I just spent $900.00 on this typhoon h to find out I have to register it . and I may not be able to fly it on my Owen property . but those nut jobs can fly loop tie loops and all kinds of other crap be cause of the public density per square mile the same as cable. cant fly it at my other property because it lies with in a boundary of A air port . then again I see them fly extremely low over my house on there approach to the air port . where's the justification.
