Wayne, what would you charge for a cardboard version of this? I want a ply one also but can see using the CB occasionally for temp storage.Just wanted to share our new project, something I have been wanting for a while. A stand you can use for storage, transport and use at the slope. Will be wall mountable, and be able to be secured in the car or at the slope.
Seems to fit about all of the 60" and smaller gliders we have around here.
This is the cardboard prototypes:

Couple of small changes and should be cutting wood tomorrow.
It is intended for smaller gliders that you don't need to take apart. But would also work very well for larger gliders if you only wanted to use it as a stand. Not great if you have really fat fuselages like scale ships. Ahi fits with the tall fuselage.
Other stands we have played with in the past are all too wimpy. Usually cut from foam, and can't hold up to a breeze at all, even in cardboard mockup this one is more substantial than those. LOL
The vertical mount at the top is going to be best for flying wings. We could add an extra slot, so we did.
I think we will be kitting these.

Which thermal race is it where you get extra points at the end based on how far away you are from landing at a specific point? Was thinking that may be a fun little contest to have at sunset since you have to swing back so far and than come back in to landing zone.

Methinks spot landing.
Southern California Soaring Clubs association would have a duration with spot landing. Duration was to get as close to your time as possible for the round(ie 8 min) the landing part was a 100” radius circle and the center was 100” so you got how ever many landing points based on that. So if you hit the 45” mark you got 45 points. Out side the circle was a zero for the landing and off the run way was a zero for the round.
It’s harder to land in the 100” circle than you think. Also we would have more than one landing spots so as to not tie up traffic with judging.

yeah i dont remember exactly which race it was. General idea being just to have some fun trying to hit a landing area with a plane you dont care too much about. Maybe its like cornhole. whoever is closest to the hole wins. Yes you can knock people out of the way.
Pretty sure we will bring the cardboard prototypes. You will want to keep them dry though.. You are welcome to them. I'd like one about 50% size for the Mini Solus'. They can all have a parking garage together.

Stopped by aloft yesterday and picked up some epp to cut something for @Wayne. I started thinking of something quick i could cut out as i learn how to cut EPP since i havent had it before. I remembered a build thread from back in 2013 on rcgroups for a slope wing called the Starfire. The guy posted everything about it including dimensions, sweep, airfoil, etc. So it was pretty easy to input it into devwing foam. Heres a test cut i did out of insulation foam to make sure the files work and the 4 pieces match up. 48" wingspan and pw51 airfoil as he designed it. Original thread here:

If you notice the blue masking tape on the table I was marking it so I can repeat the process and decrease the amount of foam that I'm using when I go to EPP. IE yes I'll cut a few

Ill build up a a few of the starfires depending on how much time i have before sunset. Should just need to drop in servos, electronics, and put in control horns. What's weird though is the recommended CG in the build thread. I have been making pw51 airfoil planks for many years now and every single one of them i have used peter wicks 22% recommendation and it has been great every time. In this case the recommended CG in the build thread is around 140mm, but cg calc is telling me 185mm. Which is almost a 2 inch difference. Thats huge on a little wing like this. That would be crazy nose heavy if i do what they say.
CG i found is 185mm
Recommended CG: 137
Sweep: Inner cores = 30 and Outer cores = 15 degrees.
Inner core: Chord 280 & Wingtip 230mm, Span = 278mm
Outer core: Chord = 230 & Wingtip 143mm, Span = 330mm
