I am building two of these models without a plan. I need a measurement from the leading edge of the wing, back to the hinge line of the elevator. also need the width or cord of the wing. Also is the wing incidence 0 degrees.

Or, perhaps a drawing made from the original Sterling kit. I built two Beginner's Ringmasters from them.  Just as an aside, I modified the construction by using 1/8" square spruce for a leading edge to help with crash protection.  otherwise, I built to the drawing.

The difference being that I posted plans for the Beginner's Ringmaster (as requested) with a slab wing and yours is the Baby Ringmaster with built up wing.
The plan I attached is Pat King's version and he gave me his permission to copy and share around his plan.

Phil,

I neglected the answer on incidence.  As you can see from the traced fuselage from the Sterling kit, there is incidence in the stab.  But it flies just as well with zero incidence.  The Pat Kind drawing doesn't have any incidence.  If you never plan on flying these inverted or trying outside loops, the incidence is fine.  But it's really up to you.

Folks im sorry I wasnt very clear on this. I have the Pat King PDF file on this plane. The problem is, it doesnt have many measurements on it, and I havent been able to get it printed out yet. Im going to make one more try to get it printed today.

It is easy to measure wing root, you need a drawing software. A demo is enough for this. Example: Wingspan is 1000 pixels and wing root is 400 pixels. Wingspan is 30 ins, so what is the size of wing root. A simple ratio calculate.

If you want I can measure it.

IMO it is kinda stupid to print a plan and not have a scale drawn on it. This print I have only gives the wingspan so you can scale from that.
Or maybe Im missing some thing? I used to read construction blueprints and they all had a scale.

Hi,

looks lile someone had done it allready up above. You can use the 'measuring tool' in Adobe to put measurements onto the plan. The thing with that is it can sometimes be out a bit as the pixels per mm and screen resolution, and the tool used to create the drawing can mess things up a bit. Happens with OZ plans as well. Often people creating the plan are not engineers or even if they are engineers they are doing their best to be helpful by spending time creating the plans. Though it does seem odd to go to so much work and not put dimensions on the plans.

I am creating a plan for one of my planes as it is too windy to fly and its a lot more work than I had expected, and in my very very dim dark past I was invlolved in writing the core engine for the Eagle 3D cad system. Fun times IBM Power PC 750 GL RISC assembler. Oh the pain, the pain. (" Dr Zachary Smith") . lol!

Goodaye Robert, its in Adobe Reader. Well this is how I do it using Adobe Reader. From Adobe Reader -> Tools -> Measure The the measuring tool appears in menu above drawing. Select measuring Tool and then you can select Snap Types and Measurment types. To get the best from it, sometimes you need to go into the menu options Edit->preferences->Units->Page Units and set the units the page was drawn in or what you want to measure in. Also via the menu Edit->preferences->Page Display set the resolution for the units. Even when this is correct, when you print the plan it can be out by quite a bit. Thank you Print Drivers! Lol. Also sometimes when you zoom to 100% which should be the correct size and measure it with a ruler in your hand against the screen, the screen display is wrong, and you need to reduce the Zoom setting till it is correct. Can take some mucking around some times to get it right and sometimes its absolutely spot on. I have had plans from OZ that are spot on and others needed lots of twaeking to get right. I think it depends on the tools used to produce the PDF. Some tools do not export to PDF very well, and others require an intermediary tool to get to a PDF. If the plans are produced using the Purchased Adobe tools then they should be accurate.

Hope this helps and doesnt confuse. Adobe Reader is a "Free Download", but then it wedges itself in and consistantly downloads updates for itself and wants them installed. Its a constant battle to disable the auto update of Adobe reader, especially in Windows 11.

lol! I loved that show! I used to run all the way home from school to watch Lost in Space, and an Australian one Aunty Jack https://en.wikipedia.org/wiki/The_Aunty_Jack_Show for which I credit my developing a sense of humour for the bizare and rediculous. You wouldnt be allowed to create a show like Aunty Jack these days, it is just Too Wrong on so many levels, but the wrongness was NOT intended to be literal it was very clear satire. Just like you could never make a movie like "Blazing Saddles" today. A movie that was clear satire.

Ooops. Offf track. Sorry!

A nice start to two great and upcoming planes there. If you need any other measurements from a Sterling Beginner Ringmaster, feel free to ask as I have mine here in the house.

Hi Chevy phil,

That will fly great.
Do not forget outer wing tip weight.
With that tank,
I am guessing a 10+minute run...

Phil,

Those look great! I especially like that you're using the Wen-Mac engine. Wen-Macs are my second-favorite 1/2A engines. With that tank I'm guessing 5-6 minutes.
