BrainFPV Radix Li 20x20 Flight ControllerThe BrainFPV Radix Li takes everything you love from the full size Radix FC, and puts it into a tiny 20x20 board.. The two main features are a robust Bosh Gyro, and a fancy modern OSD chip. Traditional betaflight OSD's use a functional, but outdated OSD with limited features and update rates. The team at BrainFPV wanted something better so instead uss a graphical OSD chip that enables alot more features, and it just looks nicer. The Bosh Gyro also

The BrainFPV Radix Li takes everything you love from the full size Radix FC, and puts it into a tiny 20x20 board.. The two main features are a robust Bosh Gyro, and a fancy modern OSD chip. Traditional betaflight OSD's use a functional, but outdated OSD with limited features and update rates. The team at BrainFPV wanted something better so instead uss a graphical OSD chip that enables alot more features, and it just looks nicer.

The Bosh Gyro also mean that this FC performs great in the air. Other than that it has all the other features you expect and need from a betaflight FC.

Please make sure to read the quickstart guide before using this flight controller, as the firmware flashing is slightly different:

Compared to the Radix, the Radix Li is:

  • Smaller (20x20)
  • Has a 5V@500mA Regulator (3-6S Lipo input)
  • No Baro
  • No MicroSD slot
  • No Analog RSSI input
  • So ridiculously cute.

Subpar everything
Format: Hardcover
I read almost all the new Batman comics that come out...I haven't been this disappointed in a book in a LOOOOONG time. So boring. Bad art. Bad dialogue. Superficial/basic characters. No emotion. Half-baked Elseworlds universe (if you going to make some changes - make it worth it!). I could go on. When it got to the "big twist" at the end, my eyes rolled so hard I got a headache. I wish I didn't waste my money on this.

Better than the Chronicles
Format: Paperback
I hope DC keeps on publishing these omnibus series up to the silver age and also the softcover option. I much prefer these new softcover editions over the older chronicles series for several reasons. These STGA softcovers are very big almost twice the stories compared to the chronicles and at a very affordable price. Actually a very good price. Also the paper is one hundred times better, I hated the chronicles' paper. Amazon is wonderful too, they now deliver my comics to my house in Costa Rica in less than a couple of weeks, they always arrive before the scheduled time. Excellent service. The only thing to complain is the reproduction. I consider that Marvel makes better efforts than DC to restore their GA stuff. The Cory Sedlemeier books like the Marvel Comics Golden Age omnibus look like they were drawn this morning. DC is usually quite cheaper and prefers not invest in that. So we get the same results as the old early 2000s Archives. I know today it is impossible to get original art pages of action comics 1-10 But I still think that compared to Marvel DC is very lazy and a skintflint when it comes to restoring their old books.

Got it for my college class, it was a required text.
Format: Paperback
Got this book for one my college class, no joke this was a required text. But overall it was an okay read, only reason why I gave it a 4 out 5 is because I prefer to read books for enjoyment and interest, reading a book for class takes that away.
