Got a LA-s .46 and have no idea what to build

LAST EDITED ON Nov-23-04 AT 06:23 PM (CST)
 
I have just removed the LA .46 I have out of the Cardinal it was in and replaced it with a FP .40 figuring it would be better suited for the 4oz tank on there. I flew it a few times with the .46 and it ran through that tank in about 6 minutes, it also seemed a little over powered. I am now dealing with the task of trying to decide what to do with the .46, any ideas on a good stunt plane for it?

Robert: though I am not allowed to open a motor up to peer inside, I am told that chamfering the ports a bit on an LA .46 gives them much better fuel economy.

You might contact Bill Hummel and score his Magnum kit....

See Ya

A few come to mind for the LA-46 (and in no particular order...)

Avanti 50
Time Machine 50
Buccaneer 746 (?)
Vector, either the 627 square inch one or the .40 size kitted by Brodak
Brodak Pathfinder
Imitation

etc,etc,etc. There are hundreds of planes that would be good for an LA-46-depends on what you want.

Hi Robert,

Are you looking for a kit, or plans built?

Bucaneer 746, 740, Vector 40, Derringer by RSM, and some of the larger Classic era planes would be good from a kit standpoint.

As for plans, the above plus most any of the ST 46 size stunters.

My Cardinal with an OS LA .46 & a 5 oz. tank flys a 7:35 flight. Checked it about 2 weeks ago. (Bolly 12-4 prop)

LA .46 & a Cardinal profile are a great combination................!

I put an OS 46LA on a F2D combat airplane once. I can't remember for sure but I think it had an 8x10 prop on the engine. My 11 year old Son flew the 1st flight and I timed it on the clock at 114 mph. I flew the 2nd flight, it is much faster than I like to fly. My Son loved it and flew it several more times.

Just came from the brodak site, is the Legacy a good plane? I like the way it looks even though it is at the top of the $ scale I would pay for a Control line kit. I would love to build a built up fuselage Windy's Cardinal but $300 is a little to rich for my blood.

Hi Robert,
The Legacy is a real good airplane!
I will have to let those with more LA 46 experience than I have to speak as to if it has enough power to really fly a Legacy. I'm thinking that the Legacy is more of a ST60 size ship. (??)
Someone will set me straight before long.
Have you checked out the RSM kit of Bob Whitely's Derringer?
Bill <><

Robert,
A Legacy 40 and an OS 46 LA is a great combo. The Legacy 40 is the smaller brother of the full size Legacy. It has 565 sq in. you won't be disappointed.

I recently (two weeks ago)changed out a max40-h to an LA-46 to get a little more power. I didn't have quite enough line tension to be happy. The was about the only newer engine that dropped into the LA-46 mount. It was about 3/16" shorter, so I had to add a few washers behind the spinner backplate.

I ordered it from Tower, with all the apparent required parts: backplate, hex screws, and standard needle valve. I've run it on the bench, and I am hoping that I can fly it before the weather turns.

Regards,
Jim

Tell us how in the world you balance an F2D combat ship designed for a .15 engine to fly with a .46?

I bought 6 airplanes from Larry Skelly. One of the airplanes is longer form LE to TE than the other 5 and is tail heavy with an OS 25 engine. I made an engine mount that sticks out 3" past the front of LE trying to make the OS 25LA engine balance the airplane. I then decided to use a heaver engine and move it back closer to LE. After getting this big engine on the airplane I realized I could have some fun experementing with props. Every time I go UP one on pitch the speed increases by about 10 mph. We have been flying 74.9 mph with a 6 pitch prop, 85 mph with a 7 pitch prop, 94 mph with a 8 pitch prop and so on. The last flight my Son did ripped the wing covering off the airplane. It was funny, we both say something fly off the airplane but we had no idea what it was. The airplane continued around the circle my son said he was giving it full up elevator and it was not going up. It flew about 1 complete lap with no wing covering and skidded across the grass at full speed and killed the engine. No damage to the airplane at all. Some how it never broke the prop either. I put the wing covering back on and we still fly it.

Check out the pictures on this ebay auction 5938077867

See the airplane on the bottom it is longer from LE to TE than the airplanes on the top which will require a heaver engine to make it balance. This is the airplane that I had the OS 46LA engine on.

Here is a pic of my airplanes. Notice the airplane on the right side is not as large as the airplane on the left. The airplane of the right has an OS 25LA the airplane on the left has an OS 46LA. My youngest son was 11 years old in this pic he loves to flies these airplanes.

If you look close at the airplane on the left you can see the bandaid patching where I put the original wing covering back on the airplane with fastcal.

An engine with too much power, I don't think I've ever had that problem (in racing). You could de-tune it to boost economy with a smaller venturi and a smaller hole for the exhast.

I think that the LA 46 would be a little small for the Legacy. I have another one on the building table now with a PA 61 going in it. The other Legacys I had were powered with a Super Tigre 60 which worked really well.
I have an Accentor with an LA 46 which is really great engine/airplane combo. It flies really nice. There are a lot of planes out there that would be great for the LA 46.

