I have completed another warbird. If enough interest is shown, I will do up a good set of drawings. Probably $15.00 to your mailbox. Yes, it is a warbird. Google the Civilian Pilot training program from WWII. Many military pilots got their first flight training in these. 465 sq. in, 21% tail, full span flaps, lines on vertical CG. For 36 t0 46 engines. Will post results after first test dflights.

The quintessential Bug Smasher.
I'm real curious how a flapped high wing Stunter is going to perform outside loops vs. inside loops equally.
Keep us posted. Looks awesome!

Not intendng to steal any of Don's thunder here, but to the question about high wing flapped stunt ships. Dick Mathis did a profile Citabria, full flaps. He wrote and others who were familiar with the model said it flew just fine. There have been good reports also on the Palmer/Goyet High Boy.

Turn it upside down and it looks about the same as any other typical stunt ship. I expect no problems at all with it. Flaps are easily adjusted to equalize the turns, same as any other model. How many copies you want?

Mike Keville · « **Reply #4 on:** August 03, 2012, 06:42:33 PM »

If it flies as well as a (non-flapped) Box Car Chief it will be a superb performer - as are all of Hutch's designs.

Don,

I'll take one as always. Your plans are a work of art.

Steve

Douglas Ames · « **Reply #6 on:** August 04, 2012, 09:23:33 PM »

Please post when the plans are ready. I'll take a copy.

This would look stunning in SIG's Blue & White sunburst scheme.

FLOYD CARTER · « **Reply #7 on:** August 05, 2012, 10:05:26 AM »

The high wing model will fly OK, but the leadouts at the wingtip must terminate at the fuselage center of gravity. That means a line guide below the wing.

High Boy has leadouts through the top-mounted wing. This makes it impossible to trim because the center of mass doesn't coincide with the point of line connection (pull). I have 2 flights on High Boy, and the roll axis isn't too bad, but it will never fly a good pattern.

HI Don,

Not THAT is a often overlooked "War Bird"! I will want a copy, of course.

Thanks!
Bill

Don Hutchinson AMA5402 · « **Reply #10 on:** August 05, 2012, 09:55:17 PM »

Floyd- Look at the photo and you can see the bellcrank in the slot in the cabin windows and the leadout guides (infinitely adjustable) at the tip. Hanging by the leadouts shows the wing straight up and down. Only about 105 in my shop these days, guess I better bring the drafting board inside and get to work!

Here is another picture of Don's beautiful Cub. This was taken at the Dallas club meeting.

The "N42222" is from Dale Gleason's full size Cub which is hangared at Hartley Field which was an Army primary training field during WWII.

Hartley Field was also the location for flight pictures in the Pancho Barnes TV movie, starting Valerie Bertonelli.

Hutch strikes again!!!

Very neat idea Don and another great offering. And, as you'ved noted, it will fly just fine as long as the builder/flyer sets the leadout exit to jive with the vertical CG. I can confirm that without any doubt from flying my PBY, it works. It's very easy to do like you say Don, just hang the model by the leadouts and adjust the exit appropriately.

Along with the military stuff, there are a lot of civilian schemes that would look great on this model too. Hazel's would be really cool.

Dennis Adamisin · « **Reply #13 on:** August 08, 2012, 05:06:22 PM »

GREAT ONE HUTCH!

My Hawker Typhoon had the wing 2" (!!!) below the thrustline - flew fine. How far is the wing from the thrustline on you Cub? Of course I would electrify it with the battery in the wing, the vertical cg would not be an issue at all.

Some cool civil & military color schemes. I like the L-4 version with the extended greenhouse.

Don Hutchinson AMA5402 · « **Reply #14 on:** August 09, 2012, 10:00:57 AM »

The wing is 3 inches above the thrust line, the stab is 1.75 above the thrust line. I don't expect this will be a problem. Have not gotten any flight info yet but expect it will be good. A fresh drawing is presently underway, the first rough draft was cut to pieces building the model. Will post when it is ready.

Dennis Adamisin · « **Reply #15 on:** August 09, 2012, 09:23:53 PM »

I should have also added that I had the leadouts in the wing, no dihedral - so your layout should be better than that WRT vertical CG then mine was, and mine flies fine.

This is tangent to the topic, I was a Judge at the NATs for RC Scale Sailplanes when a competitor showed up with a TG-8 (google it!)

Repro work done today, first batch of prints go into the mail tomorrow. Have a few left, let me know if you would like a copy. Hope to get some flight reports soon.

Hi Brother Don,

Looking forward to the plans. I have the ribs for the P-38, and hope to build it as soon as I can get back to really building full time.

Thanks!

Received my plans today. Very neat!

