Paul Sherlock, in the early '70s had a 12' model of a 747 that was powered by two SuperTigre .60-size engines throwing props. They werre mounted in the inboard nacelles. He had an article in the '69 (I think!) DCRC Symposium's publication. RC Modeler Magazine published it for years. In that article, he suggested taking a Clark Y modified in thickness as the basic airfoil. It apparently worked.

He made models of a VC-10, B-727, Learjet, and others (don't remember). All were of foam construction with ply and hardwood reinforcement where needed. The 747 fuselage parted just forward of the wings and just aft of the fuselage main gear bogies. Wings were plug-in.

I no longer have that collection of articles from that particular copy of the DCRC Symposium article collection. There were several that were very interesting.

Bax,

I think this was Paul's foam B-747. The attached pictures were taken at a model meet in the summer of 1968 in Central California. The model had a 12 ft wing span. I didn't know about Paul Sherlock at the time, but I did purchase the DCRC Symposium's publication a few years later and remember his other models. I will look to see if I still have the article. Thanks for the memory.

??? Why dont you get one? Why not try to learn? Things would be soooo much simpler if you did.
You seem to have an Computer...........
Its actually quicker to do it on paper if you are used to it, but if you need to say change scale you have to do it all over again.
Scaling is really a good feature when trying to fit things in tight areas and it wont work. I hardly draw any on paper anymore.
I do sketches though, Ideas seems to flow beter on paper.

I don't have CAD or even know how to use it.

. I may just get a short kit from Norbert Rauch and just build the center and flying surfaces.
this is simplest, cheapest and shortest way to make big airliner. Look to plane with 1 engine, like DC-10 or TU-154. I spent only 9 month for Tu-154 from Norbert. Perfect plane for 8kg thurst turbine. If you want bigger plane - look to DC10.

Looking for people with airliners interested in participating in the 100th anniversary of Commercial airlines event in Tampa/St Petersburg Florida January of 1914. Anything from the early years, to DC-3s to modern airliners, as long as it is an aircraft with airline markings and modeled after an aircraft used for commercial transport of people/mail. I am willing to work on putting it together if there is enough interest. Here is a facebook page I have set up for the event. Feel free to Email me to discuss the event.
Thanks, Denny

I'll toss my two cents in here. I have been building and flying RC planes for many years. I use Autocad and a lower cost cad program called DeltaCad its free online for 30 days so go download it. Another wing and airfoil design tool is the Holly Grail of RC design software called Compufoil. It comes with hundreds of airfoils most are tested. You can choose one airfoil for the root and another for the tip and then indicate spar locations. Once done with the simple user interface you can loft it. This allows you to print every rib you need to build the wing with spar cut out indicated with a lofted build plan as well. It makes wing design for even the most complex wings easy as pie and you don't need to be a aerospace engineer to use it.

I second your recommendation of CompuFoil. I have had it for several years and wouldn't do with out it. I have even used it a number of times when a friend has a model with unknown C/G. You can schetch in the wing design in a few minutes and get the recommended C/G.

Currently I am building the F-94C and used CompuFoil for the wing design.

Tenacious, your post brought back a 2 year old thread from the grave to offer something that should really have it's own thread. Please repost as a new thread and then I'll remove your post in this one.

Since the thread had an airliner I thought people interested in the thread might also be interested in the event also. You can delete it if you like. guess the thread can go back to sleep

The more I think of it, why is an issue if I invite and inform people that might be interested? Are there rules about who we can speak to and what subjects? Kinda surprising you have an issue really. I dont think the people with the airliners minded. Please let me know what subjects I can discuss in what threads so I will know in the future. And the thread looks active to me, two new posts in the last few days, not counting mine.
I have been communicating on RCU for years and have never heard of anything like this being an issue. Please explain what the new rule is or issue is here.
Thanks, Denny
