i was a bit wary abt going 2.4 in the begining so,i went for frsky as this was the cheapest way to try it out,i put a module in my futaba ff9 and bought the rx stuck it im my wildthing the range was more than i expected ,that was over 12 mths ago never looked back,now im complete frsky, glad i did it ,would recomend FRSKY,
