i have had one of these txs there a slightly upgraded flysky FS GTB2/3
item reasonble value for money it is however unfortunate with its "model number" relating to internet slang
my only issue with it was when using digital trims it went the other direction to what i was expecting !!! if my car was pullling right you would think to trim "Left" ,my car went further right
as previuos posts reset trims to neutral and recaibrate ESC first
