I need the measurements for the larger Ringmaster wing.
I'm not sure of the Ringmaster's spans offered, but I'm looking for a wing around 48" in span.
I would like to know the following,
Span
root cord
tip cord
Thanks in advance.

Hello, I see no one has given you any answers as yet so I can likely give you some. I don't know the cords but the standard ringmaster profile as well as the Super Ringmaster were 42" spans I believe. There was a Ringmaster Imperial that spanned about 52" (Walter Umland offered a kit for this one) and I have a couple of Ringmaster Sportster kits which have a span of 38".
If you are looking for about 48", the closest I know of is the Ringmaster Delux 441 offered by PDK. It's not one of the original Ringmasters but does have similar features and Pat King does put out some nice kits.
Hope this helps a little./

I don't know of any that are 48" but Pat Johnston's Ringmaster 526 is close. It is 49 7/16" span and 9 1/2" tip with 11 3/4" root. This is a flapped model and the root dimension includes the flap. Pat might sell you a set of ribs since he sells a laser cut short kit for the 526.

If I wasn't so lazy, I would send a three view and let you blow it up to the size you want. But, then again if you do a search of Pat King's site you might find one you can use. Of course get permission first.

Charles,
I sent you an email with a S-1 Ringmaster plan file attached. Just get a copy service to print it enlarged enough to give you a 48" wing. The plan has all the ribs and parts shown. Pat King kindly converted these plans from metric and added things like a suspended bell crank and weight box etc. -- so feel free to thank him for his efforts.
If anyone else wants a public domain Ringmaster S-1 plan file (PDF format) that prints out a full sized plan (when printed at 100%) just email me and I will attach the file to my reply.
Hey, I'll try to attach the plans file and an informational Fly-A-Thon flyer file to this post and then everyone can download them. H^^

John,
Thanks for the reply.
I'll check my email for that file.
Yes, I'm talking with Pat King. I believe he will have what I need. Remember, my interest is only the wing.
Thanks,
Charles

Ah Charles,
If it is a Ringmaster wing you are going to use in a different model, you probably do NOT want an S-1 wing. The Ringmaster S-1 wing (pollywog ribs) is not the greatest airfoil and Pat King or Pat Johnston can probably fix you up with a better airfoil. Still if you are planning on using the wing structure the plans file will have the full sized (or larger if you scale it up) wing structure and you can just substitute different airfoil ribs to get better flying model.

John,
Yes, I have absolutely no interest in "tadpole" as I call them airfoils. I also don't like making wings.
Pat has a couple of wings, one being the 45" with 441 sqs. It could work, I could add a few ribs at the tip. Done that before.
Thanks for the reply!
