Seems to be OK so far (a few weeks). Pads are reasonable. Connectors are nice. I would have preferred and sdcard to internal flash, but I can live with it. Worked out of the box with Betaflight. I then used their INAV firmware download to flash INAV, which worked too. Haven't flown too much, but everything seems to work, and the price is right. Read more

I sure wish I could still buy a SpeedyBee F405 flight controller to replace the one I smashed, but the days of inexpensive, widely available FPV components are apparently over for the foreseeable future. So this is a perfectly cromulent 30x30 flight controller. Solder it up, and it works. I like having the barometer, and 128mb for black box logs is generous. Too bad there's no Bluetooth--I've become accustomed to using it for tuning. Be careful when connecting to an ESC! The diagram on Amazon's product page is correct, but the instruction manual that came with the FC is not. Read more

board is listed to be able to be used with Inav... but when flashing the f405 is not listed under the usable boards now the f722 is listed but this firmware cannot be used with the 405.. so if you are getting this for Inav get the f722 not this one. Read more

Great flight controller. The pads were not labeled the same as the instructions say they are. So be sure to check the labels on the controller itself before soldering. Had to bust out the magnifying glass to see them but that’s probably because I am getting old. I only wish there were more flight controllers with led solder pads at all the corners. Read more

If you are Skeptical or on the fence DONT BE. I am amazed by the quality! Its not very often a OPEN SOURCE piece of hardware surpasses commercial hardware in any aspect. This FC and The Flycolor 55a ESC is far under valued in my Honest Opinion. I will forever check radiolink First from NOW on. Read more
