Cheers Col.
Might just stick with the 18 amps Plush ESC's then.
Some motors (200Watt+) like the NTM Prop drive suggest around 30 amp ESC's and I know the DJI 450 comes with 30 amp ones too.
DJI 330 comes with 18 amp ones though and they are the same motors!
Ive only read good stuff on the SunnySky motors - and they look good value - so may wait till they are in stock at Banggood
