Hi ya all
I have acquired some time ago a set of the Royal P-38 kit plans on E-Bay (or should i say Flee bay
The P-38 is a long lasting dream of mine and will be a long term project as it is far beyond my current flying skills.
Anyhow, being somewhat of meticulous type and a mech. eng. by training I 1st set up to 3D CAD model this bird from the plans, get all the gear set up designed into it and do whatever design modification required before I even touch any Ply or Balsa.
Then the plan is to Laser cut all wing and fuselageprofiles and hopefully to get a most accurately build 38. nice plan….
However, whilst starting with the left wing I have noticed that the wing ribs, properly aligned and spaced, do not form a well flowing wing surface. my suspicious rose andaftersome hours on theweb I stumbled upon a postingimplying that perhaps in the plans I acquired the wing and fuselage ribs may have been a none scaledenlarged copies from the building instruction manual and not royal native drawings or as a minimum outline tracing from the real parts.. Bummer!

So, I am seeking anyone’s advice, if you have a reliable set of plans or at least the true properly sized 2D sketches of the wing and fuselage ribs, and you are willing to share them please reply
BTW, the P-38 plans I got is for a 74” wing span. Not sure if Royal made any other sizes.

Royal only had one size P-38. It was the first kit anounced 1968. It was updated in the late 1970's.
I have noticed a problem with copied plans. They end up slightly longer than the original which makes some parts not right. I do not have a solution yet to this problem.

Scale Dail
Thanks that's a good pointer. I hope someone out there has the habitI have adopted in all my kits so far to trace parts onto a paper and save keep them. you never know when they'll come handy in repairing damaged birds.
BTW, from the picture you may be able to see that after some fine tuning of the 3D model i have managed to get a smooth looking wing. but i would prefer to get some verification that i am in the right airfoil or at least close enough

Just adding to Dail's comments...one should always cut parts as depicted on the plan. If one uses a "secondary" plan, even if "originally supplied" by the kit maker, it may not match the main plan! That is to say don't use other source included to cut ribs, e.t.c. Keep apples apples, and oranges oranges. In other words cut your parts from the main plan only (not some key to the parts...which may be printed). Hope that helps? If there is some small discrepancy in reproduction it will all equal out fairly well (unless really out of whack). It is too bad that we rely on people who don't care always about quality to get some plans. Hopefully some people will help provide here where possible (and for nominal cost). The "templates" often sold are a sure way to differ from the actual plan...so be cognizant. Seems like common sense, but many people are new to building from plans. Stick to the plan ( I think forget this poor template thing...it is meant to offer false value). Good luck!

NB, Is this were you got the P-38 plans?

I got new set from him for a Cessna 310Q and was nice. I havent used them yet
but look like the originals. But in my case I have the Royal kit, just the old plan had
become bug food. so no cutting needed, but i will compare to the new drwg.

You guys probably know this.....but copiers , for lots of reasons, often get one dimention good and one off by about 3%.
Bigger the plans....bigger the errors: a 5 foot wingspan grows by almost 2 inches.
this can make your plans off from your parts, or worse, if your patterns are copied 90 degrees different from your plans, you get errors in both directions.

Fokker, I want to have some more specifics..so I am going to ask the architectural service that enlarged my plans (from a digital file), what errors are likely. It seems probable, and perhaps common sense that errors occur along the longer dimension the most. I hope not to further "rumour" and lack of knowledge on our thread. It is true that paper obviously can expand and contract from a source plan. The scanning of any plan may also introduce an error. I am completely lacking in personal evidence of this in my dry Colorado environment (fairly stable humidity). It exists, though to some degree. I think the problems are minimal if one cuts all their own parts from a plan themselves from that original source. I don't mean to enhance a discussion that is beyond most of our concern, but if anyone has significant experience or concern here...weigh in! Years of plan building modelers have succeded without much complaint here, I must add. Who knows what these Ebay plan providers are using for source or equipment however.

These are the exact reasons as to why I am hesitant on buying royal plans on ebay and building the b-17 from scratch. "YOU CAN'T TRUST THE ACCURACY OF THE PLANS ON EBAY, THESES GUYS ARE ONLY OUT FOR PROFIT". Thus is why I have to buy a kit, trace the parts and then build.
#737

I am currently working on a royal b-17 of I am the 3rd owner/builder. The original builder handcrafted a set of homemade B-17 type retract/landing gear which look and operate just like the real thing. It'sabout 80/85% finished and tonight I'll be finishing sheeting the wing and starting to plank the fuse. I alsohave a royal Zero .60 N.I.B.I hope to get that startednext year .

The printing company that I use for plans copying garentees a 100% accurate duplicate. They say they have to keep it calabrated for making structural blue print copies.

I don't know if any of you guys use this little tip but whenever I need to have a set of copies made up for templates, somewhere on the plans I draw a fairly precise line of 12 inches in the length and width directions of the plans. When the copy is made, I then measure the lines to ensure the lines on the copy is exactly 12 inches. If it's off, the operator can usually adjust the scale in both directions to get you extremely close, close enough not to matter much.
One example in the past, I brought a set of the .60 size Macchi C202 plans from Dennis Bryant to our local blueprint shop to have a set made for templates. After the operator set the copier to 100% and made the copy, I measured those lines and they were definitely short. Did the calculations to find the necessary multiplier and it turned out to be 103% to get the right dimensions. He was guilty of assuming that the machine was working fine. After he was done doing mine, he placed a call to the service company to come out and ensure his machines were properly calibrated. He thanked me for pointing this out by making me a second set on the house in case I want to do another in the future.

The world is short one Royal P-38 today. My over 25 year old P-38 died over the weekend at the 1/8th Air Force Fall Fly In. It was some type of signal loss as halfway through an 8-point roll the engines went to idle and none of the controls worked anymore. A spectacular crash witnessed by many! Thanks to Mitch Baker, here are the last pictures. Crash investigation is under way. This one will not come back[&o]. I was hopeing for two this time next year

Man, sorry to see your P-38 went in...[

Out of curiosity, what radio were you using? I lost my P-51 at the East end of the field on Saturday to a radio lockout, on JR 2.4...

I guess I am a bit sick about that Dail! I so much liked your posting an early picture of that model early on. Such a beauty..while it lived. Important thing is the creator of the model, so...make a better one (yea, I liked the old one too). It IS a lot of work to make a nice Royal or other kit, or scratch-built! Breath in..Breath out (repeat as necessary)! I am officially comisserating with you. -Eric
As author of this thread....I hereby declare a day of mourning for Dail's P-38 Lightning of yor!! "Seconded and motion passed".[&o]

I think everyone took a moment of silence on this one...and choked back a few tears...
Ah well, ya got to celebrate the good life it had and the awe that it inspired for many.
My 10yr old boy asked me the other day after getting home from crashing a fellow members plane,
'Dad, did we have a good day?' (he was pretty upset), I said heck yea son, we had a great day!
We've got lots a glue and plenty of wood, we'll build TWO new ones, one for Mr.Jerry and one for us.
They may be a new planes when we're done but her spirit will fly again!...now lets go show mom the cool pieces!
