Also, how do you like XT30. I am using BT2.0 because better batteries are available and I think additional weight may cancel out XT30 performance. Do you see a difference?

Happy to share the tune.

I've always used XT30 as I have a ton of GNB 550 1s batteries with XT30. BT2.0 should be fine.

And here's the canopy .stl

https://drive.google.com/file/d/1yeCvCKpTy0-qOU6F4bpOmLEGwgyhXoXY/view?usp=drive_link

Thanks for sharing! It flies much better on your tune. Amazing job

Could you share battery stl also? I am tired of using rubber bands, because battery eject often

No issue with the ESCs. I now have two of these same setups and have flown 50+ flights pushing them hard. As noted in my comments, I've built many of these Babytooths with the same configurations. I have a few that I've flown many hundreds (maybe thousands) of flights with the 1s 5amp ESCs and they are fine. I've personally never blown an esc on this setup.

awesome news im sending it then! as far as the tune goes are you running whats already on the aio or do you have one? i literally have this exact build same frame, motors, props and all. i just have everything soldered up to the betafpv aio but im swapping it to the aio 5 now.

Custom tune. Happy to send it to you.

Thanks so much! And you are so right. It was a pipe dream only a few years ago. I cant wait to see what a fee more years will bring.

Faebu FPV is a great designer, pilot, and friend in Switzerland. I have probably built 20 1s toothpicks on this frame. He also designed the printed battery mount on the bottom of the frame.
