...the Nano firmware is plagued by bugs. Still hoping that LP will some day unlock the full potential of this great little FC.
What bugs are you talking about? I just looked in the issue tracker and I don't see any open bugs related to the Nano. I've been reading every message in these forums for the last couple of months and haven't seen anyone mention any bugs in the Nano firmware.
Bugs in Raceflight, not LibrePilot. The only issue I encountered with LP is the inability to disarm with a switch on my old transmitter (two way switch - dx6i), which is no longer happening with my Taranis (3 way switch). That left a few scars on my finger.
Another thing I have to research is ''airmode.'' I enabled it with the help of some members here, but the quad had very strange flight characteristics as if it were in auto level mode. Still have to rule out user error on that one.
Benefits of Betaflight/cleanflight from what I have read. Newer implementations of Acro +, voltage dependent PID adjustments (new), continuous airmode improvements, Frsky telemetry support, one wire ESC programming. Just a few that I would like to try personally
