Putting a spin on the rotary wing, as we know it.

Yeah, I know.. The post title is crappy and cliché.
On that note, I'm going to begin delving into my archive of slightly unique things.

First up... SR-1. Simply because I'm garbage at titling. 
I much prefer designations, I suppose.

Designed and built in 2017, IIRC. May have been earlier, but close enough for now.
Not much to it... Balance is the most important thing.

This was recorded at the soccer dome that was being used for the indoor fly at the 2018 Toledo show.
T'was a shame that they only did it once in the few years I attended. 2018 was the best of their final years.

Not sure if Instagram still supports embedding anymore, but I'll give it a shot. If not, I'll upload it somewhere else, and drop it in an iframe or something.

That is awesome (the embed worked fine). You could have called it "painting the ceiling" because it looked like a paint roller going across the ceiling at one point. How much research did you have to go through to build that? 

I think the first "odd" build I am going to try is either a lifting body or a blended wing concept. 

I always hate it when cool events seem to disappear. We once had a really cool autocross event set up at Bristol Motor Speedway. Then I guess one event there were several regulars that didn't make it, folks saw low turnout and never came back. It wasn't sanctioned by those weenies at SCCA either. So it was one of those things that was kind of barely making it, then turnout got low, so we were losing money, then the owner raised the rent, and that was that. Still miss that nice 2 year stretch of the "glory days" of painting blackmarks all over a wide open parking lot. It was really fun when the cops jumped in and took their cruisers around a couple of times too. 

Stupid question, is that fashioned after one of those vertical wind turbine blades? I forget what they are called.

Yeah, everyone refers to it as a paint roller.
I actually don't remember what I was doing when I scratched that together. I do recall that there was a guy that was fiddling with stuff that took advantage of the Magnus effect, a few years beforehand... But I don't recall who it was.

On that note, yep. It's a variant of a savionus rotor.
The awkward designation, SR-1 is a bit of a reflection of that.
I've since revised the design a bit... SR-2 is sitting on the basement floor currently.

The rotor will be a bit more rigid in this revision, with the addition of a central strut between the important spinny bits. I've also changed the geometry a bit to change where the forces will be going on the "airframe."
The aim was to get the balance point out a bit further in level flight as well, to gain a bit more forward speed... but not sacrifice the ability to pull loops.
This one is also a pusher, so that should make things more interesting... at least for the launch.

I'm also planning on finishing a tiny one. I've got some 1x3mm bearings that would be perfect for the application.

I have some RC car bearings I bet would work well. I was thinking of doing one off to each side of the fuselage kind of more traditional, but I like the way your idea broke the mold better.

Best of all... when you're finished cruising it around, just cut the throttle. She flutters down nicely, albeit vertically, with no power.
Also, it's incapable of stalling... At least in the traditional sense.