I like the way the bellcrank ties into the engine crutch.
Once the major parts are cut, looks like a quick build!

Your USPS M/O will go out in tomorrows mail!

Thanks, Don

Mine arrived today. Another work of art. I'll put your check in the mail in the morning. Thanks again.

The previous thread lists those CLC has, I have two drawn since then, the P-51 H and the J-3 Cub.

Put up the first flights on the Cub today, Dale Gleason at the controls. Turns great, should be a fine flyer. Photo of happy pilot attached!

Hi Don,

Are you running a Magnum .36 XLS in that one?

Thanks!
Bill

Don Hutchinson AMA5402 · « **Reply #27 on:** August 23, 2012, 04:37:48 PM »

Yes, it is a Magnum .36XLS. One could also run an LA 46 but it wouldn't have to work very hard! The CG would come out a little better but this is not a big airplane, only 465 sq in. wing, 22% tail and weighs about 43 ounces.

Bill Little · « **Reply #28 on:** August 25, 2012, 01:55:02 PM »

Thanks, Don!

Maybe an OS .40FP if a Magnum .36 isn't available.

The 40 is just fine if it is a good runner or has been retimed.

I'm wondering what are all the others of Don's Warbirds. I know about the Dauntless, the P-38, and I think there's a P-51 and maybe a Corsair? I can't think of another one.

A list would be good! Maybe it's time for a Don Hutchinson's Warbird Plans forum down in the Vendor's section? Bill, can you set that up for Don?

Hi Steve,

Of course I could set up a Vendor's Corner section for Don, if he wants it. I need to hear from Don before I do anything like that.

Steve and Bill-
I do not have the masters of the warbirds anymore, I gave them all to Control Line Central as shipping one or two prints every three months was just a pain to me. The only two I have left are the P-51-H and the J-3 Cub drawn after the fact. The list of all the others is on the web site in reply #23 of this thread. If it was a single engine (except the P-38) US WWII airplane, it is probably in the list. Some drawings show numerous versions of the airplane. P-51, 6 P47, 4 P-40 2 etc.

HI Don,

When you feel up to it, a P-39/P-400 would be nice!

dale gleason · « **Reply #35 on:** October 09, 2012, 12:21:30 PM »

I just now stumbled onto this thread. The "little yellow Cub that thought it could" has a few more flights on it now. Two quick training flights with Test Pilot Gleason's Grandson, Mason, revealed some motor issues, and some trim issues not previously noted.

The motor, Magnum 36XL, tended to run on the "too warm" side, even in cooler Autumn skies. This seems to be totally remedied by opening up the venturi size, to .250, using stock needle/spraybar. 11x4 Pro Singer, GMA 10/11l11. Steady four cycle at 10K, cool, happy, motor.

Leadouts moved aft and farther down has solved the vertical C/G issues. Before the leadouts were lowered to their present position, flap tweaking was band-aid enough to allow a 2nd place finish at the recent Tulsa GlueDobbers' meet in Profile. This plane lands itself, when the motor quits, don't do anything, just watch and enjoy.

Baton Rouge is next on the tour, hope to have the "Yeller Cub" in total trim by then, competition will be very tough, there will be at least two other Hutchinson planes there, the T-6 of Joe Gilbert and Don flying his own "Dauntlass", plus everyone else.

A cool feature of Don's Cub is a small hole under the wing near the root in which you place a ball driver and adjust the flap throw. This is accomplished without changing the elevator throw. I'm taking out just a smidge of flap travel. dg

Steve Helmick · « **Reply #36 on:** October 18, 2012, 10:37:15 PM »

What changes would be required for a J-3 to be modified into a Super Cub? If this thing flies good and looked like a Super Cub, it would be ultra cool setup with Tundra Tires for bush plane work...i.e., flying off a rough grass flying field.

This brings to mind that the DH Beaver was used in WWII, if I remember right. Could be wrong, often am. Just today, I thought it was Friday, and the boss came home and told me it was only Thursday. Retirement is great! Anyway, the Beaver would be cool for Profile Stunt also. They're not small planes, so a bigger engine (ST G.51?) would be neat!

It sure would be nice if we could actually get Don's plans. But it seems that the present distributor of those plans has, for one reason or another, ceased to operate in that capacity.

I'm still trying to get Dauntless plans. But no luck.

Tom Niebuhr · « **Reply #39 on:** November 15, 2012, 10:27:08 AM »

Don had given all his masters to the "distributor". I have files to make laser ribs for several of his airplanes, and stopped working on several when the plans were given to the "distributor". With Don's permission I will again make laser ribs available.

Don, hopes to possibly make the drawing available for Pampa products.

Move the pilot from the back seat to the front seat. SInce you have flaps it really IS a Supercub, right?
