Hi Chuck,

Thanks for the link to the V-Girl. That is the first time I have gotten a good look at one. Looks to be the same plane that is being ROGed at the camera in, "How to Design and Build Model Airplanes." Most definately a keeper!

If you build the 'V-Girl' for R/C would you use coupled rudder-vators for control?

Does anypne have the 'Swanky Doodle' plan / construction article from the November 1956 issue of 'Young Men'? It is another sharp looker that much resembles the 'V-Girl' but with a more conventional tail group ..... and according to Keith it is one of the best performing models of the lot too!!!! If I can get my scanner working (damned to those 'All-In-One' machines!) I will get a scan of it for posting here.

Donald,

If you go to page one of this thread, I posted a picture of the 'Swanky Doodle' and a rought scan of the plan. As for who has the most or all of Laumer's plans, that has to be Mr. Fritzke (Santa Claus). I'm trying to prompt him into dedicated his next website posting to all of Keith's designs. (Daves got a great website) As for the V-Girl, if you look at the v-tail support, it's a piece of 3/16" sheet. Since it's so long, you might be able to section part of it out as a rudder. You'd only have to make sure that the section above it is reinforced to support the v-tail. It's going to be interesting to figure out the best way to control this little guy: Are you going to be the first?

Yep, that was me. Here's a small teaser. Send me an email addy for a 250K gif delivery. Anyone else want it at the same time?

OK guys, here is the start of it:
http://my.pclink.com/~dfritzke/Laumer/Laumer-Page.html
Send stuff you want in there. Gene Rock is tiling up the
Lizzie and working out the V-Girl.
Its a bit rough, I need to resize those jumbo pix and create a link FROM the
main page...but time for bed!
Got 4 in there now.

I talked to Keith on the phone about 6 months before he died.
and I have a letter from him.
I sent him a movie of me flying my version of his Sharp Scooter
I never heard back, so I dont think he ever got to see the movie.
I still have the Sharp Scooter

This is great! We talked about getting a collection of Laumer plans about a year ago but some of the difficulty has been finding all the plans.

Everyone please chime in and provide Fritzke what you have. My goal is to build the Little Red Twin sometime soon...

I would also like the plans for that Tiger Moth = neat.

I will go back and check what I have in the plans piles...

Brian,

I got an e-mail form Dave last night and I think he's planning to post his collection of Laumer plans on his new site. I'm fairly sure he has the entire collection.

Speaking of Laumer, he seems to enjoy allot of twin rudder designs: Here's an article and a few pics I gleaned off some of these forums that show how to use the stab hinge as a rudder actuator!

Sombodys thinking outside the box!

VERY slick rudder system! Where was that from?

BMJR now sells a Little Red Twin kit:

http://www.bmjrmodels.com/catalog.cf...20Model%20Kits
I don't see the Twin Lizzie there anymore, but they made one a while back.

I am adding that link to the page, as well as a link to Flying Models Magazine
plans page for Milton's version of the Twin Lizzie Twin (April, 2006, $12), and to the other
published version of the Lizz that was an enlargement (Paul Denison, MAN, April '78).
I do have all his designs, but my magazine collection is still, shall we say,
somewhat disorganized. I was happy to find the Twin Lizzie article in
under 20 minutes last night.
SO, if you guys have stuff you want to see on that page, send it!

Dave

BMatthews

Yep, a slick rudder method. Twin Lizzie HERE WE COME! ! ! !

KidEpoxy

I saw the B24 for .10s had a burried crank, wire, & horn set that I really didnt like,
I am totally going to use this method instead.

what is the common setup for the bellcrank axle bolt? Woodscrew or machine&nut or ??

BMatthews

Control slop in pivots or where the wires connect is not a good thing. Especially if it is sealed away. So I'd suggest you either use a screw through a bushing of brass tubing or just use a section of music wire or even go out and buy some 3/32 or 1/8 steel dowel pins and glue the sucka in place using a precise drilled hole for a slop free but not tight fit.

Done this way birch ply works well for bellcranks. Drill with a number drill about 10 thou undersize then harden the hole with some thin CA wicked in. After it cures then drill with a nice sharp 1/8 drill and test the fit. It may be a touch squeaky tight at first but a little wax in the hole and a bit of working it should produce a nice slop free but still free to move joint. Don't seal it in if there's still some sticktion. If need be free up the hole with the number drill that is just a hair oversize of the pin, wire or tube bushing.

I've done the same thing for the wire ends in these plywood bellcranks.

Or I suppose you can cheat and use some sort of metal or plastic.... In Ye Olde Dayes we frowned on metal to metal contact so I still tend to make my control horns from plywood, Epoxyboard or plastic.

BMatthews

Just sent Dave my scans of the Swanky Doodle and Buttons along with the first page or two of the articles so there's some pics.

David Ingham

Here are pictures of My Flea Whiz.
It is about 1.4 times the size of the plans in How to Design and Build Flying Model Airplanes. I made the inside wing one segment longer, split the spar to make room for my son's action figure pilot and maybe reinforced the spars near the root. The rudder is aerodynamically compensated, LOL. The sliding canopy is from a Pepsi bottle, brass tubing and music wire. Note the storage scope type analog radar screen and the match stick.
I especially like the swept forward tapered wing tips. That makes it more resistant to cross winds, like negative dihedral. (Maybe the wing shape should be reversed for RC?)
It has a Cox 049 reedie, with a muffler. It flies gently on this scale with this engine.

Dave, love the Flea Whiz! Great cockpit details. The sliding canopy is a great touch as well.

Question: Does the cockatiel feather enhance the belcrank performance?

I would like to find a copy of his book.

Robert

BMatthews

The Flea Whiz converted to RC would be a nice one. If Bipe hasn't sent Dave the plan scan yet then I can. The mid wing setup pretty much would call for a one piece model or slip on wings. I'm not a big fan of huge fuselage cutaways. And you wouldn't want to move the wing down since that would make it look a bit much like "just another Sportster"...

Robert,

Check Amazon.com for Keiths book on "How to design and build model airplanes". There's a few there, but expensive: $72.00 to $94.00. I know I've seen them else where for allot less. Maybe E-Bay?? Just search the internet, they're out there.

BMatthews

I'd love to get a copy but not at that price! ! ! !

That book was one of the first I got from the library back in the mid 60's.

You need to use the "Laumer Special" muffler on these models:

Anyone out there know of a quick and true way of sanding an airfoil shape into a 1/4" solid balsa sheet wing?
I'm looking at building the Laumer Dub-l-dek-er and that's how the wings are done.

thanks, chuck

David Ingham

Budgerigars (parakeets) are great pets for a 1/2A person who likes sort of random jazz. We have not clipped their wings since the first molt and they go in their cage only at night. They can hover and fly backward a bit but are not good at it like humming birds. They weigh around an ounce each. We rescued an Amazon but had to sell him. We called him (or her) Girlieman.

David Ingham

A miniature plane (excuse the pun) might help. (The time I did that the wing was too thin for its cord to fly well.)

Another good source for Keith Laumer's book "How to design and build model airplanes" is www.abe.com. There are usually several to choose from at various prices.

I am also hoping to get a copy soon.

Chuck,
Get yourself a Stanley mini trimming plane, they make short work out of those kind of jobs:

Under $7 at Lowes
Dave
OOPS NOW I see Dave I. has already hipped you up on the mini-plane!

I have added Buttons (thanks Bruce), and a bunch more to the page.
