bounces a bit at time - at this very moment its £1,774.01 - they purchase in china, send it over here and ship it from the UK so tax, import etc doest apply ... but I know they dont ship the latest models - so you get one with the screw on props and not yet upgraded clamp to move the arms up and down - do if you fancy the new quick lock props that usually will throw you back another £60 for the 2x locking system and 4 pairs of props ...
