Title: 1920 DAYTON-WRIGHT No cal
Post by: John Kourbanis on Feb 07, 2026, 01:00 AM
During my childhood i was playing a lot with rubber band let's say ''no cal'' models,but only no cal they were ;D ..they were too heavy kits that my father bought me during 90s..now it's time to built from a plan, a real no cal model plane ;D .
So i decided to built 1920 DAYTON-WRIGHT from a plan of a flying-aces magazine that G.Kandylakis borrowed last summer.

John,
I'll be watching this build with interest because the Dayton Wright is on my  shortlist for my first attempt at a NoCal. I was going to base mine on a the Jetco peanut plan on Outerzone not realizing there was a NoCal plan at FAC.
One point of note is that the FAC plan calls for carbon stiffening of the motor-stick; this isn't allowed in the UK No-Cal rules. So check what is and isn't allowed at the Nijmegen contest - also if a minimum airframe weight rule applies.

Good points Steve, here are the rules from the IIFI rulebook.

Abdrew, that is most interesting and most rare, a nose heavy rubber model...

Hi John,

I have another No-cal plan by Ross P. Mayo of this racer. If you are interested, I'll post it here.

Cheers
Alex

Hmm, I can't upload it here, because of the 256kB limit.
Uploading to the plan gallery didn't give an error but it's not listed either.

Weird.

For the Plan Gallery, George has to give a final approval before it becomes available and his time is limited.  If it's not up in a day or two, I would send George a PM

Good morning everyone,

first things first,

the plan John is building from came from a printed issue I got when I was subscribed to the F.A.C. Newsletter back in 2011.

As I posted in the resources board, F.A.C. has made available for download quite a large number of previous newsletters, this one included.

https://www.flyingacesclub.com/Newsletters/FACN258.pdf

As to the plan Alexander uploaded to the plan gallery, it comes from the same newsletter, #90, 3/83
https://www.flyingacesclub.com/Newsletters/Issue90-16.pdf

Since it is online free available for download and since the proper credit is given, I am releasing it to the plans gallery, hoping noone objects to that.

The Flying Aces Club Newsletter has a great many plans published over the years, with a very full index for searching, well worth a look.

George

George, thanks for the extra info.

There are some good pics of the preserved airplane here DW-Racer (https://www.thehenryford.org/collections-and-research/digital-collections/artifact/135079#slide=gs-192445)

John,
Your build is going well.
I would be grateful if you could tell us the weights of the uncovered parts, wing, fuselage and tail. And the weights after they are covered.
Keep up the good work,
Steve

Thank you Steve!
Weight after sanding is 1,9 grams.
Now i preshrink my tissue paper..the colour is gray as the real plane.

John, thanks for the weight info. I would be interested in knowing how much weight the covering adds.

I found an earlier incarnation of the following when building my nocal useful:
https://volareproducts.com/new2024/how-to/how-to-don-ss-indoor-nocal-tips/ (https://volareproducts.com/new2024/how-to/how-to-don-ss-indoor-nocal-tips/)
6 grams for an indoor nocal is heavy! For a really competitive model, you'd want something with a low aspect ratio wing, for a light wing loading. The article by Don Sluszarnick (sp?) discusses this. My Wildcat nocal came in at 3 grams, but a real expert in our club built a Japanese fighter with a somewhat narrower wing which came in, if I remember correctly, at 1.8 grams. Of course the guys in the club decided to add a minimum weight rule.

I suspect that, for a 6 gram nocal, a low asoect ratio with something to address the induced drag might be best. Maybe a big gap biplane, such as the Priesel Kep?: Priesel Kep plan (https://outerzone.co.uk/plan_details.asp?ID=3889)  It's almost as ugly as a Blackburn Blackburn though, and I recall a discussion in which Don wrote that nocal biplanes are hard to trim. I've seen a patent drawing for a ground effect craft with a c-wing, but I don't know if it was supposed to be able to fly OUT of ground effect. David Dodge, a flyer from Connecticut, had a V-173 nocal that flew well, even in a room that was only about 50 feet square. I'm guessing it weighed considerably more than 6 grams, though. Those big props, if turning outward, ought to reduce induced drag, as long as they're not counted as part of the span. If you're not familiar with this ridiculous aircraft, check this out: https://en.wikipedia.org/wiki/Vought_V-173 (https://en.wikipedia.org/wiki/Vought_V-173)
It was expensive and complicated, but it performed well on relatively low power. I recall reading that it could fly very slowly and was very good at STOL.
