My favourite build for some time, and one I'm finally posting after moving from a Tracer RX to the new Matek ExpressLRS R24D receiver. This is now perfect and I'll keep it this way for a while.
I started experimenting with larger toothpick frames a long time ago, and I've flown this since the frame was released. The 1505 motors are, in my opinion, a perfect match for a light 4" build. If I had to change anything I would swap the full-size DJI camera for a Nebula Pro, but that's not going to happen due to supply issues.

I tried a bunch of props before settling on either the Gemfan 4024 bi-blades or these gemfan 4019 floppy props. The floppy props allow a really convenient carrying size and I'm a sucker for lemon yellow!

Canopy is actually an analogue model, I didn't see the benefit in 3D printing the long legs as plastic hex standoffs are more rigid and add no real weight.

AUW is sub-250g with a 750mah 4S. Plenty of power for ripping around.
