Wow!

Looks like Coast Guard. Nice!!

What kind of paint did you use?

[John Cralley]

Very nice Rusty, I think the plans you used are probably Pat King plans. Pat has a laser cut Baby R kit for not a whole lot of money. patdk@aol.com

[Ron Cribbs]

Looks nice!

The reason it's a little different is because it's a shrunken Jr. Ringmaster. It's actully a nice rendition though!

[Russell Shaffer]

Yes, it will fly all right.  It would do well with a Baby Bee - that TD will be a screamer. 

[John Kelly]

   ...Hey Rusty, Looks really nice... should fly fine. To get the area, add the root chord to the tip chord and divide by two, then multiply times the wingspan.  Cheers,  John

[Scott Richlen]

wingspan?

[Larry Renger]

I think it should handle 40' lines. .008 steel or 10 lb spectra.

[Roger Vizioli]

          A great flying RM of this size is Pat Johnston's RM 207.
          In our club we have (2), one electric powered and one Norvel .061 powered. Bob Whitney's Electric has functional flaps, my .061 powered, below, has fixed flaps. Both are fully capable of flying a decent pattern.

Rusty, that wing area is appropriate for a Babe-Bee or other detuned 049.  It would be too small for a 020 reedie, although it may work with a TD.  You should be fine with what you have, although you may want to go with a Medallion venturi to tone it down.

(If the engine seems to run nicely, I'd just go with longer and longer lines first, though -- if you use spectras, the experimentation should be cheap).

[John Kelly]

   ...Hey Scott, Wingspan is the length of the wing from tip to tip. Cheers, John

[Tim Wescott]

Tim, I detuned it by putting a medallion crank in it.  Maybe I will take the TeeDee cylinder off and put a standard on it too?   Thanks

See how it flies, first.  IIRC the Medallion venturi is smaller than the TD: I suggested what I suggested to improve fuel draw, not just to make the engine run slower.

[Scott Richlen]

John: you bad! 

[John Kelly]

   ...Hey Scott, Took me a minute to figure out what was wrong. That's what happens when I post when I'm running out the door. I don't know Rusty and didn't know if he might be familiar with different terminology, asking what wingspan was. Then the Light went on when I realized it was you asking him what the wingspan was on his bird. ROFLMAO. I'm not bad... just not the brightest bulb in the pack.  Cheers, John

[Scott Richlen]

Actually, I thought it was pretty funny!

Actually I was wondering the same thing about the wingspan of the airplane.  For that area it must be only about 20 inches.

The airplane looks bigger than that in the picture.

Tim, here is what my investigation found, see pic for proof.

The ID of the TD venturi is .116"

The ID of the Medallion venturi is .157"

But the Medallion venturi has this honkin' big spraybar that gets stuck through it: the TD venturi doesn't.  I don't know the diameter of the spraybar, but I'm sure that the area that's left in the Medallion venturi after it's in is way less than the area of the TD venturi.

[John Kelly]

   ... Hey Randy, Outerzone lists it at 22" , but says to check scaling when printed out before cutting wood.

[Roger Vizioli]

Thank you, Roger.  If you don't mind my asking, is your plane the same as mine?  What is the wing area and weight of yours?

Thanks

Rusty,
no, it's not the same plane. the wing area is 207 sq in, airfoil is "modern" ie thicker!
It is out back in the shop and it is pouring right now, forgot the weight, will weigh tomorrow if rain stops.

Pat also has a RM307, 307 sq in wing. I am using a Norvel .15 in mine but it is too much engine for the plane, planning on trying a Norvel .074 when time permits.

The Tee Dee will run on suction, but not very well. A few layers of pantyhose material will reduce airflow enough to make it work. Those plastic carby bodies are really vulnerable to crash damage, so be careful with it!  Steve

[John Kelly]

   ... Hey Rusty, I have to agree with you 100% on that! I don't know if you know this, but if you click on "more pics" under the picture of the blue and white bird and scroll down... He'd like modelers  to send photos of models built with his plans. I think it would be a great way to say thanks, especially since yours came out so nice! It's got me wanting one! Not to mention the pics of a nice stooge operated dolly launcher for those who like to go gearless!    Cheers,  John

Very nice looking airplane. If it is not in the 150 square inch range it is too small for a front rotary Cox or Norvel .049 . My Ringmaster 150 is designed for front rotary .049 engines, it is not enough airplane for .061 engines. The original Baby Ringmaster is a 21" span, 95 square inch airplane for radial mount reed valve engines. Brodak sells what they call a Baby Ringmaster for beam mount engines, but they only sell beam mount .049 engines.

Rain stopped! :-)
wing span is 31", wt = 9.3 oz as shown in pic.

Isn't 31 inches more like a Junior Ringmaster or did you hit the wrong key?

[Randy Cuberly]

Yeah the Ringmaster Jr is 32 inch span.  I suspect a modern .061 puts out about the same power as my OK Cub .14 which is what I had in mine in 1954 (I think).

It actually worked pretty well!

Roger's airplane actually looks more like a Flite Streak wing than a Ringmaster!

Randy Cuberly

[pat king]

The fuselage shape and tailfeather shapes of the plans on Outerzone are reduced size Ringmaster Jr. shapes. The Ringmaster Jr. shapes are considerably different from the original Ringmaster S1. The thin wing of all the Sterling kits was not as good as the thicker wings we typically use today. Unless an airplane is going to be entered in OTS it should have the thicker wing.

Hi John,
My error if I inferred it was a Baby Ringmaster. Never flew a RM other than the S-1's (since 1952 or 3?) before this one
Span is 31". I will have to compare it to RM jr plans. Pat calls it a RM207 becuse of the 207 sq in wing area.

Hey Rusty!

I use the white glue also and prefer it to CA.  have you tried this: I use the Gorrilla white and dilute it about 10% with water, that seems to make a stronger joint as the glue then penetrates better.  I notice that some of the carpenter glues are so thick that they sit on top of the balsa and under stress just delaminate from the balsa at the glue line.  I also bought a little glue bottle applicator from Tom Morris and it works great.  He has also converted me to using his "one dot of glue every quarter of an inch".  That avoids creating a glue line that is so hard to sand.

Happy building!
Scott