Robert,
The obvious choice, to me, is the Imitation. Once you fly one of those you won't go back to anything else. I did not believe it until a good friend let me fly his. With the Imitation you can experiment with a range from .40 to .53 size engines due to the design of the nose. Check out the article that Ted Fancher wrote for MA back in October '79 (or September?) called 'Designing the Imitation' The PAMPA and/or AMA website has the article in .pdf form to download and view in Adobe Acrobat. It is a must read for any control line flyer. I am building an Imitation myself now and it is almost ready for paint. I see Ted at some of our local contests and he is always happy to help in anyway he can, especially if you have an Imitation or a Trivial Pursuit. Good luck.

Olive you keep
on flyn'

Robert,
A Super Ares would be outstanding with a LA 46.

Build a Gypsy. The article should be coming soon.

Hi Keith,
I stand corrected!!
Build a Gypsy, Robert!
When and where is the article gonna surface?
Thanks,
Bill <><

My 46 LA is going on a Fierce Arrow, if you like older stuff. And you would have to build from (available) plans. But you won't See Yourself at the Old Flying Field.

Hi Currell,
Charlie Reeves has a very pretty Fierce Arrow with an OS 40 FP on board. It really flies well.
I built a Fierce Arrow 400 and while it, too,flies amazingly well with a RH 19 I don't think I want to tackle a full size version!
That is a lot of wing.

I've wanted to throw together a Gipsy for a LONG time.

Can I get a plan befor the magazine article goes to press?

I'm tired of waiting!

" What constitutes the dignity of a craft is that it creates a fellowship, that it binds men together and fashions for them a common language. For there is but one problem - the problem of human relations."

Purely for the looks, and I suspect, the stunt potential, how about an Adamisin Gemini?

Buccaneer 740. The Buc 740 and OS LA 46 is an awesome combination. Also, you can get more mileage out of your motor by reducing the nitro. I have been mixing Sig 5% and FAI fuel to create Sig 2.5% nitro fuel to run in my Gieseke Nobler with Thunder Tiger 36. This will get me through the pattern with 2 extra laps. With 10% fuel I could only get through the Hourglass, with 5% only through the Overheads.

For profiles, try the UHP Imitation or the Brodak Pathfinder. Both are excellent profile stunters. The Imitation will use all the power the LA .46 has.

Bill: The original Wild Bill article says the Fierce Arrow has 810 squares. Looking at it setting on the bench, I can believe it.

Someone framed it up many years ago. I made a cowl, fixed up a lot of hanger rash, had to perform Xacto Surgery to reconfigure two blind mounting nuts (width was fine), make "elevators", canopy, etc. The original builder put on trike gear, not the original taildragger config, curved the TE of the fin (original was straight), and I made the elevators with a straight TE, not beveled per Bill. Believe it or not, this was an ebay deal, and I had to pick it up myself, in Pa. Since I visit Va often, it wasn't that much out of the way.

In the Jul/Aug Stunt News, there was a color pic of a teal/black/red/white Ares. I kind of like the unusual way the colors go, so maybe on the Arrow. The teal will come from Rit dye on white silkspan.

>I think that the LA 46 would be a little small for the Legacy

Agree in spades. I have decided on the ST G51 for my second Legacy leaving the option open of going to an ST 60 if the G51 proves insufficent.

The Pathfinder is a made in heaven match for the LA46. For a full bodied suitable stunter in kit form, you are going to have a hard time coming up with anything in the Legacy price range. An alternative would be go look at the many laser cut rib sets available or perhaps look for ribs, ply doublers, and ply and balsa formers for the airplane of choice. Cutting the rest is pretty easy and you can select the wood yourself. Add the cost of the plans, hardware, and wood and you will be close to your price maximum.
Also consider a quality, cored, foam wing. Usually around $35 plus shipping. Straight and only marginally heavier than a built up wing(if at all).
Chris Rigotti(on this board)has some nice looking foam wings. Jim Pearson also has a great selection of nice wings. Can't locate his e mail address right now but he is in Stunt News.

Addendum: Check with Windy or Bill Hummel for Cardinal Evolution plans. A full bodied 40-46 sized Cardinal which should be about perfect for the LA 46. Pearson has the wings available.

The Cardinal Evo is a good idea.

Also the RSM laser cut Derringer, same size, similar layout, but a built up wing.

Profiles take as long and are still profiles when you're finished.

I'm a little late here but my preferences would be along the lines of Palmer's 59 T-bird, or Warden's Continental.

It is my understanding that the GYPSY article has been submitted to Flying Models and it should be appearing in the next several months. It is further my understanding that the Trianic that Allen Brickhaus built has been submitted as well.

OK...

Who do I see about getting a PLAN?

I don't really need the article, I just want to build the plane (This year!)

Or how about a Nakke? Should be real nice with the LA 46, very capable, pretty, classic legal. Kits, foam wings, and/or plans available from Tom Dixon.
