I've been wanting to make one too to fly in front of my house.

https://forum.flitetest.com/index.php?resources/shrubsmacker.81/ I just remembered the shrubsmacker! Its a might mini bushwacker and in the flying videos it can do some 3d flying.
Honestly, I haven't found a good "DIY" version of a foamboard 3D plane yet (although the FT Edge comes close).
But for what you're looking at, I can't recommend enough a Twisted Hobbys Crack Yak.

Bought one of these things last year, and have been abusing the heck out of it. Get a bottle of Foam-Tac and the recommended power pack, and you can fly them almost anywhere. We have an area that's probably about 100x200 ft. to the side of our runway at the field, and I have no problem flying it in there. One of the guys in our club has one, and has flown his 32" wingspan Crack Yak in his kitchen, and his hallway, where he's actually been able to turn off and on the lights with a tail tap.
Oh, and if you crash it? FoamTac it back together and keep flying. It'll take a beating and keep going.

I'm in the process of building a simple foam board one, but probably gonna end up getting a Twisted Hobby's model.
I love mine.
It's more smiles per gallon than I've ever had flying. And yes, i've nosed it in, but it's bounced back with a lot of FoamTac. I've popped props off multiple times and strapped a new one on, even broken the wing and had to glue it back on - 30 minutes later, I was back to flying again!(also, for those flying Spektrum, the antenna-less receivers work wonderfully for these; no need to worry about antennas getting scraped off or broken on a dorked landing)

I'm looking at the 24" wingspan to run an 1806 and 450mah 3s. Any thoughts on that?

For a wingspan that small I would start looking at indoor planes but if you're flying outside it would have to be on a no wind day. After a brief search I found this. Unfortunately it uses a smaller motor. The 1806 motor seems to have gone out of favor right now replaced by even smaller drone motors.

You might look at older plans that use a "C20" motor. These motors are now called 2206 motors and are relatively cheap.

I would definitely be using the 24" indoors or on zero wind days. Hoping to find a local rec center that will let me fly in their gymnasium in exchange for volunteer hours or something.
The DTFB model I'm building now has a 20" wingspan.
I'd say an 1806 on 3S might be overkill for the 24" wingspans. I run my 32" wingspan on the recommended 2305 1500kv with a 2S battery on a 9x4.5 or 9x4.7 prop (depending on what the local hobby shop has in the way of props that day). Twisted Hobbys power combo for the 24" is running a 2202 2300kv with a 2S 350mah battery and a 7x3.5 prop; I'd recommend that over the 1806 with a 3S, since these things are meant to be slow flyers, not speed demons.

I think @Headbang designed a foam board mini 3D plane a while ago that you could also consider:

I appreciate your feedback! I have some 2s 650mah that I can try as well

If you are going to try 3D outside, by all means, take sprzout selection. I have TH "CLIK" and it is design real well which I fly in a dome. Flown members' Yak at club field and with enough practice, you can will do a lot of 3d in the wind. The key to a 3d foam plane it must be designed and balanced right(as well as being light) to handle hovering, flying inverted, as well as knife edge.
To save plane crashes doing 3D, suggest you have hours of flying inverted and doing knife edges and be able to fly them in both directions. That is from left to right as well as from right to left. Why?, when you try hovering, and if it is rotating and not vertical, the escape route involves using a knife edge. Put the rudder in wrong direction and it goes to the ground. How about too abrupt horizontal to vertical direction entering the hover? Plane rolls over and down. So stay 3 crashes high.
Welcome to a new world of flying. Think this is bad, try a heli when you get the urge.

LOL Now you're talking almost exactly the route I've gone recently. I was flying my Crack Yak and starting to get brave with that (even after I doinked it into the ground multiple times) and within the last 3 months, I started up flying a Goosky S2 for my first heli. I can do loops, rolls, and inverted hovers, as well as upright tail first ovals and figure 8's, but inverted figure 8's still elude me.
Here's what I did to help me visualize and think about those knife edge and inverted movements; I made a stick plane. that is, I made a basic profile plane, stuck it on the end of a dowel, and started moving it in front of me, thinking, "When the plane is knife edged going left to right, and the top of the plane is facing me, I need to give it left rudder to keep it level. If I want to turn it away from me, I need to apply down elevator." I'd just flip the plane around and call out to myself, "Left rudder, right rudder, up elevator, down elevator," etc., all while moving the plane in front of me. Twist it around, and I'd have to think about the way that I did the movement.
Now, I 3D printed my practice plane (https://www.thingiverse.com/thing:1517256) but you could cut one out of foamboard and do the same thing - it's really more for visualizing and training your brain to fly in these different orientations.
Oh, and if you get a larger Twisted Hobbys 3D monoplane (like a 32" Crack Yak), they are super fun to "kite" into a breeze. I will take mine and fly it into a breeze, and just try to hold it up at an angle into the wind. Tilt it a bit upright, let the wind catch it and blow it backwards a bit, nose down, power up a bit to fly through the headwind, then nose up and "kite" backwards a bit. This is great practice for throttle control, too, because you learn just how much power you need to apply and what angle you need to have it at to keep it in the wind, and keep it steady, even if you're just keeping it upright.

I had a blast with these this summer. The F4f was fine with the FT "A" motor, but I dont like the sound of it as much as a lower kv 2204/5. https://forum.flitetest.com/index.php?threads/flattys.71085/

Had to modify the transport by shifting the battery and making sure there was prop flow across the rudder,elevator and aileron and this is the result. Noticed I did it from both ways.
Hint: To fly an inverted figure 8, you need to go into the "head mode" of when you move the aileron stick say left, the rudder is moved towards the aileron, and when the aileron is moved out, the rudder is moved out.
So inverted, when aileron stick is moved toward rudder stick, the rudder stick moves toward aileron.
When aileron stick is outward, so is rudder outward of radio.
Again, elevator is needed to keep it at same altitude.
Says sticks in or sticks out when starting the turn.
Lol I can do inverted figure 8’s on a 3D plane. It’s the helicopters I haven’t mastered yet! Total different concept, because it’s like flying everything on a ball, but now you’re trying to move in a mirror, while utilizing only half of the throttle stick to keep the helicopter from hitting the ground.
It’s a LOT of sim practice so I don’t end up with a “dumb thumbs” moment (and I still have a moment or two of those where things go a little sideways and I forget which way is left or right, or that I need to tilt the nose of the heli up or down in addition to pitching left or right AND giving a bit of collective!)

Although Late to the party here I just want to also add that the ShrubSmacker is an EXCELLENT mini bird, and more than capable of 3d flying. I built two of them before. The thing is way more nimble that it has any right to be. I LOVED flying mine FPV with a camera on the tail. As far as a mini planes goes it was one of the most durable planes I built too, able to take several "oopsie" landings with only a new prop and/or motor pod needing to be put together to get it in the air again. I hardly ever needed to repair the body of the plane.
