The subject plan is finished and copies made. It is #13 in the series and looks like it will be a really good flying airplane. For an LA46 or equivalent. 537 Sq in wing, 21% tail, CG looks about right with no lead up front. Looks cool too, should outperform all those "D" models out there!

Don,

Many thanks to you!!

I get Plan Number 1, right, or is it Plan Number 2??

Regards,
Jim

1. Need to get more shipping boxes from the PO before others go out. If anybody orders one!

What is the wingspan? In this age of smaller vehicles, this is important.

BTW, my Plane and Pilot magazine arrived today and the article on "The 10 sexiest airplanes ever" lists the P-51 as number one.

Sent you a PM order.

Guy,

Don will probably reply.

Since I haven't seen the plan, yet, I don't know the span of the "H'; however, my Pat Johnston "D" model is 52.5" span with 565 sq. in. area. The "H" will probably be slightly shorter span at 537 sq. in. area.

I'm sure you know the wing planform of the two models is different; that difference may require a slightly longer span for an "H" than for a "D" of the same area...........

I was impressed by the flying qualities of Don's SBD and his AT6 that Joe Gilbert now flies at the B.R. contest. I believe the "H" will be a great flyer as well.

I have Don's P47 plan and need to get his Sky Raider plan, too. The Sky Raider isn't often seen as a CLPA model, other than the old Midwest design.

Well, no it isn't a little smaller, it is actually 56" span. I did not widen the chord from scale so it is the same aspect ratio as the real thing. Just a bit larger than the Dauntless.
Just a note here on cost. Due to higher repro and mailing costs and miles driving to the PO and repro center, I am asking $25.00 rolled and shipped priority mail.

Hi Don,

Thanks for the correction.

I wondered if the A.R. of the H was higher than the D because of the different wing planform. I think Pat's D wing has more chord than scale, too, so span is a bit shorter.

Jim

Don Hutchinson AMA5402 · « **Reply #8 on:** November 11, 2011, 09:16:23 AM »

A quick check of my resources shows the D and the H wings to be very close to the same AR.

Here's a photo of an 'H' model -- admittedly a restored two-seater but nonetheless accurate. Note: apparently the 'H' model doesn't have the wing's LE 'cuffs' at the root (?).

That's the way it is in the drawings I found on a Russian site too:

CORRECT. Late series "lite weight" P/F-51's also sues smaller wheels because they were no longer expected to fly from turf fields. Smaller wheels eliminated the need for the cuff.

Jim,
A slight correction in that my 565 inch Mustang has a 54.5" wing span. That is about a 5.25/1 aspect ratio. The "H" model discussed here will make for an easier build that a wing with the "cuff". However, the cuff is so much a part of the Mustang that it kind of looks funny without it and really makes the "D" model as a stunter stand out.

Absolutely! The P-51D plans I did previously had the cranked leading edge, 6 profile variations of those that escorted the bombers over Europe plus a photo of the flight line of them at the Minnesota ANG where I was a mechanic.

Hi Pat,

I took the 52.5" from the plan data (I think I read it right, maybe??). Should have measured my model, but it's probably somewhere in between

Anyway, if flys fine!

To those who have ordered plan sets, I am waiting for the PO to deliver the mailing boxes to me. Be patient, the plans should go out to you this week.
Don

Don Hutchinson AMA5402 · « **Reply #16 on:** November 26, 2011, 02:09:42 PM »

A week later I am still waiting for the shipping boxes. If they don't show up in the next few days, I will send the drawings out folded in a large padded envelope and reduce the price. Sorry about the delay, next time I will order up the boxes well ahead of the need date. If you would prefer to wait for rolled drawings, let me know.
Thanks for your patience,
Don

I'm in no hurry. I'll wait.

These are the usual builder's plans from Don and it is a great looking subject!

Thanks, Don.

Bill

P.S. Can you list the 12 other plans? I don't have 12 of yours.

