2nd flight on the Furibee Fuuton, OSD and VTX died mid-flight and has not come back. Stock everything. I bypassed the OSD and vTX only for the arm to break 2 flights later.
This frame is a single lower 3mm carbon plate made of cheap knockoff carbon with countersunk bolt holes that further weaken the arms, The main FC board failed after the second flight with the OSD and vTX dying for no reason. Bought from GB who stuffed me around with generic service replies and request for me to do things for items unrelated to the warranty claim. Paypal came through in the end and sorted things out, this frame is now in the bin.
