Bardwell F4 Flight Controller V2.1 AIO FC w/ OSD is backordered and will ship as soon as it is back in stock.

RDQ has teamed up with Joshua Bardwell to bring you this AWESOME Flight Controller. The Bardwell F4 has been redesigned with V2 of the extremely popular Flight Controller. V2's 9v regulator and OSD circuit have been completely redesigned to make them as robust and reliable as possible. The current sensor max has been increased to 240 amps after reports that some users were exceeding the 130 amp maximum on previous boards (YOU BEASTS). The current sensor has also been factory calibrated so that you don’t have to go through a tedious manual calibration process to get your amps and mAh accurate. Finally, the 4-in-1 plug has been upgraded to support both analog current sense and ESC telemetry, for compatibility with all ESCs.
