I will have to side with Wright Flyer on this one, having gone the Micro route only to become frustrated and disappointed not to mention if you don't give up what you'll spend on a Humming Bird/Feda will easily equal a Corona in a months time. Yes it's bigger and you should fly it outdoors unless you have access to a LARGE indoor venue but when you put the Corona up for the first time and get a 3 1/2 minute hover on the first flight you'll forget the Micro and just try to improve with the Corona
