Hey all, just giving my bird the once over and realised I need a few bits and pieces. Got my new antennas for bird and goggles and went to fit when I realised xt60 battery connector was loose. It is mounted to frame with 2 x small silver Phillips head screws. Only one left as one has obviously fallen off. Any ideas what size? Also need new o rings for motors for the props? Again not sure on size? Also looking at trying 4 blades, recommendations? Vv I know you have been trialling how’s it been? BTW bird is Diatone tyrant s 215. Cheers Wayne
