Again, AMA has already published endorsement of this system at AMA fields. The question was could it be used with somethign other than parkflyers.
Since there is no definition of a parkflyer, unless Spektrum has published one, I don't see how you can violate the use of the radio.
I agree with this statement. The last paragraph is why you will not get a definite yes or no from the AMA.
We already have several 72 MHz park flyer receivers (GMS, Hitec Feather, etc) and this question has not come up that I know of.
