I just got the aerohawk and I want to know the pre-flight procedure to follow. How are things suppose to look like, Is there any trimming, balancing that I have to do and how? I have flown the bird about 5-10 times and I am unable to get a stable flight, I get it up about 6ft high and it starts moving all around...what do I need to do for it to be stable in the air...any help is greatly appreciated.
