This is my 6S 2Fiddy 250g build. It has Xnova T1804 motors, the Shark Byte whoop TX, a Runcam nano HD with M12 lens mod and a Happymodel EP1 Express LRS receiver. It comes in at exactly 250g AUW with a GNB 500mah 6S 90C battery.
I wanted to build my 2Fiddy with a decent battery, so I switched to HDZero/Shark Byte to save weight. The motors are 2g lighter and have a bit less torque than the 2004s but handle the props (Gemfan 5126LR) quite good. Still tons of power and great fun.
How did you mount the vtx? Adapter?
