you can get the thrust 30 from australia, they have an interesting esc/motor combo price including worldwide shipping, takes like a week, maybe a week and a half to get there, or you can get the torque 2818/900 from Atlanta hobby.

there is an apache that also works well, i think its apm 3018-14 if i am not mistaken... it's same size and kv 105 grams 905kv.
