I really want a quad that I can fly indoors (possibly on 1S or 2S) and then take it to the back yard and have enough thrust to work on tricks when I don't have time to go to a park and fly the big 5" quad.

I've been looking at brushless micros, and the pepperfiish build looks very interesting, but I really want a frame with some reasonable prop guards.

While looking for a frame with 16x16mm mounts, I learned from the fpvchat slack that the awesome guys at Hoverbot are up to something new. I couldn't wait to try it out!
This build uses the Hoverbot Ultralight Prototype frame, and is just 7.3g with prop guards. The wheelbase is 80mm and is for 2" props.

I wanted a durable cloverleaf antenna, so I'm using the IBCrazy Cloverleaf, which is 1.1g when trimmed down (vs .6g for a whip).

For the 3d printed parts, I got the spacers printed in TPU, and I'm using the 20* camera mount printed in ABS.

I compiled a huge list of 2S batteries at https://docs.google.com/spreadsheets/d/1B-aosnNQKenpLulhH6i1mDSqhqQvy84nccwozwdf1sQ/edit#gid=0
But ultimately I've decided to go with these: https://hobbyking.com/en_us/turnigy-nano-tech-450mah-2s-65c-lipo-e-flite-compatible-blade-130x-eflb3002s35.html

I fly indoors with 2S and a throttle curve to make that sane. Full throttle 2S indoors is a bit too much oomph for my skill to keep it out of the ceilings. OpenTX config for telemetry alarms for 1S/2S as well as a switch that enables 1S / 2S "indoor mode" / 2S mode. Indoor mode has a reduced linear throttle that hovers at 50% instead of 30%.

AUW with my ghetto 1S is 52.6g, AUW with the 2S 300mah is 54.7g. AUW with my go to 450mah 2S battery is 61.1g. Those 450mah 2S give me ~5m30s flight time indoors!

The more I fly this quad, the more I love it. I've not touched the tiny whoop since.
