Author Topic: New Offering From Brodak (Read 27060 times)

Robert Zambelli · « **on:** February 04, 2012, 03:41:42 PM »

Here is John's latest - a mini version of Bob Gieseke's Nobler (or Bear), appropriately called the "Cub".
It is approximately 72% of the original, designed around a .15 engine.
Span: 37 1/2 inches
Overall length: 29 7/8 inches
Stabilizer span: 17 1/2 inches

That shown in the photos is the non-flying display/box art version built by John.
The kit is, of course, laser cut with the typical excellent Brodak quality.

I am presently building the first flying prototype, which should be ready to cover in about a week.

If anyone is interested is seeing photos of the one I'm building, please let me know and I will post them.

Would love to see photos of your prototype and am definitely interested in owning such a model. Any idea when Brodak will offer this kit to the public?

Garf · « **Reply #2 on:** February 04, 2012, 04:25:22 PM »

If this one comes out in an ARF, I will go for one.

Bill Little · « **Reply #3 on:** February 04, 2012, 07:47:09 PM »

I'm glad to see this one. John needed another ship for his .15.

I have the plans from Steve Moon, but a kit might be nice!

Bill - I'm using Steve's plans for the prototype.
A few small changes had to be made.

Hi Bob,

It is kinda a smallish plane for the modern .15s, looking at the plans.

It looks like a good choice for my OK Cub 29.

Nice building John, very interesting, wing area looks right for my .15 diesel engines

how soon can I buy the plan please showing the changes ?

or should I buy the plan from Steve Moon ?

Send me the prototype and I will test it for 3 or 10 years

That looks great. John even gave it the same paint job I put
on the original.

Hi Robert

I would love photos as you build please,

can you tell what changes to Steve Moons plan please ?

I want to order the plan asap

I have a Parra gold .15 diesel waiting for a stunter

John Miller · « **Reply #11 on:** February 06, 2012, 11:29:27 AM »

For those who may be interested, I'm finishing up the conversion of Steve Moons hand drawn plans to CAD in a few days. After I've finished, the new plans will be sent to Brodak for final checking. After that, and any changes that may need to be made, John will have the files to laser cut the kits, and make the new plans available for those who wish to scratch build.

This is a very nice little stunter. It's well designed, with proper sizing for the parts. It should be a great small stunter.

Pat Johnston · « **Reply #12 on:** February 06, 2012, 12:48:33 PM »

At 78%, the total wing area is in the 278 square inch arena. A little bit on the small side for a 15, but not bad. Should have plenty of punch for power.

wwwarbird · « **Reply #14 on:** February 06, 2012, 06:09:04 PM »

Nice to see this. I think we can use more .15 and .25 sized designs. The sizes are less intimidating for newer modelers and they can still be excellent performers for more experienced fliers. Much easier to transport and store as well. Great stepping stones, and hard combinations to beat.

Bill Little · « **Reply #15 on:** February 07, 2012, 03:05:17 PM »

Hi Bob,

What engine (I assume a Brodak .15) and what size tank?

Thanks
Bill

Robert Zambelli · « **Reply #16 on:** February 07, 2012, 06:23:13 PM »

Bill - I'm using the Brodak 15 and a 2 1/3 ounce tank. There is room for 2 1/2 ounces.
I had to trim the tank because of the cowl hold-down bracket.

Vince - I suggest making the fuselage 1/16 wider to accomodate the standard width tank that John sells.

The second mod is to suspend the bellcrank between two 1/16 plywood mounts.

Thanks Bob Z

the plan is now in the post from Steve

will examine all carefully before hacking balsa

I scratch build my own tanks anyway, 2 1/2 ozs

will be plenty for a 15 diesel, pix eventually

I like the looks and I think this one will have to be slipped into the building order. I have multiple .15s to use and only one other very good .15 size model to build.

PJ Rowland · « **Reply #23 on:** February 12, 2012, 11:04:31 PM »

I'd love to build one ! - Looks cute.

Although I would still find it difficult to put a .15 in it..

I remember years ago a friend of mine built a Junior Genesis.. It was designed for a .35 sort of size.. scalled down of the full sized .46 job. - This reminds me of that.. Looking good.

Robert Zambelli · « **Reply #24 on:** February 13, 2012, 06:52:24 AM »

Hi, PJ.
Why would you find it difficult to use a .15?
Too much engine? Not enough?

Bob Z.

I bet it could be electrified...

PJ Rowland · « **Reply #26 on:** February 13, 2012, 10:53:12 PM »

Robert - Your asking why Id find it difficult to put a .15 in it ?

From the mind that brought you a .61 Powered Gieseke Nobler

( I think a .15 or .25 would be ideal - great concept and execution - I just walk to the beat of a different tune )

Peter Grabenstein · « **Reply #27 on:** February 14, 2012, 05:14:16 AM »

Hello from northern Bavaria

dreamin´about "The beautyful red Teddybear", would the OS LA 25 + 10x4 prop a Power-Overkill for this Stunter ?.
Any suggestions ?.
Thanx buddies,
Buddy

Dennis Adamisin · « **Reply #28 on:** February 14, 2012, 06:32:38 AM »

Another great kit in the making - John is sure loading up on designs for the new 15. Of course Brodak has enough electric power systems to make it work too.