Don Hutchinson AMA5402 · « **Reply #19 on:** December 18, 2011, 01:43:31 PM »

All my earlier profile model Warbird plans now reside at Control Line Central so you can order them from CLC. Here is the listing of them, all are about 500 sq.inches wing area and very close to scale in profile. They fly really good with an OS LA 46 up front. Some drawings have several variations on them.
1- North American T-6-G. A killer, ask Joe Gilbert!
2- Douglas SBD Dauntless. Ditto, I do OK with this one myself.
3- Curtiss P-40-C Flying Tigers and P-40 Q bubble canopy version
4- Grumman F6F Hellcat
5- Lockheed P-38 for two 25's, larger wing area.
6- Grumman TBF Avenger
7- Douglas AD Skyraider
8- Vought F4U Corsair
9- Beech Staggerwing
10- Stearman PT-17/N2S-3
11- Republic P-47 Thunderbolt, 4 versions, razorback and bubble canopy. Also photo of the very one I worked on in A & E school.
12- North American P-51 Mustang, 6 versions, razorback and bubble canopy. Also photo of the Minn. ANG flightline where I once worked!

Thanks, Don! (and thanks again for the plans)

I don't have the T-6, Beech Staggerwing, and PT-17. Need to get those one day! LOL!! Of all the other 9, I will build (in order) the TBF, P-38 and P-51D for sure.

(not sure which ones Aaron will build)

Mr. Hutch sent me the (H) this week in a padded mailer and they arrived in great shape and the plans are outstanding. With contest grade wood it will be very light and with 6-8 it will still come out very light I believe. I have held the T-6 and the Dauntless in my hands and they are light, and they are still sturdy with hundreds of flights on each one. Of course, Mr. Hutch was the builder of both and he is the absolute "Pro" in building light and strong. I have seen both planes fly many times and they are very competitive. Joe Gilbert is using the T-6 with a Saito 40, and it is one potent combination. It flies like it is on "rails". If you want a semi-scale good looking warbird then get Mr. Hutch's plans, and if you want a competitive profile design, then get Mr. Hutch's plans. And NO, I AM NOT PAID ANY COMPENSATION FOR THESE ENDORSEMENTS. Seeing is believing! Both also fly very well with LA 46'S. Thanks Mr. Hutch for these fine looking, and fine flying designs.
Doug

Bill Little · « **Reply #22 on:** December 20, 2011, 12:08:27 PM »

I agree, Joseph. I am going to use a modified HP.40 in the Mustang and probably a ST .46 (w/Bristunt ABC sleeve/piston) in the TBF. Going for the "sound" so to speak! LOL!! The HP is a much higher rpm engine (R/R Merlin!) and the old ST is a growler (big radial).

I do like to play around a bit.

If you use an LA 46 on the profile Mustang what prop brand and size would you recommend and what size spinner and brand would you use? What do you anticipate the final weight will be of the complete aircraft?

Thanks

HI Peter,

It seems that the hot set up for the LA.46 is a 12.25 X 3.75 APC or an 11.5 X 4 APC. Haven't got an answer right now for you on the other topics.

I'll take a shot at it. The T-6 and the SBD both came out about 47 ounces but they have a bunch of lead in the nose being radial engined airplanes. The SBD's is about 6 ounces! I would guess one could bring in the a Mustang at about 42/43 ounces. Note, both the T-6 and the SBD are reallly good flying airplanes, winners at many contests at that weight. As for the spinner. Alas, the real Mustangs had a huge spinner, the H plan would have it 3.5 inches but by moving the backplate line forward, I have it at 2.5 inches and I suggest the bluntest shape you can find. I am now using the carbon fiber 10&5/8 x 4&1/4 Phelps prop from Eliminator props and find these work real good. Set between 9800 and 9900 on the ground.
First flew the T-6 with a Magnum 36XL and the SBD with a retimed OS 40FP but find they really come to life with the 46.
