I just ordered a bunch of parts from heli-fever, and happened to also find all these BH parts in stock there so I ordered them too.
1 x EK1-0213(SK015) E-Sky Bearings (3mm hole) (EK1-0213) = US$2.50
1 x EK1-0228 E-Sky Center Hub Set (EK1-0228) = US$6.75
1 x EK1-0229 E-Sky Rotor Head Set (EK1-0229) = US$6.75
1 x EK1-0231 E-Sky Paddle Control Frame (EK1-0231) = US$4.38
1 x EK1-0234 E-Sky Pitch Control Link (EK1-0234) = US$3.13
