that knew nothing about flying stunt.

As to Yak engine choices, if it were me either the OS .30/35 or K&B stallion. Actually I would use a Fox .35... ;D

Good job on the Buster.

Thanks for the compliment Ron.

This is the first CL kit build I have since, dang I  can't remember the last time I built a CL kit.  LOL
must be getting older these days ya know.

I am looking forward to building the kit over the winter in the garage and flying it in early spring time and learning the OTS
pattern.  Should be a hoot.

The OTS pattern is challenging, not so much the actual stunts, but getting the old designs to do it. I think the Yak is capable of a decent pattern and a good choice. It would be nice to see. I have been wanting to compete in OTS with a PDQ Super Clown.

Are you omitting the flaps?

The Sterling Yak-9 was my first "big" CL model. I flew it on 52' lines with a nicely broken-in McCoy .35 ($5.98 special). I had a ball with it, and leaned out, it flew with no problems at all. Of course I knew nothing of "the pattern", but did horizontal lazy-8's, wingovers, and vertical lazy-8's, which were sometimes successful, a significant accomplishment, since they did not fill up much more than 60-70 degrees. Mine had flaps and the V-shaped flap connector. The plane is sort of short-coupled for flaps, but mine was purely stock and flew quite well. I lovd that plane! I built another, started around 1960 and finished in 2002, after my 40-year hiatus. It's too heavy.

I have not decided on the flaps or not flaps as yet.

just been looking at the plans and building instructions for now.

I built my Sterling Yak-9 last winter. There's a lot of good reading over at Stuka about these kits. More people than not tried talking me out of hinging the flaps, but I'd never built or flown a flapped plane before and just wanted to, so I did. And I'm glad I did, it's one of the most fun planes I ever flew. It is rock steady in the level laps in both directions and goes wherever I point it. It'll do tricks that remind me of a 1/2A, or make big round turns too. I was pattern flying with no trouble last week on a calm day. But I can't say whether it would be quite as dreamy on a more challenging day.

Actually Ron cribbs gave me the old kit and Fox Stunt 35. I made a laminated fuselage that weighed a lot less than the sterling lumber. With the Fox 35, that lamination turned out to be a blessing too because it's developed a few hairline fractures that I'm sure won't penetrate the epoxy center.

This plane is a blast. You won't be disappointed.
The only thing I don't like is my cheesy looking canopy. One of these days I'll get around to the exhaust headers.

Great looking plane Rusty

I plan on doing mine up in the Winter paint sceme like you did on yours.

Will probably put wither a McCoy 35 or OS 35S in mine.

Hey guys: I saw Carl's Buster.  His job on the Towercoat covering is about as good as you can get.

Carl: be sure to ask Dick H. about what happened to his Yak 9 at the bottom of his third vertical eight at the Norfolk Nats.... S?P

I built one up as a Spitfire, changing the stab/rudder outlines an making pointy elliptical tips  and curved flaps.  The V-shaped flap connector worked fine for the life of the plane.  McCoy 35 and a Fox 35..

Flew quite well and should have no problem with the OT pattern

Ok, I thought Woodbridge was close to the track since my kart club is named after it.
