Hello,
 
Does anyone still have the December 1979 issue of RCM&E lying around somewhere?
 
It features the David Vaughan P-51B design that I would like to build.
 
Seems the publisher doesn't have one anymore . . .
 
Thanks!

Barry,
 
 
Wait a minute!
 
I got an e-mail from the publisher himself, he states that they must have the issue . . . 
 
Thanks for the effort, anyway!

I have a copy and I am sitting looking at it!
 
There are some notes in the text that seem useful if you are building from the plan.
 
Let me know if you want a copy.

That's good news, KC!
 
I have a copy and I am sitting looking at it!  
 
That's a big thumbs up for the way you organise your sources!
 
If all other opportunities fail, I'll turn to you.
 
Even if it are just some notes, I really would like to know what the master himself said about the plane and its construction.
 
(You probably all know that this is the best P-51 model design ever!?)
 
I'm going to build her 20% enlarged, i.e. 84" wingspan.

It is full of little tips on construction that are original.  Ideas for making the cowl and making it fit nicely, curving balsa instead of planking etc.
He does advise that a beginner " should wait until he has  a  Lancaster or 2 under his belt" !!!!
 
Of flying he said "never once did it drop a wing"  and " stall is gentle and straight "
 
What little of the plan that is shown in the mag shows it is  full of notes on construction.

I already have the plans; I just want to know what he says about the construction.
 
I haven't built two Lancasters (yet), but I feel confident I can manage the build.
 
The plans were drawn end of the 70's; nowadays (30 years later) we have quiet a lot of extra resources (hinges, electro motors, Profili, e.g.), that make the life of a (scale-)builder a lot easyer . . .

If you want a scanned copy of the article send me a PM with your e-mail address.
 
If this model flies so well why build it at a larger scale which will surely entail much redesign?
I would have expected that the Brian Taylor P51D at the same size 69" would fly equally well.  ( note the Taylor  plan supplier has a canopy avail  which says D or B )

Well , I just wanted to build a somewhat larger model.
 
There will be some redesign involded, but not that much: electro motors put less stress on the airframe!
 
I also wanted some nice and good retracs, and bought a beautiful set from Sierra Precision, that were made for the 84" TopFlite Mustang.
 
So, that sums it up, i think.
 
And yes, I would like to have the scanned article!
 
Thanks!

So, now I have the plans and the construction article, and as said earlies, in the article he claims the model flew great.  Smiley

He also says that he drew the plans after he had built the model that flew so well.

So far everything is fine, but on the plans are some peculiarities, that I would like to discuss with Mr. Vaughan, or have clarified in whatever way.


There is a CenterLine (CL) on the plan for the fuselage.

Compared to that line, the motor is drawn with 1.1° downthrust, but on the plan he says: 2° downthrust!  Undecided

Compared to the CL the wing has an angle of attack of approx. + 0.4°; that's what is drawn.

But may be Mr. Vaughan thought it was + 1.0°, because he hasn't drawn the center line through the rib in the right way! (Mistake?)

The tailplane is drawn at 0°, but there is a text:
   Tailplane shown in neutral (that's correct (jb.))
   Original use + 1° pos. incidence.

Undecided

Of course I would like to build a model that will fly as good as his model did!

But what values should I use???

So, if anyone knows the answers to my question (what is the proper setup), or knows how to contact Mr. Vaughan, please.

Thanks!  Smiley

Point taken.

If (I say if) I am starting a build, it will be the original size.

(Has anyone built one over the last ten (!) years?)

Hi Martyn,

 

That's really great, to hear that there is someone else who wants to take her on!

I have the construction article; send me a PM and I will scan and mail it to you.

Out of interest this is 'Joan' as she is today, not bad for a model 30 odd years old.

Richard, do you now own David's original P-51B model?

I remember reading the original build article in RCM & E. The model was and still is a masterpiece.

This is David's original Mustang that won the world Champs, it has been boxed up for storage by his son. He was trying to find a home for them so that they could be preserved and viewed, I am unsure how he got on.

I remember David saying on a few occasions up at the patch that his models should have a 'Viking burial' once he had passed.

Considering the Mustangs its age its in pretty good condition, everything made from scratch. He was a master at weathering which at the time had not been seen before in this detail (so I have been told).

If you are interested I have photos of some of his other models that his son took before boxing up?

I remember this, I had the mag lying around for years until I had a clear-out. Great to see it still exists, if anything the patina of age makes it look even more realistic.
