Decided to rebuild my 6s build (https://rotorbuilds.com/build/5684). Last frame was too tight, so I ordered new lightweight frame iFlight RACER iX5S. Composite material is very strong. Other components I took from my old build - T-Motor F80 1900kv motors and F45 ESCs, FuriousFPV FORTINI F4 flight controller and Matek HUBOSD8-SE. All components can handle up to 6s. Removed XT60 wires, added 680UF capacitor.
