my 1st micro buy was a hubsan 4x (very nice as there are more settings in the controller for this quad than any other out there currently?) if you want a micro that feels like you are flying one of your "tuned" multiwii builds get this!
then i got 2x syma x1's because they bind to a 9x and were £29 delivered
if you want a quad that flies like a kk board with "decent" firmware on it and you have a 9x and no interest in flipping get this!
if you want to flip use stock tx "for now"
