Review on TCMMRC FC F4 Flight Controller OSD 2-5S DSHOT600 for RC Drone FPV Racing - Upgrade your Drone's Performance! by Robert Petrig

I keep buying these for building 5 inch quads. These are great F4 FCs that support many options. They work great with compatible 40A regulators and other regulators. I have a quad with AIO stack and a quad with F4 FC only with BLHeli 20A ESC for my girlfriend's quad, no problem, they were very easy to assemble. Will continue to buy ESC from these FCs.