I would think that this bird would be great in the new "Stunt 25" event Clint Ormoson & the left coasters are promoting.

Robert Zambelli · « **Reply #29 on:** February 14, 2012, 10:23:11 AM »

Most interesting suggestions!!!
I think this bird would be a perfect candidate for electric.
I will post some closeup photos of the engine/tank compartment and you can get some ideas about battery fitting.

Regarding use of larger engines, it might just be possible. One issue could be fuel tank size. As designed, around 2 1/2 ounces is all that will fit - that is, with the standard hardwood mounts. Implementing a plastic mount may allow more fuel.
Roughly how much fuel would be needed for, let's say, an OS LA 25?

Anyhow, I'll be back home tomorrow and I will see if I have any 25s that will fit. I do not have an LA but maybe I can dig up some OS FP or S models to try.

Bob Z.

john e. holliday · « **Reply #30 on:** February 14, 2012, 10:27:29 AM »

I have Brodak .25's in which the 2 1/2 ounce load of fuel is too much. I do like the looks of the smaller plane.

John Miller · « **Reply #31 on:** February 14, 2012, 11:54:34 AM »

I'm finishing up the CAD drawings for "The Cub". I received permission from John B to slightly scale the size up, as It was a bit small for modern .15s at 289 sq inches.

It now has 338 sq. inches of area, and a span of 40 inches.

The mounts are spaced to fit the Brodak .15, at 1.188" wide.

The tank area is 1.937" wide x 3.466" long.

I personally believe that a Brodak .25 will fit the engine mounts just fine. and the tank, will need to be narrower than normal. likely width that will work 1 7/8" with a maximum length of about 3 1/4"/

Here, for teaser, is the fuselage side view at this time.

Hi John,

I am sincerely hoping to get to work on that little beauty you have drawn up for .15-.25 engines. Complete with build pictures.

John Miller · « **Reply #33 on:** February 14, 2012, 01:32:55 PM »

Good news on that one Bill. Brodak will be offering it as a kit, probably sometime this year. I just sent him a copy of the artwork for the decal.

I have a short kit he cut for me to build, and plan on starting it after VSC.

Cheers, and keep getting better my friend.

Hi John,

That's great news! Will the kit offer the three different size wings? THAT would REALLY be cool!

Having cancer has thrown a monkey wrench in a lot of my plans........ but, this too, shall pass!

Actually the answer is yes, but it doesn't use 3 different wings. The area is altered by changing the rib spacing.

Hi John,

Yes I know about the rib spacing, that is why I said "size", not different wings.

I am definitely building the .15 size. At least for the first one. There might be more!

No that many years ago another kit was supposed to be introduced and I am still waiting on it. I have the plans I got from a person on the forum. It was the "Mo-Best" a design by Larry Cunningham. Just checked and I see the plans are not listed anymore.

TigreST · « **Reply #44 on:** March 04, 2016, 10:06:23 PM »

Bringing one back from the dead maybe. Has anybody finished the build on the Cub and flown one? Would love to see more pictures and any other build details that might be out there. What did you settle on for power, .15 or .25?

TIA.

Doc,
The "Mo Best" was kitted, as I have one of the kits. It's a great kit and should be a terrific profile stunter. Just right for a LA 46 or Tiger 46.
The kit was done by Mike Griffin and laser cut by Eric at RSM. Might still be available!

Robert Zambelli · « **Reply #46 on:** March 05, 2016, 10:25:08 AM »

Just when the Cub was (still is) ready to cover, I got sidetracked.
A home remodeling job and some major landscaping stalled the project.

I have three planes to finish and then I will attack the Cub.

The original plan was to use the Brodak 15 but I may try something else.

Photos to follow.

Again, sorry for the delay.

TigreST · « **Reply #47 on:** March 05, 2016, 04:20:29 PM »

Bob Z. we'll let it go this time, but after this all beats are off!

Google still does not bring up much in way of info on the Cub and invariably routes one back to this thread. At first I was leaning toward the matched set of Cub and Brodak .15 for power,..but dimensionally the Brodak 25 is not that much larger in size and mass (or is it?) ..so why not "go big" rather then "stay home"? Steven Yampolsky had asked a question on the Stuka site about "how to make a plane look smaller". The simple answer would be to simply build smaller airframes. Which begs the question: Why do we tend to build larger models? Yeah, I know,..no matter what they say we all know "size matters", right?

john e. holliday · « **Reply #48 on:** March 05, 2016, 08:19:04 PM »

Exactly, that's what she told me.

Big airplanes are attention getters and some times fly better in some of the conditions we have to fly in. I like the smaller planes as they don't take up so much room.

Robert Zambelli · « **Reply #49 on:** March 06, 2016, 12:44:04 PM »

Hello, Gents.
I did a bit of tinkering today with the Cub.
The motor mount spacing is just about one inch.
Besides the Brodak 15, I think an FP or LA 15 or an ENYA 15 would be fine.
Any good 15 for that matter.
The Brodak 25 and OS 20 are around .10 inch wider than the mounts and I think that they are just too much power.
Also, the tank compartment is only 3 1/8 inch x 1 1/2 inch
